"Are you insinuating—"
"Hell, no! I'm telling you!" Ritchie put his hand down suddenly, and his voice calmed. "Ever wonder about those other two big buildings on the premises here, Collins? Well, I can tell you about one of them, because that's where I work. You might call it an experimental laboratory if you like. Sometime later on I'll describe it to you. But right now it's the other building that's important; the building with the big chimney. That's a kind of an incinerator, Collins—a place where the mistakes go up in smoke, at night, when there's nobody to see. A place where you and I will go up in smoke, if you're fool enough to tell Manschoff about this."
"You're lying."
"I wish to God I was, for both our sakes! But I can prove what I'm saying. You can prove it, for yourself."
"How?"
"Pretend this meeting never occurred. Pretend that you just spent the afternoon here, waiting for a girl who never showed up. Then do exactly what you would do under those circumstances. Go in to see Dr. Manschoff and ask him where Sue is, tell him you were worried because she'd promised to meet you and then didn't appear.
"I can tell you right now what he'll tell you. He'll say that Sue has been transferred to another treatment center, that she knew about it for several weeks but didn't want to upset you with the news of her departure. So she decided to just slip away. And Manschoff will tell you not to be unhappy. It just so happens that he knows of another nurse who has had her eye on you—a very pretty little brunette named Myrna. In fact, if you go down to the river tomorrow, you'll find her waiting for you there."
"What if I refuse?"
Ritchie shrugged. "Why should you refuse? It's all fun and games, isn't it? Up to now you haven't asked any questions about what was going on, and it would look very strange if you started at this late date. I strongly advise you to cooperate. If not, everything is likely to—quite literally—go up in smoke."
Harry Collins frowned. "All right, suppose I do what you say, and Manschoff gives me the answers you predict. This still doesn't prove that he'd be lying or that you're telling me the truth."
