"Good!" said Captain Abbey. "'E's beginning to show symptoms of blackmail. I'd send this message on, only we're likely to make a bigger bag by keeping quiet. We'll let 'im 'ave the reply to-morrow morning. What shall we do to 'im next?"

"Shoot him," said Miss Depew with complete calm.

"Oh, I want to 'ave a little fun with 'im first," said Captain Abbey. "I'm afraid you 'aven't got much sense of humor, Miss Depew."

"Do you think so?" she said. She was of the purest Gibson type, and never flickered an innocent eyelash or twisted a corner of her red Cupid's bow of a mouth as she drawled: "I think it would be very humorous indeed to shoot him, now that we know he is a German."

"Well, after 'is trying to leave us without warning 'e deserves to be skinned and stuffed. But we're likely to make much more of it if we keep 'im alive for our entertainment. Besides, 'e's going to be useful on the other side. Now, what do you think of this for a scheme?"

The heads of the conspirators drew closer round the table; and Mr. Neilsen, wandering on deck like a lost spirit, pondered on the tragic ironies of life. The thoughtless laughter that rippled up to him from the captain's cabin filled him with no compassion toward any one but himself. It was merely one more proof that only the Germans took life seriously. All the same, if he could possibly help it, he was not going to let them take his own life.

There was no radiogram for Mr. Neilsen on the following day; and he was perplexed by a new problem as he walked feverishly up and down the promenade deck.

Even if he received an assurance that the Hispaniola would be spared, how could he know that he was being told the truth? Necessity, as he knew quite well, was the mother of murder. It was very necessary, indeed, that his mouth should be sealed. Besides, he had more than a suspicion that his use was fulfilled in the eyes of the German Government, and that they would not be sorry if they could conveniently get rid of him. He possessed a lot of perilous knowledge; and he wished heartily that he didn't. He was tasting, in fact, the inevitable hell of the criminal, which is not that other people distrust him, but that he can trust nobody else.

He leaned over the side of the ship and watched the white foam veining the black water.
