“You possess a secret that the whole world has been hunting for, and we propose that the world will go on hunting for it before you will ever be able to tell it. Share with us and, under reservations, you will be well cared for. Refuse and, as we have gone so far, we will find—and you too—the rest of the way very simple. You’re not at this moment likely to be able to help yourself. That little incident outside,” Riddles nudged me again, “meant nothing. You’re as much buried alive in this attic in the first city of the world, as if you occupied a tomb of the Pharaohs. We’re not as self-controlled as you seem to be. We may get restless. Then, sir”—we heard him step forward; I imagined him leaning close to his victim, for it was evident the man was in some way confined—“then, sir, up you go—you and your secret—in smoke.”

His smothered rage broke out then, and we heard him strike the man and curse him. There was the remonstrance of a cry—that was all. The next instant we would have forced our way through a stone wall had we been against it, but Captain B. raised his hand. His trained endurance amazed me. The voice resumed:

“Now what do you propose to do?”

“Yes, what?” from the first ruffian.

We held our breaths and listened with all our ears.

“Let me get up. Let me talk this over with you. You are driving me crazy! I can’t think. I will forget what you say I know. You—”

“Hell with your parleying. I’ll untie your tongue. I guess your memory will work quick enough after this”; it was Husky threatening.

Then succeeded the jeering encouragement of the woman and, strange paradox, the voice was rich, enticing, but mocking.

“Oh, yes; just a little stimulation will hurry up matters. Diaz we can’t wait much longer and,” the menad fury broke loose, “if this miserable creature holds out much longer we shall be ruined. Burn him—burn him—scald it out of him, Huerta; the dolt, simpleton, idiot—”

There was a shuffling movement inside, the sudden bristling, rushing sound of an airblast (Could it be a naphtha lamp?) and then a raving, rending, terrifying cry, something that meant fear and rage and madness, the awful, marrow-chilling shriek of insanity.
