“A criminal-ghost or a ghost-criminal?” asked Marie with a laugh.

“Either or both.”

“And you want us to spend a night there? Ugh! Excuse me—never!” declared Alice.

“I don’t mean stay there all night,” explained Natalie. “We could get the other camping boys—the ones who took us over to the Point last night—to run us to the mill in their launch. Then they could go off and leave us—or stay within call, maybe, and we could search all over the place for the secret room. I’m almost sure we can find it—I’m always lucky that way.”

“I wish you’d find mother’s diamond ring then,” said Mabel with a sigh.

“Will you come, girls?” persisted Natalie.

“We’ll come home before dark; won’t we?” asked Alice.

“If you like; but it’s going to be a lovely moonlight night, and it will be grand on the water.”

“Why not ask our own boys to take us over?” suggested Mrs. Bonnell.

“They wouldn’t,” said Mabel. “I think Nat’s plan is good—but I won’t stay in that spooky place after dark.”
