The Sign of the Seven Sins

The Sign of the Seven Sins by William Le Queux is a novel written in the early 20th century. It appears to be a romantic-sensation mystery set on the Riviera, where Monte Carlo’s glitter conceals a web of crime, secrets, and temptation. Narrated by the young American-Italian Carmela Rosselli, the story entwines her travels with her worldly friend Ulrica Yorke, a sudden murder, an enigmatic millionaire, and a masked figure called “The Owl,” hinting that love, money, and danger will collide. The opening of the novel follows Carmela from Washington to London, Paris, and finally Nice, where she and Ulrica fall into the Monte Carlo orbit with two American acquaintances, Gerald Keppel and Reginald Thorne. After a lucky afternoon at roulette and a glittering dinner at Ciro’s—during which Carmela glimpses her former lover Ernest Cameron with another woman—Reggie wins a fortune, steps away to change his notes, and is later found dead in the women’s hotel sitting-room, the cash gone and the cause unclear. The police inquiry yields nothing but suspicion and press sniping, while Carmela and Ulrica draw closer to Gerald’s austere, eccentric father, the millionaire Benjamin Keppel, who secretly turns ivory and proposes a yacht cruise. As Carnival peaks, a masked “Owl” dances with Carmela and seeks a private audience, declaring he knows the truth about Reggie’s death and insisting robbery was not the motive.
