“That’s right! I can’t describe it to you! But I can show you. Question is—can you take pictures in complete darkness?”

“They don’t come too dark for me!” Johnny flashed back. “Lee Martin and I took a picture of a Voodoo witches’ meeting—people hiding in the dark from the island police. You couldn’t see your hand. But we got the picture all right. And I nearly lost an ear! A burly black fellow swung at me with a machete!”

“Nothing like that down there,” Dave chuckled. “All the same—you’ll be surprised! Do you want to go?”

“Sure—I’ll go,” Johnny agreed. “Only,” he hesitated, “I have a strange horror of being completely out of touch with the rest of the world! What do we do about that?”

“That’s easy!” Dave laughed. “We have a short-wave set on the boat and another in the steel ball. Doris or the professor is always listening in. How about it—do we go?”

“We sure do!” Johnny grinned.

“O.K.! Get your stuff together. We’ll go down in an hour!”

“Wonder what I’m getting into now?” Johnny asked himself as he walked to his stateroom.

An hour later he found himself passing through one of the strangest experiences of his life. He was seated, doubled up. Had he wanted to stand, he could not have done so. His eyes were wide open, but he saw never a thing!

“Inky black!” he whispered.
