Bloomsday Dead is the 3rd book in McKinty‘s Michael Forsythe Trilogy.
Though he’s one of my favourite writers, the Michael Forsythe series is too violent for me. I was surprised I got through this one.
… living in Lima, reasonably well-hidden by the FBI’s Witness Protection Program, but Bridget Callaghan, whose fiancé he murdered twelve years ago, has an enduring wish to see him dead.
So when her two assassins pass him the phone to speak to her before they kill him, Michael thinks she just wants to relish the moment. In fact, out of desperation, she is giving him a chance to redeem himself.
All he has to do is return to Ireland and find her missing daughter.
