Jack noted that the murmurous sound which they had decided must be the mingling of voices, had suddenly stopped. From this he imagined that those within the closed cabin of the power boat had heard the splash and were waiting for a repetition of the same, in order to gauge its meaning.
Would they come out to investigate? If so, what should be the programme of the three who stood there in the water? None of them had ever fired a shot at a human being in all their lives; and the mere thought of such a thing was distasteful to them. At the same time, if their comrade were in the hands of unscrupulous men, and heroic measures had to be adopted in order to effect his release, not one of them would hesitate.
Jack often looked back to that strained moment, when he and his comrades stood there, knee deep in the lagoon, within a dozen feet of the mysterious little power boat, keyed up to a condition when their nerves were all on edge, and waiting for whatever might happen. He could feel a sense of amusement over it, too, at some future time; but it was certainly no laughing matter then.
Then there suddenly flashed out a broad beam of light. The door of the cabin had been opened; and, as those standing there in the water were directly behind the stern, the light fell full upon them.
Jack saw a figure push into view. Outlined against the lighted interior of the boat it stood up in plain sight, and they could even make out the fact that the unknown party wore knickerbockers, as though dressed for an outing.
Of course he must have discovered the threatening trio there just as soon as he thus partly emerged from the cabin. They could tell this from the way in which he stood as if riveted to the spot, making no motion either to advance further, or retreat back into the recesses of the boat’s interior.
Jack did not mean to give him a chance to take the initiative. He raised his gun, and immediately covered the unknown party; which action was accepted as proof by his two chums that they were to follow suit, and they proceeded to do so.
If astonishment had held the man motionless up to this moment, a due sense of caution kept him so after he discovered those three menacing guns turned full in his direction. Apparently he must be either stunned by the situation that had burst upon him without warning; or else he kept his head, and knew there was only one thing to do in order to avoid trouble, which was to submit to the inevitable.
“Don’t think of trying to drop back into that cabin,” said Jack, in a voice that was quite stern, even if it did quiver a little; “we’ve got you covered all right, and you might as well surrender!”
