Hilliard was not long in slipping back to his former position at the porthole.

“By Jove!” Bulla was saying. “And to think that two years ago I was working a little coaster at twenty quid a month! And you, Coburn; two years ago you weren’t much better fixed, if as well, eh?”

Coburn ignored the question.

“It’s good, but it’s not good enough,” he declared. “This thing can’t run for ever. If we go on too long somebody will tumble to it. What we want is to try to get our piles made and close it down before anything happens. We ought to have that other ship running. We could double our income with another ship and another depot. And Swansea seems to me the place.”

“Bulla and I were just talking of that before you came aboard,” the captain answered. “You know we have considered that again and again, and we have always come to the conclusion that we are pushing the thing strongly enough.”

“Our organization has improved since then. We can do more now with less risk. It ought to be reconsidered. Will you go into the thing, skipper?”

“Certainly. I’ll bring it before our next meeting. But I won’t promise to vote for it. In our business it’s not difficult to kill the goose, etcetera.”

The talk drifted to other matters, while Hilliard, thrilled to the marrow, remained crouching motionless beneath the porthole, concentrating all his attention on the conversation in the hope of catching some word or phrase which might throw further light on the mysterious enterprise under discussion. While the affair itself was being spoken of he had almost ceased to be aware of his surroundings, so eagerly had he listened to what was being said, but now that the talk had turned to more ordinary subjects he began more or less subconsciously to take stock of his own position.

He realized in the first place that he was in very real danger. A quick movement either of the men in the cabin or of some member of the crew might lead to his discovery, and he had the uncomfortable feeling that he might pay the forfeit for his curiosity with his life. He could imagine the manner in which the “accident” would be staged. Doubtless his body, showing all the appearance of death from drowning, would be found in the river with alongside it the upturned boat as evidence of the cause of the disaster.

And if he should die, his secret would die with him. Should he not then be content with what he had learned and clear out while he could, so as to ensure his knowledge being preserved? He felt that he ought, and yet the desire to remain in the hope of doing still better was overpowering. But as he hesitated the power of choice was taken away. The men in the cabin were making a move. Coburn finished his whisky, and he and Henri rose to their feet.
