From the author who brought you the jaw-dropping twist of I Let You Go, the gasp-out-loud ending of Let Me Lie, and the loveable, unpredictable Ffion Morgan in The Last Party and A Game of Lies. Pre-order now to be first to read Clare Mackintosh's new thriller.

When the body of an estate agent is found in an upturned kayak on Mirror Lake, DC Ffion Morgan quickly realises the accident has been staged. There's no love lost between Ffion and estate agents, but who hated this one enough to want her dead?

Over the border in Cheshire, DS Leo Brady has his own property nightmare on his hands. The Hill is the kind of place where owners relish people gawking at their multi-million-pound homes - but now someone is breaking and entering their houses one by one.

Ffion and Leo are about to learn that people will pay a high price to keep their secrets behind closed doors. And even on the most desirable street, there's a dark side . . .
