"We'll put you to the test a little, before Zorilla really begins—operating. Adjoining this apartment I see there is your most luxurious bathroom—the walls of onyx, the bath of solid silver. Well, we'll take you and put you in that bath and turn on the water. I'll stand over you, and with my hands on your shoulders, I'll plunge you an inch or two beneath the surface, till you are so nearly drowned that you taste all the bitterness of death.

"Yes. Give me one moment."

"Ten if you like."

Then there came in a calm, penetrating voice, "Are you there?"
