The time is fast approaching when a person's entire history - educational, medical, criminal, even financial - may end up as a foot of computer tape in some impenetrable central file. Worse still, a man's future career may depend upon the computer's evaluation. This week the Doomwatch team fall under the baleful eye of a newly established security section.

National Security Section: department XJ7. Admission strictly by N.S.S. Pass. Somewhere in Whitehall, two men are watching on a large screen computer narrated read outs on Doomwatch personnel. Barker, the Minister's PPS isn't interested in the basic details, he wants specific conclusions. Commander Keeping calls out to the computer operator a file name and they watch as the computer recommends various actions to be taken on Doctor Quist, Doctor Ridge. Barker explains to Keeping that this work is necessary. It could mean disbanding the current Doomwatch team because of their investigations in Project Sahara. They then turn their attentions to Toby Wren...


The Doomwatch offices and lab are filled with trays of vegetation and pot plants. An experiment has been set up by Bradley and Toby is pleased. 'All we need is the queen bee and we can go ahead.' Ridge isn't happy that his desk is being covered with triffids and moves a tray over to Pat's desk, which, when she arrives and notices isn't too pleased about. 'There's work being done here, you know, apart from running around after Doctor Robson.' Bradley grumbles, 'Two females in one office, it never did work out.' Ridge isn't complaining. The real live doll, as he puts it enters, and she is a very attractive 30 something. She is in charge of the experiment and seems to have the staff at her beck and call. Even Quist is impressed with her. Stella Robson gets Brad chasing up figures and Ridge to phone up Kew Gardens. She respectfully invites Quist to watch their experiment. After Stella hustles Colin, Quist asks Wren if they should keep her. 'You'll have mass resignations if you don't.' Wren sprays the contents of a sealed container with an aerosol upon some shrubs. Quist is called away to an urgent call from the Minister, as the the results appal the entire team.
Within moments, the shrubs are dead, wilting and brown. It's living up to its name – Sahara. 'It would be interesting to see what would happen to England's green and pleasant land A couple of gallons of Sahara sprayed from a high flying plane.' Wren realises it would spread across the country in a matter of hours. 'This must never be used. We must ban it,' declares Robson seriously. But all they can do is recommend. It's the effect on the soil Robson is concerned with. It could take years to recover. Quist emerges from his office and calls in Stella and Toby. He won't brook delay.

Quist asks Dr Robson if her notes are clear and accessible to Bradley before telling her that she is suspended as of now. Orders from the Minister. Needless to say she is shocked and wonders what has she done. Toby is indignant and declares that he can't go on without Stella. 'You can't,'says Quist looking him in the eye. 'You are also suspended.'

Stella and Wren end up in a pub, where he hits the bottle and begins to get quite flirty with the calmer, sober Stella, asking her straight to bed. 'A straight, scientific proposition.' She declines. 'Who do you keep it for? We've all been wondering.' Offended, but a little understanding, Stella leaves him in the pub and goes home. Wren is momentarily upset but then orders another drink, as Commander Keeping enters the bar and joins him, trying to make small talk. Wren gets his new drink and proposes a toast. 'Here's to false hopes, false dreams, naïve idealism and pure fantasy.' He offers Keeping a drink, as the Commander fishes to find out what the problem is, detecting a sour tone to the man. Wren guesses he is a civil servant, and Wren sorts of admits he is, 'I was never very civil though.' Keeping asks what his boss is like. 'He is a great man, a very great man, and I think he believes, he really believes that he thinks he can do something.'

Stella is clearing her effects from the Doomwatch labs and is not keen on Dr Quist asking her where Toby is, feeling it could be quite important. He accuses her of self pity. That stuns her. She tells her Toby is drinking, and Quist was afraid of that. 'With Toby, when something seems intolerable, when he's faced with gross injustice or despair, he goes on the booze. Doesn't happen often, though.' Stella is alarmed, she shouldn't have left him.

Wren and Keeping are drinking some more. Poor Toby is not quite insensible but is getting that way. Keeping explains he works in records, his kind of work. 'Unlike you scientists...' Wren becomes immediately suspicious until Keeping points out the slide rule in his top pocket. 'Yes, now, you'll be very surprised what I use this for!' Keeping asks where does he work. 'Department of lost causes; too little, too often, too late.' Keeping gets the impression that the bar staff want them to leave, and Toby offers to take Keeping to the Pelican club around the corner. Keeping decides that he has taken the afternoon off...

Stella Robson tells Quist that she has enjoyed working for Doomwatch, she thought that what they were doing was worth while. Quist agrees, especially on their current work. He asks Stella if she would be interested in joining Doomwatch on a long term basis. Surprised, she agrees that if the suspension hasn't happened she would. She goes. Quist comes to a decision and calls in John Ridge, whose desk is still swamped in plants. He passes Stella, putting on her jacket silently and goes into Quist's office. 'Poor cow,' he remarks. 'Security is your speciality. See if you can find out who is behind these suspensions.' It won't be easy. Quist won't take excuses. He wants Toby and Stella working back at the offices by the end of the week.

Stella is lying on a bed being comforted by her lover, Jack, a married man. She is depressed about the whole unjustness of it all, She can't tell Jack anything, in the interests of security, and she can't even tell him what he has been going on. He goes to leave, he can't help her if she won't let him, besides he has to meet the wife and kids. Stella is upset. As he goes into the living room, he sees a big envelope on the table 'Project Sahara...' Stella takes it away from him alarmed. They part on more tender terms.

The next day Ridge tells Quist what he has found out. Department XJ7 has been set up by the Minister quite recently, and it is very sophisticated. The man in charge is a commander Keeping – who was at great pains to assure Ridge that it was not a sinister outfit. Quist is shocked. 'Don't tell me that you've been in direct touch with him!' 'Leave off, it's just that these boys are very clever. For example, after my very discreet enquiries, I got a telephone call from Commander Keeping, last night, at home!'

Wren has come in to the office to clear out his desk, and he is very hungover, as Pat noticed. Commander Keeping enters, he has an appointment with Quist. Wren looks horrified to see him.
'How are you feeling today?' Ridge comes in and tells Pat to show the Commander through, and tells Wren that that was the gent who gave him the push!

Quist welcomes the Commander but does not offer him a seat until asked... Keeping explains that
he is a Detective Chief Superintendent, and Commander is an honorary title. He has been an ordinary copper in his time. They get down to business. Quist asks what is Department XJ7. Wren and Stella were blacklisted because of national security. 'A convenient blanket for witch hunting,' says Quist. 'Your team have access to classified defence information of the highest importance.' 'They also had the necessary security clearance until you stuck your nose in.' The Commander is offended and gets up to leave but Quists wants to know why. 'The possible danger to Project Sahara.' Now even Quist is surprised Keeping knows about this. 'Very little. Known I think as a form of environmental attack. Some sort of soil virus. Cheap to manufacture and delivered, I presume, by rocket. ... It rapidly produces a man made desert. The enemy can't feed himself, surrenders... and the soil recovers in two or three years.' That's the theory that hasn't been proven which is what Doomwatch is investigating and needed a biologist like Robson. Keeping won't explain precisely why Robson was suspended at such a vital time. 'Information revealed... confidential sources.' Quist regards this as the smear technique. Showing him out, Quist introduces Keeping to Wren and Robson. He is not embarrassed. 'I trust we will not be meeting here again.' After he leaves, Ridge could understand if it was him they suspended as he was a former member of MI6, and they don't trust people who leave. 'The whole thing is ludicrous. If I can't have faith in my own people...' Wren asks to talk to Quist alone. He tells Quist that he had a bit of drink last night, and met a bloke. It was Commander Keeping. 'Oh, so he acts the agent provacuteur...' muses Quist. Wren can't remember what they talked about. 'If you mentioned one word about Project Sahara, even the name, there's nothing I can do to help you.'

This time Wren is totally drunk in Stella's flat. He is upset that for all he knew he told Keeping everything he knows about Sahara. 'Oh god I'm so tired...' He goes and lies down on Stella's bed and passes out! Annoyed, Stella tries to wake him and the door bell rings and she invites who she think is Jack inside. It's Commander Keeping, come to ask some questions. He notices Wren is out cold on the bed but doesn't feel they need to disturb him. She wants him to go but he explains this is not a social visit, and she has everything to gain to co-operate. She agrees.

Bradley gives Quist a report on his experiments. The soil in the testing box is now a sandy like substance. Quist is determined to get Stella and Toby back. They need a biologist who knows their methods.

Stella is having to explain her background, Her father was Major Robson, an Englishman killed in Palestine by a Jewish terrorist gang although that was never proved. He was pro-Arab, as was her mother who died five years later. Although she was brought up a Christian, her uncle tried to marry her off to an Egyptian and she ran away back to England. He postulates that she still has ties with Syria, and if she could give them a new weapon to destroy the people who killed her father. 'I have no hate in me,' she declares grandly. Keeping agrees.

Over a cup of coffee, Ridge wonders if there is a way to attack Keeping's information. Keeping will have to go through Barker, says Quist, and he will tell him the source of information. Not with good grace or willingly, but he will.

Before leaving, Keeping asks Stella some more questions, this time about her personal life... He comes round to asking her about whether she has a lover? She is, after all, an attractive woman. She is outraged at this intrusion but he reminds her that they are dealing with national security – which stands or falls on whether she has a lover? He asks about Jack, the man she thought had entered the flat. She refuses to answer and he leaves. Toby is still asleep, thinking for a moment, Stella leaves the envelope marked Project Sahara on the side board. A few moments later Jack does turn up. He waited outside whilst the other man was here. She told him, but assured him he hadn't mentioned Jack... Jack is also annoyed to see Toby in the bedroom. She tells him who he is – and that he has no right to be jealous... Whilst she makes some coffee, Jack sees his chance and takes the envelope and makes his excuse to leave. She returns and sees the envelope has gone.

Barker, an unctuous and oily man refuses to divulge the source of Commander Keeping's information. He assures him of the veracity of the information but Quist is not satisfied and is deeply suspicious of his motives. 'My department is concerned with the long term effects of Project Sahara. It is possible that our recommendations could prove uncongenial in some quarters. Urgent research is necessary and you remove the two people in Doomwatch best qualified to deal with it...' Someone is trying to undermine the whole investigation. Barker dismisses this as sheer fantasy and refuses once again to tell him the source of the information. 'If you do not, I will close down the Doomwatch operation as of now. I propose to inform the Prime Minister immediately of the reasons for my resignation.' Barker agrees, he has no choice really.

Quist is shown the computer room, where the inhuman voice is detailing the personality problems of a man called Kingsley. It talks of his prolonged over-draught, his medical condition, a sexual offence, and that he is a security risk to blackmail.... and so on until Quist demands that shut that machine up. Barker asks the staff to leave. 'So Wren and Miss Robson have been tried and found guilty by a computer.' The information collected on people and stored on computers has now been centralised. It was bound to happen. This is a pilot scheme. 'Shortly the entire population will enjoy its benefits. The contents of every application form filled out in a life time neatly stored in that machine. Capable of being recalled in an instant' Barker agrees, a start had to be made somewhere and government seemed to be the logical place. Fresh information is fed in daily, the computer scans this and makes recommendations on its conclusions. It decides those who are criminally inclined. Criminal types in advance? Barker agrees, for sometime now it has been felt that criminal tendencies could be detected if enough information was available early. People can be removed from positions of temptation. 'Are you seriously suggesting that Wren and Dr. Robson are potential criminals?' From information from the police and security services, the computer decided that they are bad security risks. Quist is not impressed. Their lives are ruined because the computer can't be wrong. Barker has faith in it. He demands to see the information on them, threatening again to resign.

Commander Keeping makes a surprise visit on Dr Robson, telling her it will not take long. He asks her if she has anything to add from last night, warning her of the serious consequences of withholding information. She repeats that she has held back nothing, and satisfied, the Commander leaves leaving Stella worried.

Keeping goes to see Quist who has read the transcript from the computer on Wren and Robson. 'Wren has occasional drinking bouts during which his reliability cannot be guaranteed.' 'Stella Robson is considered unreliable because of her Arab background and her assumed antipathy to Israel.' Quist is well aware of this. 'Makes a change from finding communists under the bed.' Keeping gives his conclusions: Wren should have a holiday and Dr Robson returned to her university where she can be a danger to anyone. Quist rejects the recommendations, but Keeping counters that soon he will have a meeting at the ministry.

Meanwhile, in a darkened bric-a-brac shop, a little old man lets inside Jack Foster. It is quite clear that he is being blackmailed about his affair into getting the project sahara information to him. He wants out, this time. The old man has his assistant with him, a tall, silent and very strong man. Foster passes over the envelope and the old man is surprised that he hasn't opened it. He is not allowed to leave. The envelope is opened – blank pages and a note addressed to Mr foster. He is forced to read it out. It is from Stella... 'Jack, I hope you never read this. If you do so it will be impossible for us to meet again.' The old man looks hard and cold at Foster.

Barker and Quist argue it out once again in the office but Keeping thinks this is beside the point.
Quist counters that it explains why he refuses to have two of his people persecuted by a machine.
'In memory and calculation the computer is my superior, but in judgement it is not.' But Keeping produces a letter from the Prime Minister. It reinforces the department's decision. Quist is beaten. Barker beams. 'I'm sure these unfortunate incidents will not prejudice our good relations.' 'What good relations?' There is a phone call from Keeping who stops Quist from leaving. Something has happened. Dr Robson will be needed as well.

At a mortuary, she identifies from behind a screen the dead body of Jack Foster, his face scarred and cut. At first she can't be sure. She examines his effects. Quist dislikes Keepings methods but in this case he had no option. He was deliberately dragged along the road. Murdered. Robson identified the signet ring. Keeping tells her that Foster was spying on her. He was being blackmailed by agents of a foreign power. 'But he knew nothing!' she exclaims, 'the name – that's all...' She will have to prove that. Because she didn't tell him about Jack Foster last night.

After this, even Quist has to agree that it is quite impossible for Dr. Robson to return to Doomwatch. Quist is quite chirpy. He asks Commander Keeping to read the information from the computer on Dr Robson. There was nothing in it about Jack Foster. This perplexes Barker and Keeping. 'Nevertheless the computer was entirely right of its assessment of Dr. Robson,' says Barker. 'For the wrong reasons.' Quist thinks that Keeping took his own individual line of investigation here. He uncovered the existence of Jack Foster. Quist questions him sharply. 'I felt she was lying... Her manner. I've seen women like her before. My trade, Doctor. Thirty years experience.' And Wren? Keeping doesn't answer. Even Barker sees where this is going. Quist conciliates. He won't stand in the way of Wren's withdrawal from Doomwatch on the condition that the final decision is not made by the computer but by Commander Keeping. His threat still stands. 'I have the utmost faith in the commander's decision.'

The next day Quist goes into his offices, ignoring Pat and Ridge and asks Bradley if the test is set up, and to let him know when Toby arrives.

A little later, Toby Wren turns up and is cheerful – he is back. He goes to see Quist in the lab and tells him that Keeping phoned him and told him that his security clearance had been renewed. He couldn't get a word out of Wren sober or drunk and even congratulated him. He has been advised to give up the booze, something Quist agrees with.

Ridge follows Quist into the office and ask what did he use on Keeping. Blackmail? 'Nothing so crude. In this instance, human nature reasserted itself over the machine. When it came to the crunch, Keeping used his own personal judgement.' Ridge knows computers are going to be used in this way, but, says Quist, as long as human judgement has the last word. And if it doesn't? 'God help us all.'

Synopsis by Michael Seely

UK Gold cuts:

Opening close up of the TV set showing the racing and a bar steward turning down the volume in the first bar scene.
Stella going into the bedroom after Wren, as he lays down. He tells Stella that he is sorry for having a go at her last night and falls asleep.
Quist screws up Keeping's recommendation paper and the scene cuts into the bric-a-brac shop. 



Project Sahara was originally called The Lord of the Humans, written by N. J. Crisp, but was given such an extensive rewrite by Gerry Davis, that he was able to claim a fee for his work which was the princely sum of £400, paid on the 4th of February 1970. Apparently, and this has yet to be verified, the original story was derived from a Pedler/Davis storyline called 'Check and Mate' which was originally given over to Hugh Forbes. But, rather like The Iron Doctor, was passed over to another writer to pursue.

The most notable cut is at the very beginning of the episode. As transmitted, we see the sign to the 'National Security Section – Dept XJ7' and then cut to the computer technician (played by Margaret Pilleau) as she pulls up the information on Doctor Quist as watched by a seated Commander Keeping and Barker. You can just see the curtains have pulled apart from the screen in the manner of a cinema!

What we should have seen was after the close up of the sign, the camera pulls back to show a London policeman in uniform, who stiffens to attention as down the corridor approaches Keeping and Barker. They enter the room as the policeman opens the door for them. Keeping, played by Nigel Stock, reminds Barker that they are not fully operational. Barker agrees but this is an emergency. Thinking that this is a conducted tour, Keeping begins to explain that they are in the Terminal Room but that the computer itself is housed elsewhere. Impatiently, Barker wants to begin and suggests that they start with Doctor Quist. Keeping instructs the arrived technician to begin with him.

Then the episode continues as transmitted with the Technician inputting the details into a clattering keyboard... Incidentally, the computer is written to say that Quist's age is fifty, not five zero...

This episode isn't about the titular defoliant that Doomwatch are investigating: it is about the security measures in place to monitor the team. The computer recommends that Quist is monitored at all times! We can assume his phone is tapped. Ridge's certainly is otherwise how did Commander Keeping know about his discreet enquiries? In the third series it is established that Special Branch maintain surveillance on Quist almost all the time.

Vetting in government is a horrible fact of life. There are two types: positive and negative. Negative vetting is the usual checks with the police, making sure application forms are accurate and so forth. Positive vetting is interviewing of friends, former colleagues. It is very intrusive. In the 1960s, the concern, especially after the spy scandals and the Profumo affair lead to a paranoia and distrust especially amongst a left leaning Labour government. The old boy network and school tie and knowing your father no longer applies. The civil service, the judiciary, establishment and the security services were, by definition, right leaning. So, on of the purposes behind vetting was to flush out their political sympathies. To be left leaning was not, in itself a crime – unavoidable in the Labour Party, but affiliations with the Communist Party of Great Britain was, especially if you worked in very sensitive areas of research! 'Makes a change from finding communists under the beds,' says Quist. The vetting was not always successful. It was not until late in the 1990s, that Melita Norwood, by now a 87 year old grandmother living in Bexley Heath who was a civil servant and passed on secrets to the Russians when she worked at the British Non-Ferrous Metals Research Association, which worked on the first British nuclear bomb. Perhaps she met Quist – if he was real! But sometimes the vetting could go too far. Tony Benn was once given a report on someone who was turned down for appointment because his father read The Morning Star... The compiler did note that reading The Morning Star in itself was not a crime but indicative of a general thinking...

But this episode does involve espionage. We have no idea who the sweet old guy played by Eric Chitty represented, or to whom he sold this information. The episode is not against the need for security, that would be ludicrous! Commander Keeping is concerned that Dr Stella Robson (Mrs Brian Blessed no less!) is going to pass on secrets to the Palestinians or the Syrians in order to starve Israel into submission in revenge for her father's death. If so, a few bugs in the Doomwatch offices would have overheard her declare twice that the substance must never be used.

Quist is suspecting that Robson and Wren's suspension is simply to prevent the investigation they are carrying out. Quist refers to clever lobbying in the episode. Is Project Sahara the defoliant that a horrified member of the RAF (who would, presumably, be spraying it from their planes if it isn't delivered by rocket as Keeping thinks), which is one of the reasons why Air Commodore Parks despises Quist in the final episode of the season, Survival Code? Presumably the Ministry of National Security wants the long term effects of Project Sahara to be investigated as the substance is not removed from their labs and Quist is encouraged to find a replacement biologist. Project Sahara seems to be a take on Agent Orange, used by the Americans during the Vietnam war, then still raging. As well as starving the enemy of food, it was designed to remove their cover. This is chemical warfare to put it bluntly. As Ridge says in Train and Detrain, chemical warfare is forbidden under the Geneva Convention, especially to kill plants in a time of war. Project Sahara kills plant life almost instantaneously and reduces the soil to a sand like powder after a day. The Doomwatch investigation is into the long term effects on the soil. The theory is that it would take two or three years for it to recover.

At the end of the episode, Quist agrees that Dr. Robson – who he thought was perfect Doomwatch material, could not return to the department after the Jack Foster business. Quist warns Toby that all he had to mention was the name Project Sahara to Keeping when he was drunk, and he could do nothing. Stella, although did not talk openly about the project, she kept a file in her flat which Jack Foster has seen. That, and her refusal to disclose his existence sealed her fate – and annoyed a number of female viewers who thought that two female scientists in a row to screw up was pushing it a bit. Presumably only men are allowed to make mistakes! Let's not go there, as they say.

So the need for security is demonstrated. But how is it to be maintained?

The computer was is sifting through details and highlighting potential issues, But Doomwatch is warning, as man has the last judgement, then this necessary and inevitable evil is fine. But in this episode it is the computer that makes the recommendations! It doesn't flag up problems for a civil servant or a policeman or a security officer to investigate – it does it for them based on information fed in. The most alarming moment is the scene where Quist watches it in action: their 'victim' is analysed for his bank account details, a minor sexual offence and his medical history! He is regarded as a potential blackmail risk.

Barker talks about the idea that if enough information is known, potential future offenders can be dealt with in advance, taking away temptation. This is a frightening idea that suggests patterns of behaviour, background and environment can predict your future criminality! Just think of it: if your father was a thief, the idea is that you too may become one. The opposite can sometimes be true! Not all abuse victims become abusers. This idea is explored more fully in By The Pricking Of My Thumbs in the next series.

If this episode was done now, data loss (memory sticks left on trains,) and the sheer ineptitude of some of government's I.T. projects would be the issue. Mistakes and so. It features in political comedies such as The Thick Of It.

We are private people. If you have nothing to hide, you have nothing to fear. We've ALL got something to hide, from sexual preference to opinions and health concerns. If we really accepted that argument, then we would have no issues with body searches on the streets or house searches without a warrant. These are safe guards against abuse. What the more tedious politicians call common sense... The majority didn't want identity cards because we have enough identification and numbers to be get going with, thank you very much! The issue is heightened in Britain because privacy is a national characteristic. Yes. Minister, a sitcom about administration dealt with ID cards in an early episode entitled Big Brother, and the attempts to implement safe guards.

The episode is the first not to have any location filming for it and is none the poorer. Judging by comments from other magazines that the third season lacked much film which somehow added to the tiredness and cheapness of the season is ludicrous. Indeed, time Screen thought this episode slowed things down a bit. Nonsense: it rollicks along with marvellous dialogue and characterisation. The acting, as always in a Doomwatch, is top notch.

Barker, first mentioned in The Plastic Eaters as the Minister's PPS (presumably a civil servant who runs a Minister's private office. Or he is a Parliamentary Private Secretary which makes him an MP), is played by Robert James who will later be a GLC man in Flood, he is everything you want in a love struck civil servant/politician, oily and with perfect diction. He is an excellent foil for Quist who is still as sparky as he ever was in the first episodes of Doomwatch. Ridge gets to flirt and Robert Powell shows us his drunk acting along with the ever reliable Nigel Stock.

Reviewed by Michael Seely

Two members of the Doomwatch team, Stella Robson (guest star Hildegard Neil) and Toby Wren have been suspended as a result of a computer assessing them as potential security risk.

For Stella Robson, things are bit more complicated with her being involved with a married man who turns out to have been forced to spy on her. This underlines important information that comes out of Doomwatch, important enough for enemy agents to get their hands.

Nigel Stock is quite effective as Keeping who investigates Stella and Toby. It is particularly interesting when Keeping brought up Stella's backstory.

The final dialogue in the episode between Quist and Ridge is worth mentioning. The dialogue was about the norm of depending on a computer for intelligence in which Quist says that human intelligence will have the last word, if it doesn't - God help us all. Definitely something to think about.
