"All set, Mapes," it said sharply. "Come on down. You finished the job?"
"Ay, ay, sir," the answer gruff, but with a tinge of excitement in the tone. "She's fixed all right. Hold hard, now, mate."
West, thoroughly aroused, realizing instantly the importance of this new move, and as quickly suspecting its purpose, leaped to the port-hole, and, endeavoured to gain a glimpse without. The night was still intensely black, the sky overcast and starless, the only glimmer of light the reflecting of foam tipped surges. If land was near it remained invisible, nor could he even be sure of the close proximity of a boat. There seemed to be a smudge there at the left, a black, lumping shadow, shapeless against the background of sea; yet he could not be sure. Even as he gazed at it doubtfully, the dim object disappeared, fading away like a mirage. No sound reached him to cause the vision to seem real--no voice, no creak of oars, no flap of a sail; yet something told him that mysterious shadow was a boat, a boat filled with men, creeping away silently into the night, fleeing from the yacht, and vanishing into the darkness.
My God, what could such action mean? Why were these fellows deserting the Seminole, leaving him helpless aboard, locked into that stateroom? Was the yacht disabled? sinking? and had they merely forgotten him in their own eagerness to escape? Were they in mid-lake? or close to some point of land? Had every one gone, leaving the vessel totally abandoned, a wreck buffeted by the surges, doomed to go down, unseen, its final fate unknown? Unknown! The word rising to his brain was the answer. There was the crest of the plot. What could be easier, or safer, than this ending? Who would ever know the truth? Who could ever prove anything, even if they suspected? And who was there to suspect?
No one had reason to believe he was aboard the Seminole; not even McAdams. If it was to their interest to get him permanently out of the way--if Hobart had so decided--what simpler method could be found than the sinking of the yacht? The very crew might be innocent of the purpose, dupes of the conspiracy; they might even be unaware of his presence aboard, and deceived by Hogan into the belief that the vessel had opened a seam, and must sink shortly, would take to the boat without suspecting any one was left behind. They could so testify in all honesty if any question ever arose. The very simplicity of the scheme meant safety; yet the possibility of such cold blooded murder had never before occurred to him. Unknown! without a trace left; only a boat crew landing somewhere on the coast at dawn, and scattering to the four winds. It was a plot infernal.
