We Know What You Did Last Summer

A summer scare rooted in urban legend and real-life horror. From the hook-handed tale that haunted teenage lovers, to the Texarkana Moonlight Murders, to the film I Know What You Did Last Summer—and the chilling true story of author Lois Duncan’s murdered daughter. What begins as a cautionary campfire story spirals into a web of true crime, pop culture, and devastating personal loss. The truth behind the fiction is darker than you think.
