When Eugenie Davies is killed by a driver on a quiet London street, her death is clearly no accident. Someone struck her with a car and then deliberately ran over her body before driving off, leaving nothing behind but questions. What brought Eugenie Davies to London on a rainy autumn night? Why was she carrying the name of the man who found her body? Who among the many acquaintances in her complicated and tragic life could have wanted her dead? And could her murder have some connection to a twenty-eight-year-old musical wunderkind, a virtuoso violinist who several months earlier suddenly and inexplicably lost the ability to play a single note? For Detective Inspector Thomas Lynley, whose own domestic life is about to change radically, these questions are only the first in an investigation that leads him to walk a fine line between personal loyalty and professional honor.
