“Was I?” asked Tom, brightening. There had been reason enough for his scowl.

“Randolph isn’t here, so I can’t take Mr. Tremaine to him. Confound the luck. Off we go to Tampa, and the mystery of the vanished money isn’t cleared up. I wouldn’t attempt to tell Mr. Tremaine without being backed by Officer Randolph or a letter from him. As for going up to that other town, and getting confirmation from Randolph’s elder son, that would be out of the question. The young man wouldn’t say a word about the express company’s business, unless he had orders from his father. And Randolph is away, heaven alone knowing when he’ll be back here. Oh, I hope Randolph also left a note for Mr. Tremaine. But no such luck!”

No wonder Tom Halstead was agitated as he paced the deck from bow to stern. As long as the mystery of the vanished money remained not cleared up he would never feel easy about the stain that it left clinging to Joe and himself—principally to himself.

The boat was coming out again from shore.

“Everybody in it except Dixon,” discovered Halstead, with a start. “I wonder if that fellow has made an excuse to get away? Has he fled? Yet that doesn’t seem just likely, either, after all the attention he showed Ida Silsbee on the way down from Lake Okeechobee. I guess he figures that, if he can once marry Tremaine’s ward, then, no matter what leaks out, Tremaine will keep silent for Ida Silsbee’s sake.”

The boat was soon alongside.

“One passenger shy,” hailed Halstead, forcing himself to laugh lightly.

“Yes,” nodded Henry Tremaine, indifferently. “Dixon happened to think, at the last moment, to go up to the post office, to see if there was any mail for any of our party. Very thoughtful of the young man. We’ll send the boat ashore for him, and he’ll be out here on the next trip.”

Tom Halstead watched the shore closely enough, after that. However, at last, he had the satisfaction of seeing Oliver Dixon wave his hand from the landing stage, and then embark in the rowboat.

“Any mail, Oliver?” asked Mr. Tremaine, as the young man stepped up over the side.
