It had no publication date, but John George Hohman, the author, dated his preface from Berks County, Pennsylvania, on July 31, 1819. In the secondary preface filled with testimonials as to the success of Hohman's miraculous cures, was included the pious ejaculation: "The Lord bless the beginning and the end of this little work, and be with us, that we may not misuse it, and thus commit a heavy sin!"

"Amen to that!" said Lanark to himself, quite soberly. Despite his assured remarks to Jager, he was somewhat repelled and nervous because of the things Enid Mandifer had told him.

Was there, then, potentiality for such supernatural evil in this enlightened Nineteenth Century, even in the pages of the book he held? He read further, and came upon a charm to be recited against violence and danger, perhaps the very one Jager had offered to copy for him. It began rather sonorously: "The peace of our Lord Jesus Christ be with me. Oh shot, stand still! In the name of the mighty prophets Agtion and Elias, and do not kill me...."

Lanark remembered the name of Elias from his boyhood Sunday schooling, but Agtion's identity, as a prophet or otherwise, escaped him. He resolved to ask Jager; and, as though the thought had acted as a summons, Jager came almost running into the room.

"Lieutenant, sir! Lieutenant!" he said hoarsely.

"Yes, Sergeant Jager?" Lanark rose, stared questioningly, and held out the book. Jager took it automatically, and as automatically stowed it inside his shirt.

"I can prove, sir, that there's a real devil here," he mouthed unsteadily.

"What?" demanded Lanark. "Do you realize what you're saying, man? Explain yourself."

"Come, sir," Jager almost pleaded, and led the way into the kitchen. "It's down in the cellar."

From a little heap on a table he picked up a candle, and then opened a door full of darkness.
