Blood has always been thicker than water for two Northern Irish brothers caught in the Belfast foster system, but a debt of past violence will be paid not just by them but also by those they left behind. Ciaran Devine, who made Belfast headlines seven years ago as the "schoolboy killer", is about to walk free. At the age of 12, he confessed to the brutal murder of his foster father; his testimony mitigated the sentence of his older brother, Thomas, who was also found at the crime scene, covered in blood.

Young Michael, an illegal immigrant escaping the troubles in Northern Ireland is strong and fearless and clever, just the fellow to be tapped by Darkey, a crime boss, to join a gang of Irish thugs struggling against the rising Dominican powers in Harlem and the Bronx. The time is pre-Giuliani New York, when crack rules the city, squatters live furtively in ruined buildings, and hundreds are murdered each month.

Northern Ireland, spring 1981. Hunger strikes, riots, power cuts, a homophobic serial killer with a penchant for opera, and a young woman’s suicide that may yet turn out to be murder: on the surface, the events are unconnected, but then things—and people—aren’t always what they seem. Detective Sergeant Duffy is the man tasked with trying to get to the bottom of it all. It’s no easy job—especially when it turns out that one of the victims was involved in the IRA but was last seen discussing business with someone from the loyalist Ulster Volunteer Force.

All Bunny McGarry wants is a spot of breakfast and a decent cup of tea. So imagine how annoyed he gets when two masked men attempt to rob the New York diner he is in. Unfortunately, dealing with that problem just leads to a whole lot more. One of the diner’s other customers isn’t who she appears to be, and the odds aren’t great that she is going to live to see another breakfast.

The first time somebody tried to kill him was an accident. The second time was deliberate. Now Paul Mulchrone finds himself on the run with nobody to turn to except a nurse who has read one-too-many crime novels and a renegade copper with a penchant for violence. Together they must solve one of the most notorious crimes in Irish history. Or else they’ll be history.
