Big sky

"Jackson Brodie has relocated to a quiet seaside village in the occasional company of his recalcitrant teenage son and an aging Labrador both at the discretion of his ex-partner Julia. It's picturesque but there's something darker lurking behind the scenes. Jackson's current job gathering proof of an unfaithful husband for his suspicious wife is fairly standard-issue but a chance encounter with a desperate man on a crumbling cliff leads him into a sinister network - and back across the path of his old friend Reggie."--Jacket flap.
