Tartufo

In a dying medieval village perched on a Tuscan hilltop, a truffle buried beneath the soil of a chestnut forest releases its intoxicating scent into the wind. The pheromones drift into Lazzarini Boscarino, reaching the nose of Aria, a Lagotto Romagnolo truffle-hunting dog sitting in Bar Celebrità, the village's last surviving social hub.

The village is in steep decline. Its ristorante, pasticceria, and café have all shuttered. Bar Celebrità's owner, Lorenzo Micucci, confides to its boisterous bartender, Giuseppina, that the bar may not survive the winter. Giuseppina, whose estranged husband, Chef Umberto, runs a celebrated restaurant in the rival town of Borghese, longs for vitality to return. Other residents include Giovanni Scarpazza, Aria's quiet owner and a truffle hunter; farmer Leon Rosetti, whose wife Sofia has been missing for six days; Duccio Berardinelli, the disgraced postman; Padre Francesco, the village priest; and Nonna Amara, the beloved 86-year-old matriarch whose home was half-destroyed by a landslide three years earlier. Giuseppina mentions that a psychic named Mamma Fortuna predicted a special visitor would come to the village, followed by a death and then untold riches, though Giuseppina cannot remember the psychic's final prediction.

Delizia Micucci, a former veterinarian who recently became the village's first female mayor, holds her inaugural council meeting and carries a devastating secret: Her late father, Mayor Benigno, embezzled 500,000 euros of government funds and donations meant to save the village. Unable to confess this, she lies, calling the debt minor. The council also discusses Nonna Amara's predicament, for which Carlotta, a local nonagenarian, and two companions pool 463 euros, a generous but insufficient sum against the 2 million euros needed for repairs.

Giovanni takes Aria and his apprentice puppy, Fagiolo, into the forest to hunt truffles. Memories surface: His father kicked him out for loving his partner, Paolo. Nonna Amara took him in and raised him. Paolo eventually died, leaving Aria as a parting gift. After Aria finds several standard truffles, she freezes, signaling something extraordinary. Giovanni unearths a white truffle of staggering size, far exceeding any ever recorded. Overwhelmed, he tries to smuggle it home, but Fagiolo's antics blow his cover in the village piazza. Giovanni decides to trust his community, reveals the truffle, and declares it belongs to the village.

Delizia determines they must sell the truffle through Chef Umberto, despite Lorenzo's bitter objections: Umberto betrayed his brother years earlier by stealing family recipes and funds. At Umberto's restaurant, the truffle weighs 6 pounds, 14 ounces. Umberto offers 100,000 euros, but Giuseppina arrives and confronts her estranged husband. Their exchange reveals two people still deeply in love. Giuseppina insists the proceeds go entirely to the village, and Umberto relents, agreeing to connect Delizia with his auction contacts instead.

Delizia arranges a video meeting with Sotheby's in New York, but the call nearly collapses: She is alone in the crumbling town hall with no Wi-Fi and a goat that wanders in following the truffle's scent. Umberto arrives late and saves the meeting. Sotheby's confirms the truffle appears to be the world's largest and agrees to an auction at an 11th-century castle on the village hilltop.

Global media descend, digging into local secrets: Sofia's disappearance, Duccio's prison time, Padre Francesco's alleged excommunication from a church in Rome. Rico Valentino, president of the rival Borghese Tartufi truffle company, confronts Giovanni aggressively. During the altercation, someone steals Giovanni's Jeep with Fagiolo inside. A harrowing chase ends when the thief crashes and escapes on foot. Fagiolo is unharmed, but Giovanni vows to withdraw from the village and its truffle madness.

Meanwhile, Nonna Amara teaches her granddaughter Vittoria, who is nearly 12, to make chestnut ravioli. Vittoria hides a consuming anxiety: Since the landslide nearly killed Nonna, she has become obsessed with protecting her grandmother. When they visit Nonna's damaged property, Vittoria secretly takes a key to Nonna's shed, setting in motion events that will surface later.

That night, Giovanni enters the church crypt, believing that returning the truffle to the forest will end the madness engulfing the village. The hidden key is missing, and he hears shoes clicking on the stone below. He retreats and takes his dogs into the woods, where Aria leads him to Sofia's body, face down in the leaf litter. Meanwhile, Delizia checks the crypt and finds the truffle gone.

The next morning, the villagers gather at Leon's farm to mourn Sofia. Leon reveals he had been finding and pouring out hidden bottles of alcohol, and the apparent cause of death emerges as liver failure from chronic alcohol use. Giovanni connects the shoe sounds in the crypt to Padre Francesco's hard-soled footwear. The villagers rush to the church and find the priest at the altar, holding the truffle over holy water in an attempted exorcism. Giovanni warns that moisture will destroy it. The truffle is inspected and found undamaged.

Giuseppina, desperate to learn Mamma Fortuna's forgotten final prediction, races to the psychic in the coastal town of Pietrasanta. Mamma Fortuna delivers a new warning: There will be a battle with a ghost, someone will seek vengeance, and if Giuseppina does not intervene, there will be another death.

The auction unfolds spectacularly. Celebrities, media, and ultra-wealthy bidders fill the castle's grand hall. Bidding escalates through a dramatic duel between Rino Ricco, an infamous confectionary heir, and Elyse Zhang, an agent representing an anonymous buyer, until Rino Ricco wins at 3 million euros.

Moments later, a Vespa painted in the colors of the Italian flag roars into the hall. The helmeted driver grabs the truffle and races for the exit, but Al Pacino, the village cat whom Rico threw out of the castle earlier, leaps in front of the Vespa. The driver swerves and crashes, shattering the truffle across the gravel. The driver is revealed to be Rico Valentino. Young Vittoria tearfully confesses that she had been secretly riding a Vespa taken from Nonna's shed to Borghese, selling her belongings to raise money for Nonna's house repairs. Rico stole the vehicle from where she parked it. Nonna comforts Vittoria and clasps a silver Saint Christopher necklace around her neck.

That night, Delizia receives word that Leon's donkey, Maurizio, is in medical distress. She diagnoses an intestinal blockage from ingested plastic and treats him through the night. While waiting in the stable doorway with Leon, she watches a wolf step into the moonlight, and the encounter fills her with a profound sense of belonging. Ludovica, her stepmother, approaches with genuine warmth for the first time, and Delizia begins to forgive the painful past her father left behind.

Maurizio recovers, and the villagers celebrate his 22nd birthday at Bar Celebrità. Silvio, Carlotta's grandson and the village policeman, secures Rico Valentino's arrest after drone footage links Borghese Tartufi to the earlier theft of Giovanni's Jeep. Umberto prepares to apologize to Lorenzo and propose they collaborate. Delizia holds an unshared secret: Her nomination for the village to become a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site has been accepted for evaluation. Vittoria has started an online cooking show with Nonna Amara that generates revenue to fund house repairs. A young writer arrives, drawn by the truffle story but captivated by the village itself, and tells the villagers "your village might be the true truffle." The novel closes with a passage mirroring the prologue: Deep beneath the soil, another enormous truffle has ripened and released its scent, waiting to be found.
