London, 1935. The Music Hall on Grove Lane hospitably opens its doors to the most respectable public. Tap dancing on the wings of an airplane, magical illusions, a trained goose, dances, songs, numbers with instant transformation - the artists, sparing no effort, give the audience bright emotions. However, the troupe has been plagued by failures from the very beginning of the theater season. One dancer is injured, then another dies - and Philip Adamson, the troupe's entrepreneur, is forced to turn to his sister for help. This winter, Olivia Adamson will not only have to delve into the intricacies of behind-the-scenes intrigue, but also try herself in the role of an assistant to an illusionist and a police informant, and also save an innocent person from the noose by exposing the true criminal. But how to understand what feelings lie behind the smiles and bright makeup? How to recognize who is lying and who is telling the truth? The third book in the series about the investigations of the Adamson twins will appeal to fans of classic English detective stories. See you at the music hall on Grove Lane!
