Summary
At a London auction, a Corot landscape painting becomes the unexpected nexus of intrigue, as Princess Sonia desperately vies with her estranged, exiled husband, Prince Victor, for its possession. Hidden within its canvas are incriminating letters penned by Sonia, vital to her freedom. However, the coveted artwork is acquired by Michael Lanyard, a shadowy figure whispered to be the enigmatic international thief, “The Lone Wolf.” Lanyard, with an unexpected gesture of chivalry, delivers the letters to Sonia, enabling her divorce from Victor and subsequent marriage to him. Their union is tragically brief, ending with Sonia’s death after bearing their daughter, also named Sonia. Years later, the younger Sonia, raised under the mistaken belief that she is the daughter of her mother's maid, is drawn into the sinister orbit of a re-emerged Prince Victor. Now the calculating leader of a formidable underworld syndicate, a dangerous alliance of Asian criminals and Bolsheviks, Victor lures the unsuspecting Sonia to his lair, feigning paternal affection, all while intending her presence to bait Lanyard out of obscurity. Unbeknownst to her, Victor harbors a chilling plot: to unleash poisonous gas upon Buckingham Palace and the residences of England’s elite, paving the way for his tyrannical dictatorship. When Sonia uncovers the monstrous conspiracy, she confides in Roger Karslake, Victor’s seemingly loyal secretary, with whom a romance blossoms. In a dramatic climax, both Lanyard, who has been operating deep undercover as Victor's seemingly subservient Asian butler, and Karslake are revealed to be Scotland Yard agents. Amidst a furious conflagration and a desperate struggle, the agents dismantle Victor’s treacherous gang, thwarting his calamitous ambitions.
