Though Sean Duffy is as cool as they come (especially his eclectic musical taste) he isn't is as particular as James Bond about his alcohol: in fact he'll ingest most anything -- single malt scotch, pints of bitter, glasses of the black stuff, Vodka gimlets, enormous quantities of wine, cans of Bass . . . whatever, and he's not afraid to chase it with narcotics . . . stolen pharma grade cocaine, weed, codeine, or anything else that he runs across . . . sometimes this is to assuage physical pain, he often takes a beating, whether it's donning riot gear in Belfast, trying to keep some order as the lone Catholic in a Protestant housing project on Coronation Road in the town of Carrickfergus, discussing delicate matters with various Loyalist Protestant paramilitary groups in perpetual battle with the IRA, or getting officially roughed up by some American spooks for poking his nose where it doesn't belong . . . and sometimes he's drowning his troubles in drink and drugs to handle the mental anguish of being a "Fenian" peeler in the midst of the Troubles; in Adrian McKinty's new novel, Gun Street Girl, despite all this baggage the MI5 recognizes Duffy's talent and while his contact, Kate, remarks that "your house stinks of marijuana and Scotch, and there's what appears to be cocaine on the lapel of your dressing gown" she still wishes to enlist him in the British secret service, but then things get complicated . . . oddly, the wildest things in this novel are based on real events: a mysterious missile theft, MI5 agents lurking about Ireland in the 80's, a notable heroin overdose at Oxford, a Chinook helicopter crash, and connections to the Iran/Contra scandal . . . if you haven't read any of the McKinty's books, start with The Cold Cold Ground and make your way from there.
