"Mr. Lester," he said, leaning forward in his chair and speaking in a lowered voice and with great earnestness, "her father is mad—I am sure of it. No one but a madman would live and dress as he does; no one but a madman would devote his whole time to the study of the supernatural; no one but a madman would believe in the supernatural as he does."

But I shook my head.

"I'm afraid that won't do, Swain. A good many fairly sane people believe in the supernatural and devote themselves to its study—there is William James, for instance."

"But William James doesn't dress in flowing robes, and worship the sun, and live with a Hindu mystic."

"No," I smiled, "he doesn't do that," and I thought again of the mysterious light and of the two white-clad figures. "Does he live with a Hindu mystic?"

"Yes," said Swain, bitterly. "An adept, or whatever they call it. He's the fellow who kicked me out."

"Does he speak English?"

"Better than I do. He seems a finely-educated man."

"Is he a lunatic, too?"

Swain hesitated.
