He turned to the wall of the boathouse again.
“I tell you, he wouldn’t pay us for bringing him out to Cabin Island so often unless there was something behind it,” Ike Nash was saying.
“That’s all right. What if there is something behind it?” returned Carson. “It’s none of our affair. He pays us. That’s all we want. If Hanleigh cares to spend his time prowling around this island, why should we worry, as long as we get our money?”
The Hardy boys and their chums glanced at one another in surprise.
Hanleigh!
The man who had ordered them away from Cabin Island on their previous visit! The man whom Elroy Jefferson had said wanted to buy the place!
“I don’t see why he won’t let us go up to the cabin with him,” grumbled Nash. “What does he want to keep secret from us?”
“That’s his business,” snapped Tad Carson. “If you go asking questions, then you’ll just spoil everything. Leave well enough alone.”
“Well, what are we going to do now? That’s what I want to know.”
