“Go with Ruth, you and Drake, and look at them. And bring them back with the pony. Then we'll make a start. A few minutes more probably won't make much difference—but hurry.”

He turned back to his watch. Ordering Chiu-Ming to stay with him I followed Ruth and Drake down the ruined stairway. At the bottom she came to me, laid little hands on my shoulders.

“Walter,” she breathed, “I'm frightened. I'm so frightened I'm afraid to tell even Mart. He doesn't like them, either, these little things you're going to see. He likes them so little that he's afraid to let me know how little he does like them.”

“But what are they? What's to fear about them?” asked Drake.

“See what you think!” She led us slowly, almost reluctantly toward the rear of the fortress. “They lay in a little heap at the mouth of the cleft where we heard the noises. Martin picked them up and dropped them in a sack before we ran through the hollow.

“They're grotesque and they're almost CUTE, and they make me feel as though they were the tiniest tippy-tip of the claw of some incredibly large cat just stealing around the corner, a terrible cat, a cat as big as a mountain,” she ended breathlessly.

We climbed through the crumbling masonry into a central, open court. Here a clear spring bubbled up in a ruined and choked stone basin; close to the ancient well was their pony, contentedly browsing in the thick grass that grew around it. From one of its hampers Ruth took a large cloth bag.

“To carry them,” she said, and trembled.

We passed through what had once been a great door into another chamber larger than that we had just left; and it was in better preservation, the ceiling unbroken, the light dim after the blazing sun of the court. Near its center she halted us.

Before me ran a two-feet-wide ragged crack, splitting the floor and dropping down into black depths. Beyond was an expanse of smooth flagging, almost clear of debris.
