It was quite dark. But the detective knew where the bed was, and he moved over to it without hesitation. Then he uttered a low exclamation of surprise.

The bed was empty!

“Hurry, Chick! Let’s get out of this! There’s something going to happen. They’ve found out that I have got away!”

“Where’s the other cabin?”

“Farther along! Let me see!”

Nick rushed forward. He was not astonished when he found that the other cabin was not only unoccupied, but that the door was unlocked and partly open.

“Let’s get out, Chick! I guess the whole yacht is on the qui vive! The rascals have laid a trap for us.”

“Do you think they know I am aboard?”

“I hope not! That will give us an advantage if we can surprise them by being two, instead of one. Come on!”

Nick led the way to the short flight of steps leading to the big door that gave upon the deck.
