“Miss Lentz? She is not here. She went in the captain’s boat,” the sub-officer said shortly. “I wish you had gone with her.”

“It was your fault I did not,” said Ruth boldly.

“Perhaps,” admitted the German. “But necessity knows no law, Miss Fielding. It was said you knew too much—or suspected too much. I dislike making a military prisoner of a woman. But, as I said before, necessity knows no law. You and Dowd and Rollife had to be separated from Captain Hastings and the rest of them. There are only a few of us—at present,” he added.

“And how the deuce do you expect to augment your crew?” demanded the chief officer. “You can’t work this ship with so few hands. And you’ve got none of the engineer’s crew.”

“I am something of an engineer myself, Mr. Dowd,” returned the other, smiling with a satisfied air. “We shall have proper assistance before long.” He hailed Krueger, who had climbed to the roof of the radio house. “Is everything all right?”

“Will be shortly, Mr. Boldig,” said the assistant radio man.

Ruth started. Then “Dykman” was “Boldig,” whose name she had formerly heard mentioned between Irma Lentz and the flaxen-haired man. The man with two names turned upon Ruth.

“You had better go immediately to your own room, Miss Fielding,” he said respectfully. “I shall be obliged to lock you in, as I shall Mr. Dowd and Rollife here. I assure you all,” he added significantly, “that it is much against my will that you remain prisoners. I would much rather you had all three gone with the captain.

“By the way, Dowd, Captain Hastings was told you were in command of this small motor launch. I am afraid you will have much to explain, later. And you, too, Rollife.”

Rollife only growled in reply and Dowd said nothing. When they started aft with Boldig, Ruth followed. She knew it was useless to object to any plan the German might have in mind.
