Title: For Real Mystery Puzzle Lovers
Review: Although not the greatest mystery novel ever, Fog of Doubt (originally called London Particular) is a treat for puzzlers who really like to try to figure things out - not only is the last sentence an ultimate revelation, but there is also another major clue which does not reveal itself as a clue until the book is over. I'll say no more than that.
