The Man Who Killed Halloween — Ray Garton

Halloween, 1974: a gray and drizzly day in El Reno, Oklahoma, a suburb of
Oklahoma City. Todd Strauss is dressed up as a pirate with a black cloth
patch over one eye. His six-year-old sister Lisa is a princess with a tiara
made of Christmas garland and pipe cleaners. One of these kids will be dead
before the night is over, and the town will find itself gripped by a terror
they have never known before...
