'The Book of Air and Shadows' is not really a literary mystery. It's a regular mystery whose plot features a literary icon. I'm enjoying the mystery aspect, but I must admit that when the story centers on a potentially undiscovered Shakespeare autograph manuscript, I would like the meat of the story to be a little more worthy of the idea it's trying to sell. In this vein, I prefered 'Codex' by Lev Grossman and 'The Rule of Four
' by Ian Caldwell and Dustin Thomason.
