Shay Rynne grew up in the Corporation Flats — public housing — in Fenian Street, Dublin. He has always toyed with the idea of joining the Garda Síochána, the Irish police. But in the early 1970s, young fellows from the tenements of Dublin have not been welcomed in the police force. When his friend Rosaleen is killed and the case goes unsolved, Shay decides to put on the uniform of a Dublin garda and sets out to find the killer.
The murder inquiry makes an enemy of the detective who failed in the first investigation. Shay knows Detective McCreevy is just waiting for the chance to get revenge. But the violent death of a prominent politician gives Shay the opportunity to prove himself, perhaps even be promoted. Shay works with the lead detective on the murder inquiry and his star is rising, until suspicion falls on a member of Shay’s own family. So Shay is off the case. Officially. Determined to clear his family name, his under-the-radar investigation takes him from an opulent mansion in Dublin to Hell’s Kitchen in New York. And his good friend Father Brennan Burke has some surprising contacts for Shay in the shadowy world of New York’s Irish mob.
