"No soap on that, I'd say," Dawson said slowly. "I mean, I don't think they'd have lighted out without finishing us off first."

"No, I think you're wrong there, Dawson, old chap," Captain Small said with an apologetic side glance at his superior. "I don't think they bothered about you two because they knew the jig was up. I mean, you see, they knew that Farmer had phoned us, and that we were on the way. I fancy that their first thought was to get away from here as soon as possible."

"But why take the dead man?" Dave argued.

Captain Small shrugged and smiled.

"You have me there, old chap," he said. "But no doubt, it was so that we wouldn't be able to obtain positive identification of the beggar."

"But how they did it, and where they went, is really the important part," Freddy Farmer said with a frown. Then, looking at Colonel Fraser, he said, "If I may make a suggestion, sir, why not have this whole building searched? There's no telling what you might gather up."

"Ahead of you there, Farmer," the senior officer said. "I have men doing that very thing right now. They are going from floor to floor, and checking up on everybody. They'll be up here to report before long, I expect."

"Do you mind a direct question, sir?" Dawson suddenly asked him.

"Why, no, not at all. Fire away, Dawson."

"About this Karl Stoltz, and Paul von Heimmer, sir," Dave said. "Do you know if your department has ever heard of either of them?"
