At length, some time after night-fall, a low knock came to the street-door. No attention being paid to it, the knock was repeated, and this time it was rather louder. It echoed through the house, but no one stirred. After a short interval, as if the person outside had been listening and had satisfied himself, a slight rattling was heard at the keyhole, and, the lock being picked, the footsteps of two men were heard in the passage.

They quietly bolted the door after them, and pulling from beneath their coats a couple of dark lanterns, walked softly up stairs. Finding the door of the front-room locked, they came down again, and tried the front-parlour, which was also locked, whereat, Mr. Trott, who was listening with his ear close to the handle, laughed immoderately, but without noise.

Unsuccessful in these two attempts, they went down stairs, and with some surprise found one of the kitchens locked, and the other open. Only stopping just to peep into the open one, they once more ascended to the passage.

"Well," said one of the men, as he came up the kitchen stairs, "we have got it all to ourselves to-night, anyway, so we had better not lose any time. Hollo!"—

"What's the matter?" said the other, looking back.

"Look here!" rejoined his comrade, pointing to the garden-door, with the bolts, and iron plates, and patent locks,—"here's protection—here's security for a friend. These have been put on since we were here afore; we might have tried to get in for everlasting."

"We had better stick it open," said the other man, "and then if there's any game in front, we can get off as we did t'other night."

"Easily said. How do you do it?" said the first speaker, "it will take no end of time, and make no end of noise, to undo all these things. We had better look sharp. There's no rehearsal to-night, remember."

At this, they both laughed, and determining to take the front-parlour first, picked the lock without more ado. This done, they pushed against the door to open it, but were unable to do so by reason of the bolts inside, which Mr. Trott had taken good care to thrust into the staples as far as they would possibly go.
