Quickly he pushed row after row of bricks into the next house until he had cleared an opening four feet square.
"Come along," he said to the Duke, and disappeared feet foremost through the opening.
The Duke mounted the steps, and found himself looking into a large empty room of the exact size and shape of the drawing-room of M.
Gournay-Martin, save that it had an ordinary modern fireplace instead of one of the antique pattern of that in which he stood.

Its chimney-piece was a few inches below the opening.

He stepped out on to the chimney-piece and dropped lightly to the floor.
"Well," he said, looking back at the opening through which he had come.
"That's an ingenious dodge." "Oh, it's common enough," said Guerchard.

"Robberies at the big jewellers' are sometimes worked by these means.

But what is uncommon about it, and what at first sight put me off the track, is that these burglars had the cheek to pierce the wall with an opening large enough to enable them to remove the furniture of a house." "It's true," said the Duke.
