Half a dozen policemen threw themselves against the door; but it withstood their weight, and the locks within only yielded after repeated trials. Then the door flew open, and all entered the hallway, closing it behind them.

The next door then confronted them, but Will pointed out the panel, and a club smashed that in, when Captain Daly put in his hand and drew back the bolt.

"This is a secure nest, that is certain; but I fear we'll find it deserted," said Captain Daly, and with their lantern-shades raised, they hastily followed Will up the stairs.

He went directly to the door by which he had entered, and the panel was opened with a club, and the officers dashed in, and throwing themselves against the inner door it yielded to their weight with a crash.

Then they found themselves in the large living room of the band, from whence Will had made his escape.

The bunks were there, the table, chairs, dumb-waiter, and much clothing and bedding was scattered about, showing a hasty departure; but not a soul was present.

"Will you follow down the chimney, sir?" asked Will.

"Yes, I will follow with several of my men, while the remainder break in every door of this nest, which is, indeed, a safe retreat.

"Come, men, I want only those who have cool heads on lofty places to go, for, from what he told me, it will require all your nerve to follow him."

Four of the officers volunteered, and up the ladder went Will, he having in the meantime recovered his hat, shoes and jacket from the floor.
