sorry for her husband.
Now there's a young couple with everything in the world to make them
happy and so fond of each other, and the poor little lady has to be so
sick."

"They are very happy, you say?" asked Muller carelessly. He had no
particular set purpose in following up this inquiry, none but his usual
understanding of the fact that a man in his business can never amass too
much knowledge, and that it will sometimes happen that a chance bit of
information comes in very handy.

The landlord was pleased at the encouragement and continued: "Indeed
they are very happy. They've only been married two years. The lady comes
from a distance, from Graz. Her father is an army officer I believe, and
I don't think she was over-rich. But she's a very sweet-looking lady and
her rich husband is very fond of her, any one can see that."

"You said just now that they had gone away, where have they gone to?"

the detective's hand under his loose overcoat. Muller's visit to Venice,
like most of his journeyings, had been one of business. This time to
capture and bring home a notorious and long sought embezzler. He did
not volunteer any of this information, however, but merely asked in
a politely interested manner whether the landlord himself had been to
Venice.

"Yes, indeed," replied the latter proudly. "I was head waiter at Baner's
for two years."

"Then you must make me some Italian dishes soon," said Muller. Further
conversation was interrupted by the entrance of Franz, the old butler of
the house opposite.

"Excuse me, sir; I must get him his glass of wine," said the landlord,
hurrying away to the bar. He returned in a moment with a small bottle
and a glass and set it down on Muller's table.

"You
