Oh now this is why you should have read Kathy Reichs books! I'n reading deja dead at the moment and it is the only one i have not read and most of her stories are based in Montreal! (It's the author that the character in Bones is based on)
The way she descibes the city it is very very hot in the summer - certainly in this book i am reading, she descibes the cafe life on the Rue St catherine very well and there seem to be amazing deli s and bread shops too! It must be the Fench influence. the churches feature alot in it too.
