“Hello, Johnny. How about those pictures we took yesterday?” It was Dave who spoke.

“Oh, yes,” Johnny exclaimed. He had forgotten them. “Come on to the darkroom, if you like. I’ll develop them right away.”

Doris accompanied them to the darkroom. There, fascinated, they watched strange creatures of the depths come out on the film.

The great, shadowy creature which had peered out from a rocky cavern was, the picture revealed, a veritable deep-sea monster.

“If only I could bring him up!” Dave exclaimed. “But then, he’d never live at surface levels. But our great, sea-green octopus, I do believe, could live anywhere. I’m going after him!”

Most interesting of all—and most baffling—was the picture Johnny had taken of the great, slow-moving thing seen in the open water far from the rocks.

“Oh, that!” exclaimed Dave, as it began coming out in the film, “that’s really a monster for you!”

“If it is a monster,” said Johnny, in a tone of mystery.

Whatever it might be, the picture only added to the mystery. Too far away, too indistinct to be seen clearly, the thing might have been a whale, or some other form of deep-sea monster. Truth was—deep down in his heart Johnny believed it to be neither. His theories were too fantastic to be put into words—at the moment.
