"And you've known about this place all the time?"
"I've suspected it, but I only found the way in to-night. Look here, I think we'd better reserve my story till we're out of this, don't you? Miss Fortescue must be worn out. How did you get here?"
"Through the panel in the library!" Margaret said. "I found it by accident."
"Then there is an entrance from the Priory!" Michael exclaimed. "But you didn't come down here just for fun, did you?"
"No, no!" Margaret said, and quickly told him all that had happened to them.
He listened frowningly. His comment, which made Margaret laugh, was: "Damn. From my point of view this is the worst thing that could possibly have happened."
He saw her eyes dancing, and smiled ruefully. "Yes, I know, but don't you see that when the Monk finds you're gone to-morrow night he'll know this place is discovered, and clear out. And the devil's in it that I don't know where his get-away is." He shrugged. "Well, I shall have to find it during the next twelve hours, that's all. The first thing to do is to get you out of here."
"By the way, where are we?" Peter asked.
"You're under the Priory."
"I thought as much! But did you get in by the panel in the library?"
