Pathologist Toni Day knows her mother like the back of her hand. When her mother calls and asks her to investigate the disappearance of her best friend's husband, Dick, she knows better than to argue. Soon, Toni and her husband, Hal, are on their way back to her hometown of Long Beach, California, where another mystery awaits. Dick's wife, Doris, is convinced that the historic house she shares with Dick is haunted. To make things even more complicated, Doris is also suffering from a mysterious illness. When Toni and Hal arrive, Doris takes a sudden turn for the worse and ends up in a coma. While doctors struggle to diagnose and treat, Toni explores the historic house looking for clues. After she unearths evidence suggesting that Dick may not be who he seems, as well as a malfunctioning dumbwaiter, a laird's lug, a secret staircase, and a half-empty bottle of white arsenic, she also finds Dick's body. As a whirlwind investigation ensues that exposes a decades-old scheme and serial murders, Toni herself nearly becomes the final victim. A Deadly Homecoming is the gripping tale of a pathologist's journey back to her hometown to solve a complex murder case that leaves her own life precariously hanging in the balance.
