"I say, you fellows, I think I'll go on deck and see what's doing," announced Sub-lieutenant Stirling.

His companions looked at him with feelings akin to amazement.

"What the deuce are you babbling about, old man?" asked O'Hara. "You know as well as we do that we are locked in."

None of the three prisoners had any thought of turning in. They had heard the crash of the British shells as the cruiser sought to wing the German raider. In spite of the danger of being hit, and what was infinitely worse, being drowned like rats in a trap in a foundering vessel—since it was more than possible that the crew of the Pelikan would take no steps to liberate the captives—the subs were in high spirits. They took it for granted that their release would be a matter of a few minutes only, since the lightly-built Pelikan would stand no earthly chance against the vastly-superior ordnance of the pursuing vessel. Then came a sudden cessation of the firing; yet the prisoners knew by the thud of the engines that the German ship was still pelting on her bid for safety.

Hours passed. There was no doubt in the minds of the three men that the Pelikan was being hotly pursued. The pulsations of the engines under forced draught was conclusive evidence on that point. The captive officers sat and talked, drawing conclusions as to what was taking place, until Stirling suddenly hurled a verbal bomb-shell by announcing his intention of going on deck.

"Don't be so rash with your assertions, Pat," replied Stirling in mock reproof. "It is certainly true that we are locked in. It is also a fact that I possess a very efficient screw-driver. I took the liberty of annexing it, as one of the carpenter's crew has been guilty of negligence. On board a British ship that screw-driver would, in the usual course of routine, find itself in the scran-bag; but since I'm not at all certain that such a visible cure for forgetfulness exists in the German navy, I have and hold the article in question."

"No need to brag about it, old man," said O'Hara. "You are not the only light-fingered gentleman of our little coterie. As these Germans had no compunction in entering the cabin and sneaking out hard-earned cash, I repaid the compliment by entering one of the officer's cabins, and this is what I annexed."

He held up a dark-green paper packet containing a dozen rounds of ammunition that fitted the automatic pistol.

"Steady!" exclaimed Denbigh. "You're looking for trouble with that thing, Pat. It's as dangerous as a shillelagh at Donnybrook Fair. And what's the object in breaking out?" he continued, addressing Stirling, who was fondling the screw-driver in anticipation. "If you're detected there'll be a rumpus. I don't suppose you'll do any good, and if you possess your soul in patience a little longer you'll be let out."

"Hanged if I can," retorted Stirling. "I must have a look round. I didn't ask you fellows to come. In fact, there's less risk for one than three."
