when she was left alone for a few minutes
while Pokorny went in to see the commissioner. But as soon as his errand
was known, both the bookkeeper and his companion were led into the
office of Head Commissioner Dr. von Riedau, who had charge of the
Hietzing murder case.

When Dr. von Riedau heard the reason of their coming, his interest was
immediately aroused, and he pulled a chair to his side for the little
thin man with whom he had been talking when the two strangers were
ushered in.

"Then you believe you could identify the murdered man?" asked the
commissioner.

"From the general description and the initials on his linen, I believe
it must be Leopold Winkler," answered Pokorny. "Mrs. Klingmayer has not
seen him since Monday morning, nor has she had any message from him. He
left the office Monday afternoon at 6 o'clock and that was the last time
that we saw him. The only thing that makes me doubt his identity is that

be wasting his talents which we need for more difficult problems. If you
or any one else have anything to tell us, it must be told only to me
or to Muller. And before you leave to look at the body, I would like
to know whether the dead man owned a watch, or rather whether he had it
with him on the day of the murder."

"Yes, sir; he did have a watch, a gold watch," answered Mrs. Klingmayer.

Riedau looked at the bookkeeper, who nodded and said: "Yes, sir; Winkler
had a watch, a gold watch with a double case. It was a large watch, very
thick. I happen to have noticed it by chance and also I happen to know
that he had not had the watch for very long."

"Can you tell us anything more about the watch?" asked the commissioner
of the landlady.

"Yes, sir; the
