Twenty years was almost long enough for Joe Kennedy to forget why he left Glasgow in the first place... now he's back to bury his best friend, Father Paul Connolly.
When Kennedy inherits a flash drive containing one of the Catholic church's darkest secrets, what begins as a final farewell turns into a lethal hunt through the city's rain soaked shadows.
With the Vatican Bank on his tail and a trail of laundered cash leading from the Highlands to the Holy See, Kennedy turns to Charlie, the lover he never quite left behind.
In a game where Rome pulls the strings and the Glasgow underworld provides the muscle, Kennedy quickly realises that trust is a luxury he can ill afford.
The drive is a death warrant, the truth a shocking conspiracy, and in Glasgow... nobody ever really leaves.
