Dan is a popular dentist who has been donating his time to treat charity cases. This is in opposition to his partner, Jack Wagner, who feels it detracts from their high society profile. Dan's body is found burned in one of his many cars. The only identification is his dental records. Belle uncovers many possible suspects for his murder: his partner, his secretary, Bonnie and her brother, one of his charity cases, and Dan's wife herself.

Belle receives a number of anonymous crossword puzzles which seem to contain clues to Dan's murder. In addition to the help from Rocco she gains support from the New Castle group who meet every Saturday morning at the Lawson Coffee Shop. There red herrings and clues, both forensic and from the anonymous crossword puzzles, lead to the startling conclusion.

The dialogue with the Saturday morning group is witty and sharp. The story is full of twists and misleading clues. Is it really Dan? What part does Karen play in his disappearance? Has he really disappeared? If so, why? The relationship between Belle and Rocco is a happy one to observe.

As a bonus, a handful of crossword puzzles relating to the crime as well as a few others are included (complete with answers).

A challenging good read to pass a few pleasant hours.
