"Is that so?" remarked Alwyn. "I was under the impression that Strogoff was sent on board the Malfilio."

"He was aboard the old Donibristle yesterday, at any rate," declared the skipper. "Miles knows about Miss Vivian, and, although I cannot say definitely, I think he's the sort of man who wouldn't hesitate to give the show away if he could make his own case good."

The seriousness of Captain Blair's words took Burgoyne aback. The Third Officer remembered that little incident of the chocolate. It was but a straw that showed the direction of the wind. Miles had proved himself to be a man of no moral fibre. To what depths would he descend to obtain consideration from the villainous Strogoff?

"That is why you wanted the boat held in readiness, sir," he asked. "To remove Miss Vivian from the island in the event of discovery?"

"You've hit it, Mr. Burgoyne. The sooner the preparations are completed the better; but, of course, there may be no necessity for them. I quite agree with you that Minalto is the right man for the job, with you in charge of the boat."

"And Colonel Vivian."

"He won't be going," declared the skipper. "I pointed out to him the almost unsurmountable disadvantages of having a cripple in the boat. His health, too, isn't at all good. He quite saw the force of my contention."

"We are speaking, sir, as if the lifeboat were already in our possession."

"Aye," rejoined the Old Man. "It's a rough proposition, Mr. Burgoyne, but from what you've told me the task is not beyond your ingenuity."

That night Burgoyne carefully revised the altered situation. The perplexing factor in the case was the uncertainty of the time when the boat might be required. He could not completely grasp the meaning of Captain Blair's decision to refrain from action until Miss Vivian was in immediate danger. It was obvious that the boat must be seized, taken to the western side of the harbour, and provisioned all within a few hours, and be out of sight before dawn. There wasn't the faintest hope of being able to conceal the boat for several days prior to the dash for freedom. The mere fact that the lifeboat had been removed from the beach would be sufficient to put the pirates on the qui vive.
