A strange and mysterious proceeding then took place.

The person in the fustian coat approached the chimney, and applied a small turnscrew, which he took from his pocket, to a screw in the iron frame-work of the rusty grate. In a few moments he was enabled to remove the entire grate with his hands; a square aperture of considerable dimensions was then revealed. Into this place the two men thrust the parcels which they had taken from their pockets: the grate was replaced, the screws were fastened once more, and the work of concealment was complete.

The one in the gabardine then advanced towards that portion of the wall which was between the two windows; and the youth in the adjoining room now observed for the first time that the shutters of those windows were closed, and that coarse brown paper had been pasted all over the chinks and joints. Dick applied his hand in a peculiar manner to the part of the wall just alluded to, and a sliding panel immediately revealed a capacious cupboard. Thence the two men took food of by no means a coarse description, glasses, pipes, and tobacco; and, having hermetically closed the recess once more, seated themselves at the table to partake of the good cheer thus mysteriously supplied.

The alarm of the poor youth in the next chamber, as he contemplated these extraordinary proceedings, may be better conceived than depicted. His common sense told him that he was in the den of lawless thieves—perhaps murderers; in a house abounding with the secret means of concealing every kind of infamy. His eyes wandered away from the little window that had enabled him to observe the above-described proceedings, and glanced fearfully around the room in which he was concealed. He almost expected to see the very floor open beneath his feet. He looked down mechanically as this idea flitted through his imagination; and to his horror and dismay he beheld a trap-door in the floor. There was no mistaking it: there it was—about three feet long and two broad, and a little sunken beneath the level of its frame-work.

Near the edge of the trap-door lay an object which also attracted the youth's attention and added to his fears. It was a knife with a long blade pointed like a dagger. About three inches of this blade was covered with a peculiar rust: the youth shuddered; could it be human blood that had stained that instrument of death?

Every circumstance, however trivial, aided, in such a place as that, to arouse or confirm the worst fears, the most horrible suspicions.

The voices of the two men in the next room fell upon the youth's ear; and, perceiving that escape was still impracticable, he determined to gratify that curiosity which was commingled with his fears.

"Well, now, about this t'other job, Dick?" said Bill.

"It's Jem as started it," was the reply. "But he told me all about it, and so we may as well talk it over. It's up Islington way—up there between Kentish Town and Lower Holloway."

"Who's crib is it?"
