given yourselves away. Who but a German spy would be here seeking word
of the vanishing submarines?"

"But I tell you----" began Jack.

"Silence," thundered the officer. "You have betrayed yourselves, and
that is enough. I give you my word you shall be shot in the morning."

"Oh, I guess not," replied Frank with a laugh. "I guess Lord Hastings
will be able to get us out of this mess."

"Lord Hastings?"

"Why, yes, we happen to serve under him; that's all."

"Tell it to the marines," replied the man with sarcasm. "I am not asking
you to admit anything, for I know enough now."

"Oh, all right," said Frank.

"Climb into my boat," ordered their captor.

The lads complied.

"Say," said Frank, "this is Lord Hastings' motorboat. He told us not to
lose it. Tie it on behind and pull it along, will you?"

"We'll pull it along all right," replied their captor. "Now the best
thing you fellows can do is to keep quiet."
