“Hah!” said Griggs again, as Ned frowned and looked annoyed. “And you couldn’t find any way up there on to the top?”

“No,” said Chris rather sadly. “It would have been so easy then.”

“Yes, we could have worked it then, my lad. One would have been enough. I could have carried out a nice game there, and led ’em on.”

“And what about their arrows?” said Ned.

“Oh, I should have had to chance them. Kept out of reach, or dodged them. I could have led ’em right in so that they wouldn’t have heard the stones being lowered down, and got right away over the top and shut the door after me, while when they saw that they couldn’t follow, and went back, they’d have found themselves shut-in.”

“But—there’s—no way out over the top terrace,” said Ned mockingly.

“Well, I know there isn’t,” said Griggs coolly. “I’ve looked well myself three times over, because I was afraid that the enemy might find a way down some time, and take us by surprise.”

“It would have been so easy then,” sighed Chris; “but I don’t despair. We might find a way, after all, if we had a good search.”

“To be sure we might,” replied Griggs, “and I think I know where.”

“You do?” cried the boys together.
