The Shadows by Alex North
You knew a teenager like Charlie Crabtree. A dark imagination, a sinister smile—always on the outside of the group. Some part of you suspected he might be capable of doing something awful. Twenty-five years ago, Crabtree did just that, committing a murder to shocking that it's attracted that strange kind of infamy that only exists on the darkest corners of the internet--and inspired more than one copycat.
Paul Adams remembers the case all too well: Crabtree--and his victim--were Paul's friends. Paul has slowly put his life back together. But now his mother, old and suffering from dementia, has taken a turn for the worse. Though every inch of him resists, it is time to come home.
It's not long before things start to go wrong. Paul learns that Detective Amanda Beck is investigating another copycat that has struck in the nearby town of Featherbank. His mother is distressed, insistent that there's something in the house. And someone is following him. Which reminds him of the most unsettling thing about that awful day twenty-five years ago.
It wasn't just the murder.
It was the fact that afterward, Charlie Crabtree was never seen again?
