"What can it mean?" India asked.
"I don't know, unless——"
"Unless what?"
"Can it be a direction for finding something?"
"But what? And why should it be hidden in his hat? Besides, he would have no chance to put it in there after he was captured."
"Then perhaps it isn't a message to me at all."
"That's what we must find out. 'At wharf above camp.' That probably means his fishing camp."
"What are you going to do, India?"
"I'm going to get Ned to help me find that gunny sack."
