In the depths of his Cornish hideaway, retired Detective Inspector Frank Elder’s solitary life is disturbed by a call from his ex-wife, telling him his seventeen-year-old daughter, Katherine, is running wild, unbalanced by the abduction and rape he feels he should have prevented. Meanwhile, in the heart of London, the takedown of a violent criminal goes badly, and Detective Sergeant Maddy Birch is uneasy about the reasons why, an uneasiness that is compounded when she starts to believe she is being stalked.  Maddy and Frank had a brief and clumsy encounter years before. In Ash & Bone their lives connect again when a second phone call persuades Elder out of retirement, only to find that a cold case has a devastating present-day impact.
