In 'Ill Will', Dustin Tillman's life unfurls into a taut psychological thriller when his adopted brother, Rusty, is released from prison after DNA evidence overturns a decades-old conviction for the murder of Dustin's family. Haunted by the memory of the crime, which was mired in Satanic cult hysteria, Dustin's life takes a darker turn as he becomes entangled in the mystery of a series of drownings involving college boys. Initially skeptical of a serial killer, Dustin's own investigation pushes him to the precipice of obsession, blurring professional lines and jeopardizing his family's safety. Dan Chaon masterfully weaves a narrative that probes the murky depths of memory and self-deception, where the past and present are both shadowed places, and the truth is as elusive as it is dangerous.
