Through the Wall

A celebrated Parisian sleuth, Paul Coquenil, has long been the city’s go‑to mind for the most baffling crimes. After a sudden and mysterious retirement that left the press buzzing, he now finds himself summoned to head a foreign capital’s detective service—an offer too tempting for a man who once walked the streets of Rue de la Cité with a faithful shepherd dog at his side. The change promises a fresh arena for his razor‑sharp instincts, yet the shadow of his past still lingers in the cafés and alleyways he once patrolled.

When a cryptic, unknown girl whispers a phrase that only Coquenil seems to feel, a new case erupts—one that eclipses even the infamous Palace Royal diamond theft. The investigation spirals through bustling markets, the looming walls of the Prefecture, and secretive whispers in dim corridors, pulling the detective into a maze of intrigue, danger, and unexpected alliances. As the heat of a July Paris swelters, Coquenil must decide whether to follow his intuition or the cold logic of the law.
