For some moments the bishop cracked his knuckles in silence; his cavitous eyes fixed keenly on the old, withered man before him, who still looked dumbly at the pearl on the table.

“Yes; they are best caged,” resumed the bishop in soft, meditative tones. “And yet those closely confined are most dangerous when given a little liberty. The breath of freedom—that insane folly—soon heats the blood and leads them to wild excesses. Had I not felt so sure of the priest’s virtue, I would not have permitted him to teach her and lay himself open to temptation. I did not think he would submit. But no risk is so great as to be lenient or careless with the caged. Open the bars and animals will go forth. Play with their claws and they will scratch. Tantalise their hungers and uncaged they will gorge. The wisest way is to teach them a few tricks—a very few, and when not performing keep them behind bars. Man’s greatest self-deception is to believe that they are tamed. No animal has ever yet been so gentled that it could be left to its own instincts. Nothing is more dangerous. How many keepers have been lacerated to death by this one act of careless confidence!

“But I do not know how she could have managed it,” the bishop’s tones became filled with deep concern. “Surely she was not so bold and immodest as to come from behind the screen?”

Tai Lin raised his eyes from the ring and looked startled, mutely about him.

The bishop wiped his lips, and behind the handkerchief a smile flickered.

“Yet there are worse things than her coming from behind the screen,” he continued compassionately. “If it had only stopped there, for the pride of beauty may have moved her unconsciously; impelled by nature she may have crept unseen to his side.

“This manner of movement is peculiar to women and—snakes.

“Did Your Excellency know that during the first month of the world’s birth these two met—a snake and a woman? Being unable to swallow each other, they made perpetual compact—to devour man.

“Since then they have possessed many attributes in common. Their tongues have the same forked rapidity; poison lurks in their kisses; death in their embraces. One-half of them is allurement, the other half desire. In gorgeous bedeckment they resemble flowers—men often mistake them for such. Their backs are beautiful with radiant colours, their bellies pallid. One coaxes what the other devours. Nothing can equal the subtlety of their movement! One never feels them until bitten; one never knows them until the heart has been clogged by their poison. Thinking them an innocent flower on account of their hues and beauty, one reaches out after them and finds—what Your Excellency has discovered.”

A shudder passed through the old man.
