Glasgow, 1969. In the grip of the worst winter for years, the city is brought to its knees by a killer whose name fills the streets with fear: The Quaker. He’s taken his next victim — the third woman from the same nightclub — and dumped her in the street like rubbish. The police are left chasing a ghost, with no new leads and no hope of catching their prey. After six months, DI Duncan McCormack, a talented young detective from the Highlands, is ordered to join the investigation — with a view to shutting it down for good.

His arrival is met with anger from a group of officers on the brink of despair. Soon he learns just how difficult life can be for an outsider, for McCormack is an outcast in more ways than one. When another woman is found murdered in a tenement flat, it’s clear the case is by no means over. From ruined backstreets to the dark heart of Glasgow, McCormack follows a trail of secrets that will change the city — and his life — forever . . .

Brilliantly crafted with great depth and nuance, The Quaker is an electrifying thriller that expertly captures the gritty atmosphere of paranoia and hopelessness in a city on the verge of a great upheaval.
