Richard Diamond, Private Detective - The Van Dyke Seance Case

Richard is visited by Miss Nancy Van Dyke at his office. She says "I'm worried about my aunt, Mr. Diamond. Lately she's been seeing a man who calls himself Dr. Langley". Richard asks "Are you of the Long Island Van Dykes?" She says "Well, we used to live on Long Island, and yes, we are quite wealthy". Richard asks "You think this Dr. Langley is after your aunt's money, is that it?" She says "Yes. He's been taking her to see a clairvoyant, and she claims that he produced her dead mother and that she talked with her. My aunt says that this apparition, or whatever it is, warned her of impending danger". Richard asks "What's the medium's name?" Nancy says "He calls himself Professor Leonardo". Richard says "What else did the ghost have to say?" Nancy says "Well, she said, or it said, to trust Dr. Langley, and that's exactly what my aunt started to do. She even consults him on matters of business. He's completely sold her on this phony Professor Leonardo, and unless I miss my guess, he's got a wandering eye for her jewelry collection. She had it out, and she was showing it to him last evening". Richard asks "What do you want me to do?" Nancy says "I want you to prove that this Dr. Langley and the Professor are charlatans. If you can do that, please report it to my aunt. Then, stop by my place at 741 Madison Avenue, and I'll pay you the rest of your fee".
