The Guilty

In 2008, a four year old boy goes missing during a neighbourhood barbecue and his family's world falls apart. Five years later his body is found, and DCI Maggie Brand is faced with the most troubling case of her career.

As Maggie digs deeper into Callum Reid's disappearance, a trip to Germany places a key witness statement in a disturbing light. Claire makes a discovery with distressing implications.

Under pressure to charge her prime suspect, Maggie's still not convinced they've found the killer. Meanwhile, Theresa's return pushes Claire and Daniel's marriage to breaking point.
