A Fatal Overture is the third in Kathleen Marple Kalb’s wonderful mystery series set in New York City at the turn of the 20th century, featuring opera singer Ella Shane, a mezzo soprano “trouser diva,” known for singing male roles. Ella, the daughter of an Irish father and a Jewish mother, grew up in a tenement on the Lower East Side and was orphaned at an early age. The trauma of finding her mother’s body, frozen to death in their tiny room, has never truly left Ella. After being raised by her aunt on her father’s side of the family, Ella found a mentor, a famous opera singer, who discovered she had a great voice, and so, by the time the series begins, Ella has also become famous. She owns her own company and lives in a brownstone on Washington Square with her cousin Tommy, the son of the aunt who brought her up. Tommy, a former champion boxer, is a closeted gay man who manages her career and helps her fend off unwelcome admirers.
