"It is to prevent the current of air running through the tunnel and blowing away the obstruction at this end," said the guide.

"Here it is," said Toza, as he felt down its edge for the bolt.

The bolt drew back easily, and the door opened. The next instant the brigand was pushed rudely into a room, and he heard the bolt thrust back into its place almost simultaneously with the noise of the closing door. For a moment his eyes were dazzled by the light. He was in an apartment blazing with torches held by a dozen men standing about.

In the centre of the room was a block covered with black cloth, and beside it stood a masked executioner resting the corner of a gleaming axe on the black draped block, with his hands crossed over the end of the axe's handle.

"You are just in time!" said the Prince grimly; "we are waiting for you!"

He himself went to bed early and slept soundly, as a man with a good conscience is entitled to do.
