"Doesn't that look like Mr. Mason from behind?" Henry grabbed the glasses. "I think it is him. I recognize the red hat he had on yesterday. If he had a motorboat, why did Hilda tell us they didn't have time to go to the hardware store?" Jessie found the towel she'd packed and shared it with Henry. "The sun will have to dry off the rest of us," she said. "If you ask me, those two are trying to keep us away from Cousin Charlotte's property." "Well, they can't," Henry said. "Hop in, everybody. We're going to follow Mr. Mason back to Skeleton Point." But Henry couldn't follow the motorboat to Skeleton Point. It sped right past there without stopping. "He must be docking someplace else," Jessie said. "That gives me an idea. Instead of going back to Skeleton Point, let's row to that cove we passed not too far from the general store. We'll hike up from there. If Hilda and William don't spot our boat coming in, we'll have a chance to see what they're up to before they expect us back." Henry didn't need to think twice about Jessie's good suggestion. He dipped one oar into the water and headed for the deserted cove. The Mystery at Skeleton Point"
