The Kamogawa Diner sits down a quiet Kyoto street, easy to miss unless you already know it's there. Chef Nagare Kamogawa serves each guest a set menu of his own choosing before showing them into the back room, where his daughter Koishi runs what she calls a detective agency — not for crimes, but for lost recipes.
Across six linked stories set through the changing seasons, an Olympic-hopeful swimmer, a single mother and food writer, a grieving couple, and other visitors each arrive with a half-remembered dish and a reason they need to taste it again: for closure, for insight into a decision, or simply to hold onto someone they've lost. Nagare and Koishi track down the memory behind the meal — sometimes from a scrap of an old shopping list, sometimes from nothing more than a description of how it smelled — and recreate it exactly.
Quiet and episodic rather than plot-driven, the novel treats food as a way back into memory, family, and the choices that come after loss.
