Henning Mankell's seventh book about Kurt Wallander: "On Step Behind" has a plot and a character (and possible pair of star-crossed lovers) of special interest to slashing fans:

Karl Svedberg, Wallander's good friend and colleague is implicated in a crime early on in the book, and much of the following plot focuses on secrets he has kept from Wallander. I bet you can guess where this is going? *drumroll* One Step Behind has canon angsty slash! *hugs the author*

( More details, huge spoilers and a picture behind the cut )

BUT why am I writing this? Because there is no fic! I haven't found a single one, neither on FF.net: Wallander nor on AO3: Wallander, nor anywhere else. Do you know better? Or, could I inspire you to make a go of it? Please post plotbunnies too: the right prompt does help a lot in greasing the cogs. ;)
