John Wayne Gacy, known as the “Killer Clown,” drew public attention with his entertaining performances, but in secret—away from everyone—he killed people. Disguised as a caring husband and stepfather, he created a kingdom of terror in Chicago, watching young boys from the ghettos and killing them brutally. His crimes were uncovered thanks to police surveillance and led to one of the most shocking trials in the history of the United States. This book is based on the memories of police officers, lawyers, and prosecutors and tells the full story of this notorious killer.
