Lured to a frozen lake, Montreal detective Émile Cinq-Mars comes face to face not with the unknown woman who asked to meet him there, but with a corpse floating under the ice. Something tells him that his nose is being rubbed in this murder — and that this is about to get very personal. In this follow-up to the classic City of Ice, Cinq-Mars must determine the difference between would-be friends and deadly enemies — before it's too late.
