Gun Street Girl: A Detective Sean Duffy Novel (The Sean Duffy Series Book 4)

Belfast, 1985. Amid the Troubles, Detective Sean Duffy, a
Catholic cop in the Protestant Royal Ulster Constabulary, struggles with
burnout as he investigates a brutal double murder and suicide. Did Michael
Kelly really shoot his parents at point-blank and then jump off a nearby cliff?
A suicide note points to this conclusion, but Duffy suspects even more sinister
circumstances. He soon discovers that Kelly was present at a decadent Oxford
party where a cabinet minister’s daughter died of a heroin overdose, which may
or may not have something to do with Kelly’s subsequent death.

New evidence leads elsewhere: gun runners, arms dealers, the
British government, and a rogue American agent with a fake identity. Duffy
thinks he’s getting somewhere when agents from MI5 show up at his doorstep and
try to recruit him, thus taking him off the investigation.

Duffy is in it up to his neck, doggedly pursuing a case that
may finally prove his undoing.
