I know you know : a novel
(Book)

"Twenty years ago, Charlie Paige and Scott Ashby were murdered in the city of Bristol, their bodies dumped near a dog racing track. A man was convicted of the brutal crime, but decades later questions still linger. Filmmaker Cody Swift has been haunted by the deaths of his childhood best friends; the loose ends of the police investigation consume him and he returns to Bristol in search of answers. Cody starts a podcast to record his findings, but there are people who don't want the case, along with old wounds, reopened so many years after the tragedy. Charlie's mother, Jess, decides to take matters into her own hands. When a long-dead body is found in the same location the boys were left decades before, Detective John Fletcher, the investigator on the original case, must reopen his dusty files. -- adapted from jacket"
