Set in the hallucinatory glow of 1920s Piccadilly Circus, this psychological noir follows Richard Gunn, a starving WWI veteran pulled into a lethal reckoning for a past crime. Hugh Walpole masterfully blends the grit of urban poverty with high-stakes suspense, exploring the 'Lost Generation' through a conflict between moral idealists and predatory cynics. It is a haunting, cinematic journey through the shadows of London, where the line between heroism and madness is razor-thin.
