Major Cartwright: You know this Royston chap. Brilliant, of course, I'm sure. But the trouble with these scientific types is they can't see the easy way out of anything. It's got to be complicated if it's going to work.
Peter Elliott: What happened, sir? I don't understand.
Dr. Adam Royston: Peter, I'm afraid I don't either. Yesterday the material in that container was giving a danger-point radiation reading. Now, as you just saw, it's nothing.
Peter Elliott: But that's impossible! Isn't it?
Dr. Adam Royston: Yesterday I would have said yes, but this fact is inescapable: The energy trapped in that trinium has been sucked right out of it. And furthermore, that window was barred and these doors were locked all night. So whoever it was came in here must be most ... unusual.
Dr. Adam Royston: Now, Mac, how would you go about killing that?
Inspector McGill: What is it?
Dr. Adam Royston: It's a particle of mud. But by virtue of its atomic structure it emits radiation. That's all it is. Just mud. How do you kill mud?
