Kidnap Marilyn

Marilyn Monroe’s tragic story still intrigues those concerned with truth and justice. Many have speculated about her fate, often rejecting the coroner’s finding of suicide. Various theories proffered include accidental drug overdose and murder by the FBI, KGB, etc. It has even been claimed she was secretly sequestered in a distant mental institution.

The scenario described in this book is far more plausible and explores our government’s role in this epic mystery. This then is what could, and more importantly, should have happened.

John J. Nance, New York Times best-selling author says:

“A fast, exciting, and thought-provoking read. Dr. Alan Diehl has cleverly crafted the known elements of Marilyn Monroe’s reported demise with a second and third layer of probability that suggests a very different conclusion. This is a tightly woven tale of intrigue by a master of accident forensics, and one you will not want to put down, even at 3 AM.”
