There, on a small sign, he read:

Anita Marie Psychic Circle

Anita Marie was a spirit medium! Not only that, but she was using the same title that Professor Raoul Jacques had employed with his group of believers in New York.

Reaching the corner, Cardona drew a tabloid newspaper from his pocket. He had looked through the personal columns before, but he had not noticed anything of special interest, although he remembered that the word psychic had appeared there.

He discovered it again — in two or three announcements. One stated as follows: Psychic meeting to-night. Friendly visitors welcome. Eight o'clock.

Beneath the notice appeared the address of Anita Marie.

It was already late in the afternoon. Cardona decided to wait until eight o'clock. He found a restaurant in the vicinity and dined there. He was sure, now, that his mysterious tip-off had come from The Shadow. During his investigation of the Harvey murder, Cardona had realized that events in one seance room might have a possible connection with those in others. But the job of watching every medium in Manhattan and environs had seemed a ridiculous plan.

Cardona, in all his work, played for breaks that would lead him somewhere. He had found one now, and it was worth following.

Shortly before eight o'clock, he arrived at the home of Anita Marie. Cardona was astounded when he saw the rows of automobiles gathered on both sides of the street.

Evidently this medium did a rushing business at her Saturday-night seances. Cardona was impressed, in spite of himself.
