"How?"

"Through the next room, which must be the dressing-room. They've left the window open, no doubt to give the prince a little air."

"But I should want a ladder . . ."

"There's one hanging on the wall of the coach-house. Shall I get it for you?"

"Yes, do," said Paul eagerly. "Be quick."

A whole new scheme was taking shape in his mind, similar in some respects to his first plan of campaign and likely, he thought, to lead to a successful issue.

He made certain that the approaches to the villa on either side were deserted and that none of the soldiers on guard had moved away from the front-door. Then, when Bernard was back, he placed the ladder in position and leant it against the wall. They went up.

The open window belonged, as they expected, to the dressing-room and the light from the bedroom showed through the open door. Not a sound came from that other room except a loud snoring. Paul put his head through the doorway.

Prince Conrad was lying fast asleep across his bed, like a loose-jointed doll, clad in his uniform, the front of which was covered with stains. He was sleeping so soundly that Paul was able to examine the room at his ease. There was a sort of little lobby between it and the passage, with a door at either end. He locked and bolted both doors, so that they were now alone with Prince Conrad, while it was impossible for them to be heard from the outside.

"Come on," said Paul, when they had apportioned the work to be done.
