“He’s a geologist,” said the sheriff. “Or anyway interested in geology. A sort of hobby with him. He tells me he looks for fossils.”

Adams assumed the alert look of a dog that has sighted a rabbit. “So that is it,” he said. “I bet you it ain’t fossils he is looking for.”

“No,” the sheriff said.

“He’s looking for minerals,” said Adams. “He’s prospecting, that’s what he’s doing. These hills crawl with minerals. All you have to do is know where to look.”

“You’ve spent a lot of time looking,” observed the sheriff. “I ain’t no geologist. A geologist would have a big advantage. He would know rocks and such.”

“He didn’t talk as if he were doing any prospecting. Just interested in the geology, is all. He found some fossil clams.”

“He might be looking for treasure caves,” said Adams. “He might have a map or something.”

“You know damn well,” the sheriff said, “there are no treasure caves.”

“There must be,” Adams insisted. “The French and Spanish were here in the early days. They were great ones for treasure, the French and Spanish. Always running after mines. Always hiding things in caves. There was that cave over across the river where they found a skeleton in Spanish armour and the skeleton of a bear beside him, with a rusty sword stuck into where the bear’s gizzard was.”

“That was just a story,” said the sheriff, disgusted. “Some damn fool started it and there was nothing to it. Some people from the university came out and tried to run it down. It developed that there wasn’t a word of truth in it.”

“But Daniels has been messing around with caves,” said Adams. “I’ve seen him. He spends a lot of time in that cave down on Cat Den Point. Got to climb a tree to get to it.”

“You been watching him?”

“Sure I been watching him. He’s up to something and I want to know what it is.”
