"It must be all right," he thought. "There can't be any trick in all this. It's quite likely that Mortlake does want to play us a mean trick. I can't forget the look he flashed at me the day we took Lieut. Bradbury away from him in that meadow after we had made our first sea trip. Wow!"

Roy could not forbear smiling at the recollection.

They chugged along in silence for some little distance farther, and then the man beside him laid a detaining hand on Roy's arm.

"Almost there now," he said. "Better slow up."

Roy did so. The brakes ground down with a jarring rasp.

"Do you mind getting out?" it said. "We can talk better in the house."

"Where is the house? I don't see one," said Roy, his suspicions rousing a little.
