"Not a bit of that, Dot! It's only that I've been so closely associated with these criminals that I'm beginning to see their motives."
"And where does Susie come into all this?"
"The man must have seen her on Soldiers' Camp Island, from his canoe. Or rather, he saw the wrecked autogiro, and knew she must be there."
"And forced her to go with him?"
"Probably. He didn't want to take any chances, leaving her free to help the police."
Linda paused for a moment to eat the salad with which she had been served, and glanced about the dining-room. No one seemed to know her, or notice her—for that she was sincerely thankful.
It was not until they had finished their dinner and found a cool, secluded spot on the veranda, that she went on with her plan.
"What I mean to do," she said quietly, "is to fly back to the camp on Black Jack Island early tomorrow. Not that I expect to find anyone there—but merely to get my direction—to go on to that island in the ocean. I don't know its name, so I couldn't look it up on the map."
"You really expect to catch those two on that island?" asked Dot, excitedly. "Will you take the police along?"
"No! I don't want to tell them a word about all this, except to say that I am going scouting about the country, and to ask for a couple of revolvers.... And, in answer to your first question, I don't really expect to find Susie and the 'Doc' there yet. But I believe they'll be along soon."
