A Stranger. A promise. A deadly game.

Danny and Sharon Evans are desperate for answers. Why did their seemingly happy daughter try to take her own life?

When a stranger approaches Danny, saying he knows who’s to blame, Danny is tempted, despite Sharon’s reservations. And when his new friend offers them revenge, how can he walk away?

But little does Danny know he is being invited to play a terrible game. A game that won't just change lives – it will end them.

DI Joel Norris knows this is no ordinary case when two seemingly unconnected murders hit his desk within a matter of days. But how far is he willing to go to solve the puzzle?

Dark, gripping and unforgettable, The Friend will keep fans of Harlan Coben and Matt Brolly on the edge of their seats.
