At the harbor, Pip found a row of crooked old boathouses. On the wall of the last one hung a faded paper that looked exactly like her map's missing half. But it sat behind a cracked glass case, locked shut with a rusty padlock.
Pip spotted a loose board beside the case and wiggled it free. Behind it hung a small key on a string. She fit it into the rusty padlock, and with a squeak the case swung open. She lifted out the missing map half and pressed the two torn edges together. They matched perfectly.
The joined map showed a dotted path to the old lighthouse on the point. Pip biked there with Biscuit running beside her. At the base, the final mark pointed to a loose stone. Behind it sat a box of polished sea glass, a brass compass, and a note: "For the one brave enough to follow." Pip had found the treasure.
