"It's all right now." "Thank you, darling." " Tea?" " Mmm." " You phoned the police?" " Yes." "They came round." "You were asleep." "They think your scream frightened him off." "You did scream?" " Oh, yes." " Well, you can forget it." "They caught him a few miles along the road." " What did he want?" " Just an intruder." " They've been after him." " Will they want a statement?" "I don't know." "Maybe not." "It's an open-and-shut case." "Look, darling, I've got to go." "I'll ring you." " Are you sure you'll be all right?" " Yes, really." "Bye." "Bye, darling." "Drink your tea." "Eight-zero-seven Roper for debriefing tests, Doctor." "Thank you." "This way, Roper." "(Shroeder) I assume you're familiar with this test?" "It measures how much strain goes into your decisions." "Yes." "It's amazing how hard we work, even on simple decisions, like whether to have a cup of coffee." "This is your monitor here." "On big decisions, the stress can render a man useless." "Right." "All set?" "Start the test." "Stop." "Thank you, Roper." "Paul!" "Just the man I was looking for." " Me?" " To ask you to come for a drink." "Oh, no, I, er..." "I'll take a rain check on that." " Something on your mind?" " Oh, it's these games." " The tests?" "That's not like you."

"See you." "Oh, Doctor, how did Roper make out in the decision stress?" "Too early to say for certain, but he seemed..." "Well, he seemed a bit strung out." "Indications of supernumerary stress during his last tour of duty." " Any ideas?" " Not yet." "Could be anything - boredom, misses his wife..." "See you." " Ready?" " Ready." "Hold it." "I can't take you out looking like that!" "What do you mean?" "!" "People might say, "Why's that beautiful girl with that old wreck?"" "Well, don't worry." "I'll tell them I married you for your money." " They didn't ring." " Who?" "The police." "Come on, cradle-snatcher." "I'm hungry." "Well, what do they say?" "Not good." "The stress decision tests are positive." "Signs of anxiety, traces of tension and traces of neurosis." "The observers report similar findings." "Decision-making below par, reflexes bad, impetuosity, nervousness." " I don't believe it." " It's all down here." "He's an out-and-out risk, Alec." "We can't take chances."

" His wife, maybe." " All right." " Tell me about her." " Carol?" "She's young, attractive." "Roper's crazy about her." " I could understand..." " Understand?" "!" "Can't you see...?" "That he's a traitor?" "I know." "But it's a matter of degree." "Degree nothing." "It's what he told them that matters, not why." "Well, you say he's crazy about his wife." "We'll see just how crazy." "(Shroeder) 'OK, Roper, take it from the beginning.'" "(Straker) Just a moment, Doctor." "'All right, Roper, so it's your wife."

"I can give you the data, not the significance." "You didn't know what you were doing when you gave those figures?" "!" "No." "Then we're going to have to put everything into finding out." " Get me Commander Straker." " Yes, Lieutenant." "Keep working on it, Lieutenant." "Is there any deal from SID?" "So far, we've got a series of 3-D direction indicators." "What does that mean?" "It's a navigation course in three dimensions, for some sort of space vehicle to steer." " (Straker) 'A UFO?" "'" " Could be." "Well, as you say, Lieutenant, it's not much, but maybe it's a start." "Let me know the moment you have anything." "Flight path..." "But to where?" "Now, let's see what we've got." "Some sort of a flight path..." "And the fact that they chose Roper to do their dirty work." "Why?" "One, because he had access to SID and understood its operation." "Two, they knew he was vulnerable where his wife was concerned." "He's told us all he knows." "Except who his contact was." "Who was on the other end of that phone?" "I want a yellow alert on all SHADO installations." " (Ford) 'Yes, sir.'" " Let him go, Alec." " What?" " Let Roper go in one hour's time." " (Ford) 'Your key is still down.'" " Oh, thank you." "Neat." "You've let the whole base know we're releasing Roper in an hour." "Yes." "I've been thinking about Roper's contact, Alec." "Whoever he is, he would have to be able to radio Moonbase." "He'd know Roper's movements on earth, have access to his records." "There's only one answer." "You mean someone on this base?" "Yes." "Someone on this base." "Let him go, Alec." "We must draw them out into the open." "OK." "Roger, I've got that." "One moment, Moonbase." "Lieutenant Ellis for you, sir." " Straker." " I've had Joan work on the figures." "'What does she make of them?" "'" " They're planetary positions." " 'For which planets?" "'" "Considering the urgency, we had to make an educated guess." "All right, educate me." "The relative position of the sun, moon and earth fits Roper's figures." "One snag - the last set of information is a time reference, but still doesn't make sense." "It's enough to scare the daylights out of me." "Keep working on it." "Out." "Did you swing this?" "It seems suspect." "If Straker says you can go, don't ask questions." " But he's not the forgiving type." " Don't push your luck." "Just go." "Sir, you wanted to know when Roper left." " Do you mean he's gone already?" " Yes, sir." "My orders were to release him in one hour's time." " Yes, but Colonel Freeman..." " I see."
