"There are, then, three ways," said Lemage. "We may break into the front room from here, or from the room where is m'sieur your colleague. There is, no doubt, a door corresponding to this one. The other way is to go in by the window of that front room, for I have made the observation that its other window, that opens on the old drive to the east, is barred most heavily. Do I accord with the views of m'sieur?"
"Quite," said Sheffield crisply. "We'll work through the front window. Hullo, Harborne!"
"Hullo!" came the latter's voice from the next room.
"Nobody in there?"
"No. Empty room. Door's locked. What's up on your side?"
"Nothing. Mr. Lemage has joined us. Stand by for squalls. I'm going round to get in at the front-room window."
He paused and listened. They all listened.
