In the glittering shadows of Paris, Lieutenant Yves Moreau disappears into a new identity-Adrien Noir-an undercover agent sent to infiltrate the world of Rocco Valère, a seductive art dealer whose masked soirées conceal a darker trade. What begins as an operation becomes an obsession. Behind Rocco's opulence lies a secret ledger, a network of missing children, and a mark worn only by men who have surrendered their souls.
As Adrien's mission deepens, desire and duty blur. Every glance becomes a question, every touch a risk. Haunted by his mother's death and his father's cruelty, Yves finds in Rocco a mirror of his own brokenness-a man both predator and prisoner of power. When the truth finally surfaces, the chase turns inward, and survival demands the ultimate disguise: becoming someone else.
UNO: Only One Came to Play is a taut psychological thriller that explores seduction, trauma, and the cost of identity. Set against the intoxicating beauty of Paris Fashion Week and the moral decay beneath its art scene, it asks: How far will you go to keep your secrets-and what happens when the mask fits too well?
For readers of Patricia Highsmith, Andre Aciman, and Garth Greenwell, UNO is a haunting descent into love, deceit, and the dangerous illusion of control.
