"No, I scarcely noticed the man at all. I was looking at Winkler,
whose behaviour was so peculiar. When he read the card his face
brightened. He read it through once more, then he tore both card
and envelope into little bits and threw the pieces out of the open
window.

"Then he evidently did not want anybody to see the contents of this
note," said a voice from the corner of the room.

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.
