Now, as he watched the sun glinting on the waves between the point and Garden Island, where his motorboat had gone down, he reconstructed in the light of his present knowledge what had taken place there yesterday morning. He was quite certain, now, that he recalled seeing that little pennant of canvas sticking out from the water. Those two recklessly pursuing men from St. James must have seen it also, as they drove down upon him. Then, when he had vanished in the rain to leeward, when after his two shots they probably thought him dead or drowning, they had put back for that fish-trap flag. Why? Not because it marked a fish-trap alone, but because it marked something else of which they knew. And, drawing down upon that little flag, had been a third craft, unsuspected in the obscurity. “They broke off the flag, were probably fishing up the trap, when the other chaps appeared and opened fire. Then what? The chances are a thousand to one that the murderers didn’t wait to get what they had come for. One doesn’t shoot down a couple of men and then stick around long. Besides, the flag was gone, and there were heavy rollers running, and the sheets of rain obscured everything. They couldn’t hope to find the trap again in all that muck; they’d have to go away and come back in good weather, when they might locate the spot by means of landmarks and bearings from shore. Therefore, if my theory is correct, if they’re really whisky-runners and that little flag marked a stock of whisky as well as a fish-trap--all I have to do is to wait. No boat has been up this way all morning. Either I’d have seen it, or Nelly would have seen it and remembered about it.” Conviction grew upon him that he had the right steer by the tail. Fishermen would not be apt to open deadly fire, even if they caught other men robbing their traps; but liquor-runners take no chances. Again he was impressed with the absolutely ideal situation of the islands--many, like that on which he now lay, uninhabited. East-coast fishermen could bring in the stuff from the Canadian side and plant it, and go away again. Other fishermen from the adjacent mainland, from the upper peninsula, from the Wisconsin shore, could come and get it. Who would suspect? And if anyone did suspect, as Nelly Callahan had said, the island men would get the blame. The Beavers had a reputation for turbulency which was less justified than forced upon them. The afternoon hours waned, and the sun sank, and nothing happened. Nothing broke the horizon save the big green-and-white fishboat belonging to the three Danes, coming in from the north and heading for the settlement on Garden Island, with a swarm of gulls wheeling and trailing behind her to tell of fish being gutted and nets being washed. She vanished, and Hardrock rose stiffly, went to his canoe, shoved out and paddled around the point.
