"I think not!" Delora said.

There was an instant's silence. I looked at Delora and wondered what he meant. He looked at me as a man looks at his enemy.

"May I ask how you intend to prevent me?" I inquired.

"Easily!" he answered, with a slight sneer. "There are four men in this house who will obey my bidding. There are also five modes of exit, two of which lead into the river."

"I congratulate you," I said, "upon the possession of such a unique lodging-house."

Delora sighed.

"I can assure you," he said, "that it is more expensive than the finest suite in the Milan. Still, what would you have? When one has friends who are too curious, one must receive them in a fitting lodging."

"You are a very brave man, Mr. Delora," I said.

"Indeed!" he answered dryly. "I should have thought that the bravery had lain in another direction!"

I shook my head.
