Shame "Anonymous" is no longer with us, as I'd like to mention author Leif G.W. Persson, who has written a series of comic-mystery novels about the Swedish police. Like Nordic Noir but with gags. (Swedish humour, though: some of it is universal humour but some of it doesn't travel well)
The appalling detective Evert Bäckström is first introduced as a minor character (and black comedy relief) in the novel
Between Summer's Longing and Winter's End — The Story of a Crime (
Mellan sommarens längtan och vinterns köld), dramatised for TV as
En Pilgrims Död. He also appears in the sequel
Another Time, Another Life (
En annan tid, ett annat liv). The importance of these novels is that Persson was formerly a middle-high ranking civilian employee of the Stockholm police force: he was "invited to resign" after whistle-blowing on high level incompetence among the cops, and the suspicion you get on reading his police procedurals is that these are thinky veiled reality with names, dates and locations changed to prevent libel actions.
Mellan sommarens... is an account of a fictional Sweidsh Prime Minister who is murdered one evening in Stockholm - Persson is being as explicit as he dares with the fiction and using it to present his own theory that a far-right-wing conspiracy in the police killed Palme and covered up their inside job afterwards - and is still sabotaging any investigations that get too near the truth. (Don't forget Palme was quite highly placed in the Stockholm force)
The novel has been translated into English - it is very readable - and Swedish TV ran with it and dramatised it, the TV version (Swedish only,
Death of a Pilgrim) is out there on the Net. Article on Persson's writing HERE (it inspired the American TV adaptation which Americanises the characters but then goes its own way)
