“What is happening to Leoncia?” Torres demanded slyly. “I saw her run back. May she not be in danger by herself?”

Letting Torres live and dragging the old man by the arm, Francis waded back to the chamber of the idols, followed by Torres. Here, at sight of him, Leoncia screamed her horror again.

“It’s only Torres,” Francis reassured her. “He gave me a devil of a fright myself when I first saw him. But he’s real flesh. He’ll bleed if a knife is stuck into him.—Come, old man! We don’t want to drown here like rats in a trap. This is not all of the Maya mysteries. Read the tale of the knots and get us out of this!”

“The way is not out but in,” the priest quavered.

“And we’re not particular so long as we get away. But how can we get in?”

“From the mouth of Chia to the ear of Hzatzl,” was the answer.

Francis was struck by a sudden grotesque and terrible thought.

“Torres,” he said, “there is a key or something inside that stone lady’s mouth there. You’re the nearest. Stick your hand in and get it.”

Leoncia gasped with horror as she divined Francis’ vengeance. Of this Torres took no notice, and gaily waded toward the goddess, saying: “Only too glad to be of service.”

And then Francis’ sense of fair play betrayed him.
