"London, England 1925. A Russian prince. A wealthy heir. An impoverished earl's daughter. Which one will make an untimely exit from the London social scene? Scotland Yard Detective Inspector Devenand Hunter finds himself in the middle of a series of upper-class deaths in London. Bright Young People are being extinguished in their favorite night spots, from a sleazy private jazz club to the Savoy ballroom. Dev knows just the person to help him navigate the treacherous society waters: Lady Adelaide Compton, a marquess' daughter and widow of a Great War hero. Unfortunately, he has put her in jeopardy once before, nearly leading him to turn in his warrant card. But when her sister Cee is nearly one of the victims, Addie turns to Mr. Hunter, offering her help... and it soon becomes clear that the two of them working together again could lead to much more than merely solving crime." --,(Source of summary not specified)
