d Craig simply. "I will try to think it
out in detail to-night. Where can I find you to-morrow?"

"Come to me at the opera-house in the afternoon, or if you want me
sooner at Mr. Cesare's residence. Good night, and a thousand thanks to
you, Professor Kennedy, and to you, also, Mr. Jameson. I trust you
absolutely because Luigi trusts you."

We sat in the little dining-room until we heard the door of the
limousine bang shut and the car shoot off with the rattle of the
changing gears.

"One more question, Luigi," said Craig as the door opened again. "I have
never been on that block in Mulberry Street where this Albano's is. Do
you happen to know any of the shopkeepers on it or near it?"

"I have a cousin who has a drug store on the corner below Albano's, on
the same side of the street."

"Good! Do you think he would let me use his store for a few minutes

thanks for thinking of me in connection with this case. I've enjoyed
Signor Gennaro's singing often enough at the opera to want to render him

mind."

A little before nine the following day Kennedy and I dropped into
Luigi's again. Kennedy was carrying a suitcase which he had taken over
from his laboratory to our rooms the night before. Luigi was waiting for
us, and without losing a minute we sallied forth.

By means of the tortuous twists of streets in old Greenwich village we
came out at last on Bleecker Street and began walking east amid the
hurly-burly of races of lower New York. We had not quite reached
Mulberry Street when our attention was attracted by a large crowd on one
of the busy corners, held back by a cordon of police who were
endeavouring to keep the people moving with that burly good nature which
the six-foot Irish policeman displays toward the five-foot
burden-bearers of southern and eastern Europe who throng New York.

Apparently, we saw, as we edged up into the front of the crowd, here was
a building whose whole front had literally been torn off and wrecked.
The thick plate-glass of the windows was smashed to a mass of greenish
splinters on the sidewalk, while the windows of the up
