“O, yes,” said the voice. “There is enough power, Mrs. Ogilvy, but we are anxious to conserve it all for the materialisations. Martin says they are building up very well.”

At this moment the curtain in front of the cabinet began to sway. It bellied out as if a strong wind were behind it. At the same time a breeze was felt by all who were in the circle, together with a sensation of cold.

“It is quite chilly,” whispered Enid, with a shiver.

“It is not a subjective feeling,” Mailey answered. “Mr. Harry Price has tested it with thermometric readings. So did Professor Crawford.”

“My God!” cried a startled voice. It belonged to the pompous dabbler in mysteries, who was suddenly faced with a real mystery. The curtains of the cabinet had parted and a human figure had stolen noiselessly out. There was the medium clearly outlined on one side. There was Mrs. Linden, who had sprung to her feet, on the other. And, between them, the little black, hesitating figure, which seemed to be terrified at its own position. Mrs. Linden soothed and encouraged it.

“Don’t be alarmed, dear. It is all quite right. No one will hurt you.”

“It is someone who has never been through before,” she explained to the company. “Naturally it seems very strange to her. Just as strange as if we broke into their world. That’s right, dear. You are gaining strength, I can see. Well done!”

The figure was moving forward. Everyone sat spell bound, with staring eyes. Miss Badley began to giggle hysterically. Weatherby lay back in his chair, gasping with horror. Neither Malone nor Enid felt any fear, but were consumed with curiosity. How marvellous to hear the humdrum flow of life in the street outside and to be face to face with such a sight as that.

Slowly the figure moved round. Now it was close to Enid and between her and the red light. Stooping, she could get the silhouette sharply outlined. It was that of a little, elderly woman, with sharp, clear-cut features.

“It’s Susan!” cried Mrs. Bolsover. “Oh, Susan, don’t you know me?”
