The Library Murders

Alyssa Clark is about to find out that reading really can be murder.

She thought her new job in Thornhill Library would be safe and uneventful. Boring, even. But on her first day at work, a masked gunman storms into the building and blows away every member of staff on duty. Alyssa barely escapes with her life.

The police are satisfied they’ve got their man, but Davy, Alyssa’s colleague and the only other survivor of the massacre, is convinced the real killer is still at large. Alyssa – trying to move on with her life while dealing with traumatic flashbacks and the unwanted advances of an obsessive ex – is sceptical. However, when she stumbles across damning evidence of a cover-up, she agrees to join forces with Davy to help track down the real culprit.

But in her pursuit of the truth, will she find the closure she desperately craves… or provoke the wrath of a killer with unfinished business on his mind?

If you like twists, turns and compelling, conflicted characters, you’ll love this gripping new mystery from the McIlvanney Prize-nominated author of In the Silence.
