"We want to know if we could leave our motorcycles here for safe-keeping?" asked Frank.

"Certainly. Most certainly, you can. There's a shed back of the house, where you can put 'em. Is it just for an hour or so? Goin' up on the cliffs?"

The fisherman's expression changed instantly.

"Explorin' the caves!" he exclaimed. "You'd best go back home. There's strange doin's in the caves these days. It's no place for boys."

"There's nothing to laugh at, young man," returned the fisherman tartly. "I've lived here for twenty years and I'm no fool. The caves ain't healthy just now."
