There are too many writers of noir fiction in Scotland, and they're too diverse, to sum up in a single article. There's Peter Turnbull (police procedurals of a high standard by a former social worker who knows the streets, novels set in Glasgow if I remember correctly); Ian Rankin (my interest in him is growing, due to several recommendations from writers like Deon Meyer as well as a couple of pretty good BBC series made from his books--though when I read them the first time around, his novels, set in Edinburgh, didn't engage me much); Denise Mina's bleak novels of an underclass dependent on anti-depressants; Christopher Brookmyre's thrillers (the best of them are perhaps too funny to be really noir); Val McDermid is Scottish (don't know if she still lives there, though), and her novels are certainly very dark; then there's Douglas Lindsay, whom I haven't read (hard to find in U.S.) but I hear he's "darkly funny," as they say; and there's the series (several books anyway) by William McIlvanney, featuring Jack (I think that's his first name) Laidlaw--and these are the most purely, classically noir novels set in Scotland that I know of (though I'm for some reason usually less interested in organized crime villainy, very prominent in these books, that individual criminals).
There's also a large crop of mystery novels set in Scotland, more of the cosy or middle-class mystery variety than noir, going back many years--in comparison to the noir novels listed above (and their ilk) this stuff is very Nancy Drew, to me--Alex Gray or Simon Brett, for example.
What do you think? Have I missed any "real" noir novels of Scotland? Let me know--and let me know what you think about Douglas Lindsay--should I be investing in the overseas shipping to get his books?
