Nick observed that there was a low couch, with a roll of skins, at one side of the cavern, and that a pitcher and some coarse cakes lay beside it on the floor.

He clapped his hand to his mouth to stifle a cry.

What Patsy had seen in the strange creature’s skinny fingers was the head of a man—a man with a light-colored beard, hair, and eyebrows. The head had been reduced to the size of an orange.

The head was not artificial. A single glance was enough to assure him of that. No, it was a real head, but in miniature.
