From the bestselling author of AFTER THE CRASH ('a novel so extraordinary it reminded me of reading Stieg Larsson for the first time' Sunday Times): a man's wife goes missing. He didn't kill her so why is he so guilty?

Picture the scene - an idyllic resort on the island of Reunion. Martial and Liane Bellion are enjoying the perfect moment with their six-year-old daughter. Turquoise skies, clear water, palm trees, a warm breeze...

Then Liane Bellion disappears. She went up to her hotel room between 3 and 4pm and never came back. When the room is opened, it is empty, but there is blood everywhere. An employee of the hotel claims to have seen Martial in the corridor during that crucial hour.

Then Martial also disappears, along with his daughter. An all-out manhunt is declared across the island. But is Martial really his wife's killer? And if he isn't, why does he appear to be so guilty?
