Cleo Laine, one of England’s most acclaimed jazz singers and an actress who had a memorable Broadway turn as the proprietor of a London opium den in “The Mystery of Edwin Drood,” died on Thursday at her home in Wavendon, England. She was 97.

Her death was confirmed by her daughter, Jacqui Dankworth.

Ms. Laine, who was known for a smoky voice that she could deploy over a four-octave range and for her skillful scat singing, recorded numerous albums across six decades. She won a Grammy Award in 1986 for best female jazz vocal performance for “Cleo at Carnegie: The 10th Anniversary Concert.” She and her husband, the saxophonist and bandleader John Dankworth, performed all over the world and in various settings ranging from intimate nightclubs to the London Palladium.

Ms. Laine’s interests were wide ranging. She had small roles in a handful of movies, in several of which she was credited simply as “Singer.” She performed in operas. She worked pop songs into her act. And she was drawn to the theater, especially musical theater.

Her performance as Princess Puffer in “The Mystery of Edwin Drood,” based on an unfinished Charles Dickens novel and staged as a nightly murder mystery in which the audience votes on the culprit, earned her a Tony nomination in 1986, as well as a number of murder indictments.

She didn’t mind the criminal record, but she joked in a 1985 interview with The New York Times that one thing about the role gave her pause. “It certainly can’t do my career any harm,” she said, “unless everybody says from now on, ‘Get Cleo Laine for the old hag. She’s very good as an old hag.’”
