Big Sky by Kate Atkinson

ObserverJackson 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. Old secrets and new lies intersect in this breath-taking new literary crime novel, both sharply funny and achingly sad, by one of the most dazzling and surprising writers at work today.
