Miss Jeremy, the medium, was due at 8:30 and at 8:20 my wife assisted Mrs. Dane into one of the straight chairs at the table, and Sperry, sent out by her, returned with a darkish bundle in his arms, and carrying a light bamboo rod.

“Don’t ask me what they are for,” he said to Herbert’s grin of amusement. “Every workman has his tools.”

Herbert examined the rod, but it was what it appeared to be, and nothing else.

Some one had started the phonograph in the library, and it was playing gloomily, “Shall we meet beyond the river?” At Sperry’s request we stopped talking and composed ourselves, and Herbert, I remember, took a tablet of some sort, to our intense annoyance, and crunched it in his teeth. Then Miss Jeremy came in.

She was not at all what we had expected. Twenty-six, I should say, and in a black dinner dress. She seemed like a perfectly normal young woman, even attractive in a fragile, delicate way. Not much personality, perhaps; the very word “medium” precludes that. A “sensitive,” I think she called herself. We were presented to her, and but for the stripped and bare room, it might have been any evening after any dinner, with bridge waiting.

When she shook hands with me she looked at me keenly. “What a strange day it has been!” she said. “I have been very nervous. I only hope I can do what you want this evening.”

“I am not at all sure what we do want, Miss Jeremy,” I replied.

She smiled a quick smile that was not without humor. Somehow I had never thought of a medium with a sense of humor. I liked her at once. We all liked her, and Sperry, Sperry the bachelor, the iconoclast, the antifeminist, was staring at her with curiously intent eyes.

Following her entrance Herbert had closed and bolted the drawing-room doors, and as an added precaution he now drew Mrs. Dane’s empty wheeled chair across them.

“Anything that comes in,” he boasted, “will come through the keyhole or down the chimney.”
