Peter Diamond, head of the Criminal Investigation Division in scenic Bath, England, is investigating the murder of a young woman whose body has been found in the canal, the only clue to her identity a tattoo of a music note on one of her teeth. For Diamond, who wouldn’t know a Stradivarius from a French horn, the investigation is his most demanding ever.
 
Meanwhile, strange things are happening to jobbing violist Mel Farran, who finds himself scouted by a very elite classical quartet—one whose previous violist disappeared without a trace. Despite the mystery shrouding the group, the chance to join is too good to pass up, and Mel finds himself in a cushy residency at Bath Spa University with the quartet--and embroiled in the unusually musical murder investigation. As the story unfolds in fugue-like counterpoint, Peter and Mel both learn frightening secrets about fandom and about what it takes to survive in the cutthroat world of professional musicians.
 
Peter Lovesey has been hailed by the critics as "superlative," "a master of the genre," "never puts a foot wrong" and the Peter Diamond series as "one of the most enjoyable police series around." This new case for the much-loved detective will bring new praise and much satisfaction for his legions of fans.
