Query: a truly fresh twist on the genre

A CLUE FOR THE PUZZLE LADY is a terrific book--wonderful plot complete with crossword puzzle clues, red herrings, and all sorts of twists and turns; fun and eccentric characters who are a hoot without going over the edge into unbelievability; snappy dialogue; great writing style. I couldn't put it down.
