"Well, I'm glad to be back along with you," he said.

"I don't imagine you'll be glad to be back very long," said Jack dryly. "It seems to me you might as well have stayed where you were. The result probably will be the same. Only this time you'll have to face a British court martial and they'll probably hang you."

"While there's life there's hope," Davis spoke sententiously. "Which is the reason I didn't say anything over there."

He waved his hand in the general direction of the German submarine they had so recently left.

"Well, I'm much obliged, I'm sure," said Frank. "If you had spoken when you recognized Lord Hastings, it would have been all off with all of us. However, I'm afraid I shall be unable to speak a word in your behalf."

Davis shrugged his shoulders and turned away as Lord Hastings approached.

"Below with you all, quick!" exclaimed the latter. "Don't you realize you are prisoners? What do you suppose some of these German officers would say if they saw you making so free of this vessel, eh? They'd probably come over to see what is wrong. Get below!"

Lord Hastings spoke gruffly, for he had risked much to assure their safety and he did not wish his plans to go for naught. Frank, Jack and Davis obeyed without a word.

"Now," said Lord Hastings when all were safely below, "we'll have to get away from here."

"There should be no trouble about that," said Frank. "All we have to do is submerge and move off."
