Benito nodded, blowing a ring of smoke toward the ceiling. “They must have suspected that we’d be out after them before long. They won’t dare to go away from the island while we have the brother, and they will be on the lookout. Soon as Marcy comes back we’ll go after the other two.”

Jim felt his blood chill as the facts of the case came to him. The men had Don and were coming to take Terry and himself prisoner. They even knew where the Lassie was anchored. For the moment he was at his wit’s end, unable to decide whether to go back and warn Terry to sail away, or stay and try to save Don. He was trying to figure out just what their object was when Frank unconsciously helped him.

“You figure it’ll be worth while to take in all three of them?” he asked.

Benito nodded. “I don’t know a thing about that third fellow,” he admitted. “But I do know that Mr. Mercer will pay plenty to get his boys back home. Meanwhile we’ll grab the sloop, give it a new coat of paint, and realize a pretty little penny from it. By the time the new owner finds out how we got it, we’ll be out of the country and safe.”

Jim’s eyes flashed fire, he clenched his teeth, and for a moment he had the impulse to smash his way through the window and hurl himself upon the two men. Realizing how rash and foolish such a move would be he controlled himself and waited, still uncertain as to what to do. He was tormented by the thought that he must decide wisely, for the wrong move might ruin everything. He wondered if Don was safe, and he was overjoyed to hear Frank’s next remark.

“We’ve got the older Mercer boy safe enough. Like enough he’ll soon get hungry and write that note to his father.”

“Oh, of course. It’s merely a matter of time. I judge that the boy is used to eating regularly and plenty, and I don’t think he’ll hold out long.”

“How are we going to get the other two?” Frank asked.

Benito looked at his watch. “Just as soon as Marcy gets back we’ll take the power boat and go out after them. We’ll muffle the oars and sneak up on ’em. I suppose they’ll be awake but it won’t take us long to overcome them. We’ll tow their sloop up the creek and take good care of it.”

Jim was beginning to wonder uneasily where Marcy might be, but Frank’s next remark reassured him. “Marcy’s taking a look in on young Mercer, ain’t he?”
