Landslide — David Menon

DSI Barton and his team investigate a particularly nasty crime when the body of a teenage girl is found in the boot of a car. She's had her legs cut off. She's been subjected to one of the most barbaric practices done to young girls. But who is she? How did she end up like that?
Meanwhile, one of Barton's oldest adversaries is back on the scene and making his presence felt. But why has he risked everything by coming back? He's a spent force. His former power over the gangland community of Manchester has gone. Someone else is sitting in his seat now.
When the sister of the murdered girl contacts Barton to say that she's in the same position as her dead sister, she's taking a massive risk with her own life. But she sets Baton and his team on a trail that exposes a serial killer to them. Tracking him down is one thing but have they got the right man? And what is his connection with the gangland warfare that plays out and places Barton's son Toby in mortal danger when he's abducted?
This one really does become as personal as it could possibly get.
