Fritz Bormann looked around astonished and rather doubtful at the little man who had risen from his chair and now came forward. Without waiting for an answer from the clerk, the other continued: “Did Winkler have money sent him frequently?”

Bormann looked inquiringly at the commissioner, who replied with a smile: “You may answer. Answer anything that Mr. Muller has to ask of you, as he is in charge of this case.”

“As far as I can remember, it happened three times,” was Bormann’s answer.

“How close together?”

“Why—about once in every three or four months, I think.”

“That looks almost like a regular income,” exclaimed Riedau. His eyes met Muller’s, which were lit up in sudden fire. “Well, what are you thinking of?” asked the commissioner.

“A woman,” answered Muller; and continued more as if thinking aloud than as if addressing the others: “Winkler was a good-looking man. Might he not have had a rich love somewhere? Might not the money have come from her, the money that was found in his pocket?” Muller’s voice trailed off into indistinctness at the last words, and the fire died out of his eyes. Then he laughed aloud.

The commissioner smiled also, a good-natured smile, such as one would give to a child who has been over-eager. “It doesn’t matter to us where the money came from. All that matters here is where the bullet came from—the bullet which prevented his enjoying this money. And it is of more interest to us to find out who robbed him of his life and his property, rather than the source from which this property came.”

The commissioner’s tone was friendly, but Muller’s face flushed red, and his head dropped. Riedau turned to Bormann and continued: “And because it is of no interest to us where his money came from—for it can have nothing whatever to do with his murder and the subsequent robbery—therefore what you noticed of his behaviour cannot be of any importance or bearing in the case in any way. Unless, indeed, you should find out anything more. But we appreciate the thoughtfulness of yourself and your employer and your readiness to help us.”

Bormann rose to leave, but the commissioner put out a hand to stop him. “A few moments more, please; you may know of something else that will be of assistance to us. We have heard that Winkler boasted of his belongings —did he talk about his private affairs in any way?”
