On a snowy night in Manhattan, a chess player from Washington Square Park shows up at his friend's office, bleeding. After being taken to the hospital, he then mysteriously disappears.Martin and Monika follow the clues left behind by Butch in the form of chess puzzles, as they become embroiled in an underground drug empire, and unlock the secrets of their friend's past.
The chess puzzles are first rate. I appreciated having more story this time. My only complaint about the puzzles is that it slowed down my reading of the book because I would usually take a while on each (still working on my chess prowess). If you like chess and mysteries, this is one to check out. (full disclosure - Kevin and I went to high school together and when we played chess he would start without his queen to make it fair. I hope I could win with that handicap now, but we would have to play again to tell).
