They fell rather than sat down on the stone floor, their hands closely interlocked.

“Oh, Don, what was it?” quavered Teddy. “A ghost?”

“Ghost, nothing!” declared Don, trying to infuse stoutness into his denial. “You know as well as I do that there’s no such thing as a ghost.”

“I never did believe it till now,” said Teddy. “But what was that, if it wasn’t a ghost? Lots of people believe in them. Perhaps it’s the old king this tomb belongs to, and he’s come to warn us against coming here.”

“Nonsense!” replied Don.

“What was it then if it wasn’t a ghost?” challenged Don’s companion.

“How do I know?” countered Don, who by this time was getting back some of his usual self-possession. “It may have been some crazy person. Heaven knows, it’s enough to make any one crazy to be in here. It may have been a trick of some kind. Perhaps this is a robbers’ cave, and that’s a way they have to scare out intruders. I don’t know what it was, but I’m dead sure that it isn’t a ghost. And you know it isn’t, either.”

“I suppose it isn’t,” admitted Teddy, as common sense once more took the helm. “But it sure had me going for a minute.”

“Me, too,” confessed Don. “I never had such a scare thrown into me in my life.”

“If only it doesn’t come back!” sighed Teddy.
