“Let Miss Enid Challenger come. We work together, you know.”

“Why, of course I will. Will you let her know?”

“Certainly.”

“It’s at seven o’clock to-night. The Psychic College. You know the place down at Holland Park.”

“Yes, I have the address. Very well, Miss Challenger and I will certainly be there.”

Behold the pair, then, upon a fresh psychic adventure. They picked Atkinson up at Wimpole Street, and then traversed that long, roaring, rushing driving belt of the great city which extends through Oxford Street and Bayswater to Notting Hill and the stately Victorian houses of Holland Park. It was at one of these that the taxi drew up, a large, imposing building, standing back a little from the road. A smart maid admitted them, and the subdued light of the tinted hall-lamp fell upon shining linoleum and polished wood-work with the gleam of white marble statuary in the corner. Enid’s female perceptions told her of a well-run, well-appointed establishment, with a capable direction at the head. This direction took the shape of a kindly Scottish lady who met them in the hall and greeted Mr. Atkinson as an old friend. She was, in turn, introduced to the journalists as Mrs. Ogilvy. Malone had already heard how her husband and she had founded and run this remarkable institute, which is the centre of psychic experiment in London, at a very great cost, both in labour and in money, to themselves.

“Linden and his wife have gone up,” said Mrs. Ogilvy. “He seems to think that the conditions are favourable. The rest are in the drawing-room. Won’t you join them for a few minutes?”

Quite a number of people had gathered for the séance, some of them old psychic students who were mildly interested; others, beginners who looked about them with rather startled eyes, wondering what was going to happen next. A tall man was standing near the door who turned and disclosed the tawny beard and open face of Algernon Mailey. He shook hands with the newcomers.

“Another experience, Mr. Malone? Well, I thought you gave a very fair account of the last. You are still a neophyte, but you are well within the gates of the temple. Are you alarmed, Miss Challenger?”

“I don’t think I could be while you were around,” she answered.
