(DOOR SLAMS SHUT)
Where do you think you are going?
To search. We've got to find those killers.
- The robots can handle it. - So can I!
- (UVANOV): Where do you think you're going? - He's right, Commander.
- (UVANOV): You stay where you are! - It would be quicker if we all went.
We are not armed! There are two killers loose on board the ship, maybe more!
The robots can handle the situation more efficiently than we can.
I just thought you were in a hurry to get back to work.
I am not in any hurry to get myself killed, Toos!
- Thank you very much. - (ROBOT): What were you doing in the hopper?
Don't ask me such silly questions. How did you know I was in there?
(ROBOT): When I got here the gauge showed a high percentage of impurity in the ore.
(ROBOT): I therefore checked.
Well, I'm not surprised. There's a dead man in there. Murdered. Strangled.
- (ROBOT): That is Kerril. - Oh.
(ROBOT): Nearest Voc. Sub-priority Red 4, Section 5-2, V.17.
(ROBOT): Commander Uvanov has ordered that you be restrained for questioning.
(ROBOT): Please do not try to escape again.
Is the Robot Command Circuit routed only through you?
- (ROBOT): I am the co-ordinator. Restrain him. - Easy, now. Don't get excited!
Doctor!
Doctor, you were right.
There was a body.
Two of the robots, they took it to a special place.
(D.84): Please do not cry out. It is important that I am not found here.
Obviously!
(D.84): If I had killed him, would I not have killed you, too?
You still haven't explained what you're doing here.
(D.84): You have not explained what you were doing here.
I was looking for the Do...
I don't have to explain anything to you. You're just a mechanical man, not real.
(D.84): Do you know what this is?
No.
(D.84): I must ask...
I must ask that you tell no one about me.
Is there anyone left alive to tell?
Oh, so we've caught one.
But not soon enough, though.
(LEELA): I didn't kill him. Ask this thing!
You have to do better than that.
- Who are you? - Leela. Who are you?
- Why did you kill him? - Try that again and I'll cripple you.
- Why did you kill him? - I didn't. Tell him.
That is a single-function labour robot. D-class. D for ''Dumb''. It can't speak.
Has anyone told him that?
You have cost me and the company money and you've killed three people.
Can you think of any good reason why you shouldn't be executed on the spot?
No. But you can, otherwise you would have done it.
Don't get clever with me!
We've caught the man, too. Seems he killed Kerril.
Poor Cass... You must be stronger than you look.
You must be stupider than you look if you think I did that.
- Where is he? - (POUL): They're taking him to the crew room.
- Come on, then. - Why do you use these?
Robot deactivation disks. There was one on Kerril, too.
- (UVANOV): Why did you have to tell her that? - (POUL): I assumed she knew.
If we could have got her to tell us what those corpse markers were,
we'd be halfway to a confession.
Halfway to two confessions. Dask knew what they were.
Which rather rules him out.
- He wouldn't have admitted it if he did it. - Haven't you heard of a double bluff?
You seem very keen to spread suspicion, Poul.
Could it be that you've got something to hide?
We've all got something to hide. Don't you think so, Commander?
Bring that!
I didn't kill him!
No.
Pity, but no.
- Would you like a jelly baby? - Shut up!
A simple ''no, thank you'' would have been sufficient.
Return to your normal duty.
- Are you alright? - I'm fine.
Cass is dead.
That one's ready to kill. I had to restrain him.
Shh! They're dangerous because they're frightened.
- She murdered him, didn't she? - How do you know he was murdered?
- It's obvious. - You marked Cass for death.
- (BORG): What? - You put a corpse marker on him.
Yes, but I didn't mean anything by it.
- Was Cass the same as the others? - Yes, exactly the same.
- And who are you? - The Doctor. I assume you're in command.
Yes. What are you doing here?
Just standing here, talking to you.
- I should be very careful if I were you. - (WHO): No doubt you would.
What are you doing on this mine?
We're travellers. We came here by accident.
Oh, I see. A hundred million square miles of uncharted desert,
and you just stumbled across us?
- Well, it's a small world. - (UVANOV): Yes...
I suppose it's also a coincidence that as soon as you two arrive,
three of our people are killed?
- Well? - Sorry, I thought it was a rhetorical question.
Yes, it's a coincidence.
Why waste time? We know they're guilty.
- No, we don't. - We just hope they're guilty.
He got trapped in the hopper when he was hiding the body. That's a fact!
No! That's an inference.
I wasn't hiding that body, I was finding it.
It was put there for that reason; someone wanted to kill me, too.
- The murderer? - (POUL): No, the others were strangled.
- Why should he be different? - To put suspicion onto me.
Why bother? You're a stowaway, what could be more suspicious than that?
A dead stowaway.
It's possible that he's telling the truth.
As a lie, it's pretty feeble.
Ever hear of the double bluff?
- Yes, now that you... - (UVANOV): Lock them up in the storage bank.
- (UVANOV): Put a guard on them. - I agree with him.
It gets you out of an awkward situation, doesn't it?
- Why don't you shut your mouth! - Shut yours.
She's accusing me of murdering my friends.
- You never had any friends. - Have you quite finished?
Either one of us murdered them or they did. Which is the more likely?
Erm... There is one other possibility which you have overlooked.
We've heard enough out of you.
You're a classic example of the inverse ratio
between the size of the mouth and the size of the brain.
- Stinking murderer. - (POUL): Stop her!
Come on, Borg! It doesn't matter.
(UVANOV): V.8, lock up these two strangers.
- I still don't like it. - I don't care if you like it, just do it.
Alright, Commander.
There are fewer of us now. We'll get larger shares if that's any consolation.
No, Commander, that isn't any consolation.
Tell me, Zilda: Why do you hate me?
- You flatter yourself. - Let me tell you something.
By the time this trip is over, I'll have more money
than you or your fancy family ever dreamed of.
May I go now, Commander?
Zilda.
(ROBOT): I will kill Zilda.
Thank you.
- Nice of them to leave our arms free. - Yes, I just want to scratch.
- These metal straps won't budge! - Of course not.
The robots bent them as if they were leather.
Yes, then locked the molecular structure.
The result are bands solid as cast iron.
- It's hopeless. - I wouldn't say that.
- (LEELA): What are you doing? - Concentrating.
Every lock can be unlocked. It's just a matter of thinking out the combination.
- How long will that take? - No more than two or three weeks.
- Three weeks? - There are several million combinations.
- You don't seem to take this seriously. - I'm taking it very, very seriously.
I have an uncomfortable feeling that if the murderer doesn't kill us,
the Commander will.
That is assuming they're not one and the same person.
V.21. Eject those figures.
(TOOS): We're nearly 50% under target.
- The first third of the operation. - (TOOS): You should tell the Commander.
Tell the Commander what?
Unless we find a rich vein we'll take the miner back half-empty,
barely covering the operating costs.
Don't worry, Toos. I've never gone back to base with an empty tank yet.
- This trip could be different. - It's certainly been different so far.
- I'm taking my rest period. - Oh, are you?
If you don't mind, Commander.
I'll have to change the duty schedule. She needs a rest after one hour on deck!
Rest time is an entitlement.
Yes, but this mine is already undermanned.
I don't know how we'll make our quota.
(ROBOT): Lucanol stream, bearing 2-4.
- Yes, I see it, 16. - Stream bearing left.
It's alright. Relax, Toos, relax.
- (ROBOT): Ground centre veering 7-2-0. - We're losing it!
Right centre, four degrees, V.16.
For your information, Toos, I've never lost an ore stream yet.
Right centre, two degrees.
Someone's coming!
(DOOR OPENS)
- I'd like to help you. - You could undo these clamps.
You said there was a possibility that we had overlooked. What is it?
Be careful of him, Doctor. He's not what he seems.
- Why do you say that? - You move like a hunter.
- Watch all the time. - Are you a hunter, Poul?
Never mind about me. What matters to you is Commander Uvanov.
I know him and I know that it's only a matter of time
before he decides that it's a waste of food, water and labour
keeping you alive.
- That concerns you? - I don't think you did it.
I know she couldn't have strangled Cass.
Not without knocking him out first, and there was no sign of that.
Tell me what you know and I'll try to help you.
Well... (COUGHS)
Thank you.
One of your robots could have done it.
- That's your great theory, is it? - Mm.
Well, my friend, robots cannot kill.
- Their prime directive... - I know, I know!
It's the first program led into a robot's brain
from the simplest Dumb to the most complex Super Voc.
But suppose someone's found a way of bypassing it.
It's impossible! It's just impossible!
- Bumble-bees. - (POUL): What?
Terran insects. It's aerodynamically impossible for them to fly,
but they do it.
I'm rather fond of bumble-bees. Come on!
There's something I want to look at.
Erm!
Thank you.
The first murder happened here.
Tell us about it. What was his name?
Chub, a government meteorologist. I don't know much about him.
He wasn't part of the team, just along to study the storms.
- Who found him? - I did. I heard him scream.
That was odd because he was strangled.
So whoever killed him was strong.
- Too strong for him to resist. - He could have been taken by surprise.
- He had time to scream. - What was he doing here?
We were approaching a storm. He came to get instruments
to send up in one of his weather balloons.
- Where was he found? - He was lying there.
Is that one of his packages?
I think so. Yes, it is.
Good. Imagine you're Chub. There's a storm coming up.
- Pass me one of those packages. - Yes.
It's stuck. It must be jammed at the back.
Come on, in those circumstances you're in a hurry. What would you do?
Well, I'd call... I'd call for a robot.
No.
- (ZILDA): You did it, Uvanov! - Zilda, is that you?
You thought you'd get away with it, didn't you?
- What are you doing in my quarters? - (ZILDA): You filthy liar!
- Toos, take over! - You disgusting man! Animal!
Uvanov's on his way down. What's wrong, Zilda?
Zilda?
The killings have affected her mind.
No, she's found something out.
Wait here, I'll get the others.
If you're right, you can't imagine what it'll mean.
What do you mean I can't imagine what it'll mean?
This isn't the only robot-dependent civilisation in the galaxy.
(SIGNAL) Poul here.
(TOOS): Go to Uvanov's quarters as fast as you can.
Zilda came on the command speaker and accused him of being the killer.
He's left control like a scale 20 blow.
I'm on my way! No, you wait here.
Sit down, sit down.
- What did you call those robots? - Creepy mechanical men.
Yes. You know, people never lose that feeling of unease with robots.
The more of them there are, the greater the unease and dependence.
It's a vicious circle. People can neither live with them nor exist without them.
So what happens if the strangler is a robot?
I should think it's the end of this civilisation.
Uvanov!
Just like the others.
Yes. Just like the others.
S.V.7 to the Commander's quarters.
She really hated me, you know.
I did think that when this trip was over and I was really rich...
I must be getting soft. There's more than those two on board.
Get the tin brains to make another search and do it thoroughly this time!
- No, Uvanov! - Get out of my way, Poul.
I'm confining you to quarters and relieving you of command!
- She was dead when I got here! - And now you were making doubly sure?
Don't be a fool. Get out of my way.
Doctor?
- Something's wrong. - (WHO): That's true.
No, there's something different, something that could destroy us all.
(WHO): You're letting your imagination run away with you.
- Can't you feel it? - (WHO): No, I can't.
(WHO): ''By the pricking of my thumbs something wicked this way comes.''
No, I can't. And neither can you.
Please don't say, ''I told you so.''
- What happened? - Come on.
Toos! What's going on?
(TOOS): Something's jammed the motives.
- What does Borg say? - Trim auxiliary vents.
Nothing, he isn't there. Dask has gone down.
I'm going down there, too. Just try and hold her steady.
(TOOS): Oh, thanks! I'd never have thought of that.
- Restrain the Commander. - (ROBOT): Is he hurt?
He'll be alright, just keep him here!
(ROBOT): All motive units are now on overload. All readings are 10% above safety.
- Halt 60, starboard 300. - (WHO): What happened?
- (TOOS): How did you get out? - Never mind, what's happening?
We're trying to keep her upright.
- You have to cut the power. - If we do that we'll sink.
- Then you'll blow yourselves to pieces. - And us!
- Hello, Toos? - Dask, what's happening down there?
(DASK): I've found Borg. He's dead, strangled.
But what's happening to the motive units?
The drive links appear to have been sabotaged.
- I need a delta repair pick. - No, I need you here at control deck.
- We had nothing to do with it. - It's strange how you're always around...
It's a gift! May I remind you that we'll all blow together when she blows,
if you don't cut the power!
V.14, stop all motive units.
(V.14): Motive units will not stop. Control failure indicated.
- Sabotage! - What's the limit before the unit explodes?
I don't know! 90 percent?
- Severance kit! - Doctor, what are you doing?
Fighting sabotage with sabotage!
Get out of there!
- Come on! - What?
- (ROBOT): All readings are 85% above safety. - She's going!
