Yesterday's Sins: The Road to Redemption Series by James Green
Charlie Bronski, US Air Force security expert turned successful cookery writer, now lives the quiet life with his wife beside the sea in Denmark. So why would anyone plant a bomb under his car?
Recognising it as a professional job, Charlie asks for help from the people who set him up in his new life. They want a favour in return: for him to kill a middle-aged man, a trainee priest who caused them some problems - surely an easy task for someone with Charlie's military training.
But that man is ex-copper, ex-criminal, Jimmy Costello, a man with powerful friends - and powerful enemies. Will Charlie's past catch up with him before he catches up with Jimmy - and will Jimmy make it through alive?
The third in James Green's critically acclaimed series featuring his hardboiled former London detective.
