Killer Unchained Case 3: The scariest true crime is the unsolved kind.

The scariest true crime is the unsolved kind. But some cases go beyond unsolved. Some cases go beyond anything a reader expects to find in a book.

Welcome to Cleveland, Ohio. 1935. The Great Depression has hollowed the city out, filling its ravines and rail yards with thousands of men and women who have nowhere else to go, people invisible to the city around them, people nobody will miss. Into that darkness walks something that experienced homicide detectives, hardened coroners, and one of America’s most celebrated law enforcement figures will spend years trying to understand and never quite manage to.

At least twelve victims. Possibly more. All decapitated with surgical precision. Several never identified. The crimes continued for years, defying every effort to stop them, and the man responsible was never caught, never charged, and never named with the certainty a court of law demands.

Join Simon King, author of the Prison Days series, as the Killer Unchained series takes its darkest turn yet. Ninety years of questions. Twelve bodies that still haven’t found justice. And a city that has never fully recovered from what walked through it in the 1930s.

The Mad Butcher of Kingsbury Run is waiting.
