It Might Not Be Murder, but. This novel brings together a Chief of Detectives in New Scotland Yard and an academic from the halls of a prestigious University in the States. Their respect for one another and their successes in solving crimes in the Metro London area foster a close and respectful relationship. Chief Inspector Ian MacPherson hires Dr. David Campbell, a retired Professor, as a temporary Sergeant. Dr. Campbell has offered to work as a low paid Sergeant in order to learn to inner workings of Scotland Yard and to enhance his background and experience. Dr. Campbell plans to write about his work as a consultant in the LAPD and his experience in Scotland Yard as a part of his retirement. Dr. Campbell's introduction to the London Metro Force is unusual. He is "arrested" for attempting to enter England without a valid passport. His passport suddenly became filled with blank pages, between the time he last checked it, upon landing, and arriving at the customs inspectors. His training started early, explained Chief Inspector MacPherson, when he is taken to Scotland Yard. Dr. Campbell realized it had been a long time since he had last experienced a "Hazing." The novel follows Campbell through his indoctrination and then the Dixson case, where the demise of Mrs. Dixson is complicated by the fact that the cause of death is listed as "Unknown" by the Medical Examiner. There is no suspect. Death occurred in her own living quarters, there is no evidence of forced entry, no poisons were detected and there is evidence that her death was not by natural causes: To the Hawkins Manufacturing Company, where the VP of Manufacturing is found crushed to death in the bed of a large hydraulic press: To Brighton, England where MacPherson recognizes a man that participated in a terrorist bombing that killed his wife, while they were visiting Paris five years previously: To the case of Helen Blakely whose body is found in her car at the bottom of a deep ravine. There are no skid marks. Campbell proves that the prime suspect could not have been involved in her death. The newly formed "MacPherson Team" is put together and develops a psychological profile of the perpetrator and ties together bits and pieces of information to find the killer: To the end of the Dixson case when a friend of Mrs. Dixson comes to Scotland Yard to find out the cause of death and who was responsible. Mrs. Brooks tells MacPherson she brought a gift to Mrs. Dixson in order to thank her for her help in the past, and for her friendship. Thus, Mrs. Brooks was in Mrs. Dixson's living quarters on the day of her death. An innocent comment leads to closure of the Dixson case. The book presents a methodology in criminology that has a greater emphasis on the "Psychological" aspects of the total equation.
