In “Nocturne for a Widow,” actress Sybil Ingram inherits a Gothic mansion with a hostile ghost and a maddeningly gorgeous tenant after her wealthy American husband dies. As she battles the ghost and the insolent Roderick Brooke, a greater threat emerges in the form of the mysterious Mrs. Lavinia Dove, making for a delightful fusion of gothic romance, mystery, and comedy. Join Sybil in her continuing adventures in “The Last Serenade,” “A Haunting Reprise,” and the short stories “Spectral Strains” and “Christmas at Gravesend.”
