“I don’t think so, that is except the one underneath. We made a pretty careful search, but I suppose it’s possible that we missed it,” Bob said.

“Do you know where this shack or cave is, Mr. Kane?” the detective asked.

“Sure I do. I’ve been there a half dozen times more or less.”

“Then I reckon we might as well be on our way.”

“How about letting us go along?” Jack asked.

“Nothin’ doing,” the detective shook his head decidedly. “It’s too risky. You see, son, that fellow’s a bad one and if he sees you he’ll think you put us on to him and he’ll get you if he can. No, I’ve got plenty of help and it wouldn’t be right to let you take the risk.”

“He’s right, Bob,” the sheriff added. “We don’t need you and there’s no sense in running into danger just for the fun of the thing. If you should go and anything should happen to either of you I’d never be able to face your father or mother again.”

Seeing that the men were determined the boys said no more on the subject but wished them good luck as they pushed off.

“Just the same I’d liked to have gone along,” Jack complained as they stood on the end of the wharf and watched the boat disappear around the point.

“Same here, but I guess they were right about it,” Bob said more cheerfully. “At any rate those fellows aren’t the ghost we’re after and it’s up to us to stay on the job here.”
