In the picturesque village of Guzmán, Spain, in a cave dug into a hillside on the edge of town, an ancient door leads to a cramped limestone chamber known as “the telling room.” Containing nothing but a wooden table and two benches, this is where villagers have gathered for centuries to share their stories and secrets—usually accompanied by copious amounts of wine. It was here, in the summer of 2000, that former Zingerman’s employee Michael Paterniti found himself listening to a larger-than-life Spanish cheesemaker named Ambrosio Molinos de las Heras as he spun an odd and compelling tale about a piece of cheese. An unusual piece of cheese. Made from an old family recipe, Ambrosio’s cheese was reputed to be among the finest in the world, and was said to hold mystical qualities. Eating it, some claimed, conjured long-lost memories. But then, Ambrosio said, things had gone horribly wrong…

Hooked, Paterniti is soon fully embroiled in village life, relocating his young family to Guzmán in order to chase the truth about this cheese and explore the fairy tale-like place where the villagers converse with farm animals, live by an ancient Castilian code of honor, and make their wine and food by hand. But what he ultimately discovers is nothing like the idyllic slow-food fable he first imagined. Instead, he’s sucked into the heart of an unfolding mystery, a blood feud that includes accusations of betrayal and theft, death threats, and a murder plot. As the village begins to spill its long-held secrets, Paterniti finds himself implicated in the very story he is writing.
