At once the whole affair was made plain to Trask. The dinghy, which had been lowered from the after davits when the Nuestra anchored, was being stolen! The crew were pulling it forward by the line which the man had taken aft, and this man was keeping the boat clear of the schooner's side. The line evidently had been made fast to the dinghy's painter.
Here, indeed, was something which gave every appearance of being underhand work. With the Golden Isle only a few hundred yards distant, and all hands to go ashore in the morning, there could be no other reason for stealing the dinghy than a plan to visit the island under cover of darkness. The plan foreshadowed treachery. The crew sought some knowledge which they wanted before the other members of the expedition could be aware of conditions on the island.
Trask saw at once the purpose of the crew, although he had no way of knowing how they intended to gain any advantage to themselves unless they contemplated abandoning the Nuestra, or destroying it and those remaining aboard. He had no doubt the scheme was to learn whether or not there was gold, and so to act, in the event they found it in great quantities, that they would be assured of having it for themselves.
It was a wild idea, this going out in the night to hunt gold. But it was plain that the cupidity of the crew had been aroused by the prospect of a shining, yellow beach. But what was to Trask far more important, and fraught with danger to Marjorie, Locke, Dinshaw, Jarrow, and himself, was the knowledge that Peth, if not the leader of the enterprise, at least must be aware of what was taking place.
The rain came on now with steady, monotonous force, turning the sea into a boiling cauldron. Trask, drenched in the first minutes of the downpour, remained where he was, crouching under the bulwark with his head high enough to get the bulwark forward against the gray luminosity of the beaten water.
So concealed, if it could be called concealment, in the darkness of the schooner, he saw four figures go over the side, and heard them fumbling in the dinghy. They pushed off gently and rowed away in the direction of the island, amid the muffled click of oars. Before proceeding but a few yards the boat was lost to him in the welter of steaming water and all-enveloping blackness.
Trask suffered from a chill, but he remained where he was, wondering what could, or should, be done. Jarrow must be warned. The sky now turned lighter, being relieved of its burdened clouds, and the rain began to fall off, until it was merely a gentle trickle.
Dripping like a water spaniel returning to the shore, Trask turned in to the door of the main cabin, planning to rid himself of his wet clothing, get into some dry garments, and call Jarrow.
As he felt his way into the deeper gloom he heard a movement close at hand, and stopped, leaning against the bulkhead, just abaft of the galley. He saw that the light from outside marked the cabin door as a great rectangle in which a moving form could easily be seen from the inside.
"Who's that?" came a whisper.
