Mick Herron: Dolphin Junction

When a wife leaves her husband under suspicious circumstances, he sets off in search for her, unprepared for the guilty secrets he's about to drag back into the light. A man is tempted by a luxury apartment with a top-of-the-range kitchen. But there is a heavy price to pay for this glamorous new life. A couple go on a hike through the Derbyshire countryside, to ignore the fact their marriage is on the rocks. And there is a peek into the past of Jackson Lamb, the boss of Slough House, as well as stories featuring the shrewd detective Zoe Boehm and her hapless partner Joe Silvermann. Dolphin Junction displays Herron's craft for deftly plotted storytelling, dark wit, and memorable twists.
