Because of my love of Root Beer, I'm on the Cybercandy email list. They supply sweets and drinks from all over the world and in the current newsletter there is an advert for Finnish sweets:
"It's not just about Salmiakki and salty liquorice! Finnish Candy is not to everyone's tastes but when we're low on stock a lot of you never Finnish letting us hear about it."
Browse and order from Cybercandy online or visit one of their shops in London, Birmingham or Brighton.
If Finnish crime fiction is more your thing, then check out the authors listed on the Euro Crime website.
