“You see it didn’t kill us,” pursued Don.
“Born to be hung, perhaps,” conjectured Teddy.
“And then too they wouldn’t have left that passage open to the tomb,” continued Don. “They’d have walled that hole all the way around. But they didn’t. They left it open for their own purposes.”
“Well, suppose they did, what does all this lead to?”
“Just this,” replied Don. “That those who came in that way didn’t expect to go back that way. No one could climb up that toboggan. It’s too steep and it’s too slippery, and there’s absolutely nothing to hold on to. You might as well try to climb up a looking glass.
“Now if they didn’t expect to go back that way, they must have meant to get out some other way. Get me?”
“Oh!” exclaimed Teddy, as a light broke in on him. “You mean there’s some other entrance to this place?”
“Yes,” replied Don. “Though in our case, as it was in theirs, it will be an exit. There must be some such place, and it’s up to us to find it.”
The boys drew new hope from the conclusion and set out at once to look for their one hope of safety. They tried to find the source from which the light filtered in, thinking, naturally, that this would be the key to the enigma.
But search as they would, the secret evaded them. The marvelously cunning architects and engineers of ancient times had done their work well, if their intention was to confuse and bewilder any unwarranted visitor.
