Hide and seek. And kill.
An old couple knelt side by side in an otherwise empty small town church, their heads resting on their hands in a picture of devotion. Both had small, tidy bullet holes in the backs of their skulls.
To local police their slaying looks like a one-off act of retribution.
At the same time, in Minneapolis, teams of detectives are scrambling to stop a sickeningly inventive serial killer striking again in a city paralysed by fear.
No one makes a connection.
But when the two separate investigations converge on an isolated Catholic boarding school, decades-old secrets begin to fall away. It seems an old killer has resurfaced. But one whose identity still remains dangerously out of reach.
Crackling dialogue, pace and rich, vivid characters all distinguish this electrifying debut thriller. Make sure you've locked your door . . .
