New York Times bestselling author Adrian McKinty continues the Edgar Award–winning Sean Duffy series with Hang On St. Christopher.

Rain slicked streets, riots, murder, chaos. It’s July 1992 and the Troubles in Northern Ireland are still grinding on after twenty-five apocalyptic years. Detective Inspector Sean Duffy got his family safely over the water to Scotland, to “Shortbread Land.” Duffy’s a part-timer now, only returning to Belfast six days a month to get his pension. It’s an easy gig, if he can keep his head down.

But then a murder case falls into his lap while his protégé is on holiday in Spain. A carjacking gone wrong and the death of a solitary, middle-aged painter. But something’s not right, and as Duffy probes he discovers the painter was an IRA assassin. So, the question becomes: Who hit the hit man and why?

This is Duffy’s most violent and dangerous case yet and the whole future of the burgeoning “peace process” may depend upon it. Based on true events, Duffy must unentangle parallel operations by the CIA, MI5, and Special Branch. Duffy attempts to bring a killer to justice while trying to keep himself and his team alive as everything unravels around them. They might not all make it out of this one.

A torso in a suitcase looks like an impossible case, but Sean Duffy isn’t easily deterred, especially when his floundering love life leaves him in need of a distraction. So with detective constables McCrabban and McBride, he goes to work identifying the victim.

The torso turns out to be all that’s left of an American tourist who once served in the U.S. military. What was he doing in Northern Ireland in the midst of the 1982 Troubles? The trail leads to the doorstep of a beautiful, flame-haired, twentysomething widow, whose husband died at the hands of an IRA assassination team just a few months before. Suddenly Duffy is caught between his romantic instincts, gross professional misconduct, and powerful men he should know better than to mess with. These include British intelligence, the FBI, and local paramilitary death squads - enough to keep even the savviest detective busy. Duffy’s growing senseof self-doubt isn’t helping. But as a legendarily stubborn man, he doesn’t let that stop him from pursuing the case to its explosive conclusion.
