At 9:00 on the morning of March 6, 1963, in the quiet St. Paul neighborhood of Highland Park, Mrs. Fritz Pearson glanced out her window and saw something almost unimaginable: slumped on the front steps of the home across the street was a woman, partially clothed in a blue bathrobe and bloodied beyond recognition. The woman, Mrs. Pearson would come to learn, was her beloved neighbor Carol Thompson, wife and mother of four. Earlier that morning, T. Eugene Thompson, known to friends as "Cotton," dropped his son off at school and headed to the office, where he worked as a criminal attorney. At 8:25 am, he phoned home, later telling police that he did so to confirm evening plans with Carol. Mr. Thompson lied. Through police records, court transcripts, family papers, and extensive interviews, William Swanson has re-created Middle America's "crime of the century," the deadly plot by a husband that made headlines around the world. But Dial M: The Murder of Carol Thompson also tracks the lives of the Thompsons' children. Their journey from disbelief to acceptance culminates in a private family trial where they decide whether their father truly was responsible for the violent act that crushed their childhood and forever altered their views of the world.
