It is concert night for the New York Luminoso Chorus, and the conductor is behaving strangely. When a leading soprano is found dead backstage, arts reporter Piper Morgan rushes to the scene and covers the murder for The New York News. The next day, a dispute over two identical music manuscripts erupts in the chorus, drawing Piper to the plight of a forgotten 19th century composer, Lisha Lovington, whose unheard Requiem will soon be premiered by the chorus. Did Lovington plagiarize the famous composer rumored to be her lover? If so, the conductor has vowed to strike her name from the music. Searching Lovington’s old letters for evidence, Piper finds a bombshell —a hundred-year-old coverup that, if revealed, would rock today’s music world. Then a second chorus member is murdered, and Piper realizes her quest for the truth could kill her.
