When police officers arrive at Scott and Blair Bagby’s home asking whether their teenage son is there, they know something is terribly wrong.

Jamie’s body has been discovered in a shallow grave in Peasedale Woods. He is not alone. Buried around him are the remains of boys murdered by a serial killer who has been hiding inside their quiet English community.

But Jamie’s death does not fit the killer’s pattern.

A desperate final phone call. An abandoned hunting shack. Evidence the police cannot explain. Each discovery points toward a possibility more devastating than murder: Jamie may not have been one of the killer’s chosen victims.

He may have been the boy who helped lure them.

As suspicion turns grieving families and neighbours against them, Scott and Blair begin searching for answers of their own. Their marriage starts to fracture. Blair begins seeing Jamie. And every secret they uncover forces them to question how well they ever knew their child.

Was Jamie an innocent boy caught in a monster’s path—or part of the reason other boys never came home?

The Other Boy is a dark British psychological thriller about grief, guilt, family secrets, and the terrifying possibility that the child you loved was someone else entirely.
