Jackson Brodie has relocated to a quiet seaside village in North Yorkshire, in the occasional company of his recalcitrant teenage son Nathan and ageing Labrador Dido, both at the discretion of his former partner Julia. It’s a picturesque setting, but there’s something darker lurking behind the scenes. Jackson’s current job, gathering proof of an unfaithful husband for his suspicious wife, seems straightforward, but a chance encounter with a desperate man on a crumbling cliff leads him into a sinister network - and back into the path of someone from his past. 

In rural Devon, six-year-old Joanna Mason witnesses an appalling crime. Thirty years later the man convicted of the crime is released from prison. In Edinburgh, sixteen-year-old Reggie works as a nanny for a G.P. But Dr Hunter has gone missing and Reggie seems to be the only person who is worried. Across town, Detective Chief Inspector Louise Monroe is also looking for a missing person, unaware that hurtling towards her is an old friend, Jackson Brodie, himself on a journey that becomes fatally interrupted.

It is the Edinburgh Festival. People queuing for a lunchtime show witness a road-rage incident--an incident which changes the lives of everyone involved. Jackson Brodie, ex-army, ex-police, ex-private detective, is also an innocent bystander--until he becomes a suspect. With Case Histories, Kate Atkinson showed how brilliantly she could explore the crime genre and make it her own. In One Good Turn, she takes her masterful plotting one step further.

Cambridge is sweltering, during an unusually hot summer. To Jackson Brodie, former police inspector turned private investigator, the world consists of one accounting sheet--"lost" on the left, "found" on the right--and the two never seem to balance. Jackson has never felt at home in Cambridge and has a failed marriage to prove it.
