“I’ll go back for it. You fellows keep right on,” he said.

“Where shall we meet you? We’re bound for the hospital,” said Ralph.

“Where from there?”

“To the Western Union offices.”

“And then?”

“Why, I guess to the police station or whatever answers to it over on this side. I’ve a burning desire to lay the facts in the case before the authorities.”

“Very well then, I’ll meet you at the telegraph office.”

And so it was arranged. While Percy and Ralph hastened to the hospital, which lay at one end of the town, Harry made the best of his way back toward the River Swallow. His conscience hurt him a bit for not having told his friends the true reason for his return to the motor craft.

Harry was not in search of something forgotten.

He was on the trail of the third man who, despite all evidence to the contrary, he was still firmly convinced was concealed somewhere on board the River Swallow.
