It's the year 2000 in Dublin and, following some traumatic events, Detective Bunny McGarry is taking a well-earned break from the force. However, just because you're not looking for trouble doesn't mean trouble isn't looking for you.

Bunny's former partner died in the line of duty under dubious circumstances but his murky background has suddenly resurfaced, threatening Bunny's reputation as well. As if that isn't enough, a young boy is in danger and a woman from the big fella's past is trapped in a loveless marriage to a monster. They both need Bunny's help, but he must get to work fast - it seems someone is trying to frame him for murder ...

Dead Man's Sins is a continuation of Caimh McDonnell's critically acclaimed bestselling Dublin Trilogy and mixes high-octane thrills with a distinctly Irish wit.
