“It is one of your passengers,” answered Jack. “We have captured your vessel and part of your crew has been left behind, having landed on the island. The rest is below with you.”

“But who are you, and what does this mean?” demanded the bewildered captain.

“Just what we told you we are, two American boys who are looking for some one who is with the Allies at the Dardanelles,” Jack explained.

“Why have you done this?” continued the prisoner of the hold.

“Because we believed you meant us harm, and we decided to strike first. So I made the smudge below in order to cause the crew to leap overboard and abandon the craft. But you were too brave a man to be frightened, and we had to shut you down below or lose the game. I want to make a bargain with you, Captain.”

The man waited some little time before replying. Evidently he was trying to get a firm grip on the conditions by which he was surrounded, so that he could play his best card. Then he called out again as though in anger.

“Do you know what I have a good mind to do, boy? I have matches with me here, and the powder can be easily reached. One match would be enough to finish us all, and we could go into glory together.”

“I understand that, Captain,” said Jack, coolly, as though not a bit afraid the other would put his threat into execution. “We are willing to take our chances. You would be a fool to end your life that way when you can live to enjoy other exploits.”

“But if I fall into the hands of the British they will surely shoot me!” urged the man below.

“I give you my word of honor that they will let you and your men go free, on condition that you do nothing to injure the boat or the cargo. Is it a bargain, Captain Zenos? We are both armed, and will hesitate at nothing, even should you succeed in breaking loose, which we do not mean to have happen. Be reasonable, and, after all, you will lose only your boat. There are other craft to be had for money, but no one can get a second life, you know, if he loses the one he has.”
