"Two detectives hunt a killer amidst the lawless streets and high society of 1930's Glasgow in this "brilliant" (Times UK) mystery that "serves up a delicious slice of thirties gangster noir" (Adrian McKinty)--inspired by the true story of the Scottish Untouchables. Glasgow, 1932. When the son-in-law of one of the city's wealthiest shipbuilders is found floating in the River Clyde with his throat cut, it falls to Inspector Jimmy Dreghorn to lead the murder case-despite sharing a troubled history with the victim's widow. From the flying fists and flashing blades of Glasgow's criminal underworld, to the backstabbing upper echelons of government and big business, Dreghorn and his partner 'Bonnie' Archie McDaid must dig deep into Glaswegian society to find out who wanted the man dead and why. All the while, a sadistic murderer stalks the post-war city, leaving a trail of dead bodies in their wake. As the detectives delve into the case, Dreghorn realizes that the answers may lie in his old ties with the victim's family--and the horrors he saw in the Great War"--
