There's a terrific article in the archives of The Independent newspaper in the UK: "Around the World in 80 Sleuths":

From Greenland to New Zealand, Thailand to Paris, Los Angeles to New York, Northern Ontario to London ... and 72 other places in between ... one sleuth per stop, please.
As if your TBR pile isn't high enough already!
