A novel in Andrea Camilleri's Inspector Montalbano mystery series, set in the fictional Sicilian town of Vigàta, follows two intertwined investigations: a contemporary weapons-trafficking operation and a 50-year-old double murder discovered in a hidden cave.
Inspector Salvo Montalbano, a sharp but stubborn police detective who prefers working alone, receives a summons through his childhood friend Gegè Gullotta, a small-time drug dealer. Gaetano "Tano the Greek" Bennici, a powerful Mafia fugitive, wants to meet Montalbano alone and unarmed. At a hilltop cottage, Tano explains that younger, ruthless men are pushing him out, and he wants to be arrested rather than killed. They negotiate a staged capture: Montalbano's men storm the cottage so it appears Tano was taken by force. Montalbano confesses the arrangement to the commissioner of Montelusa, the provincial capital, who orders two reports: one fake to be leaked to potential moles, and one real to be locked in his safe.
Meanwhile, Montalbano investigates a bizarre robbery at a supermarket owned by Carmelo Ingrassia. A truck stolen days earlier was used to clean out the store, yet the stolen goods were left in the abandoned vehicle. Ingrassia insists the whole thing was a practical joke. Gerlando Misuraca, an 84-year-old war veteran with the honorific title
cavaliere, writes to Montalbano that he saw Ingrassia's distinctive car near the supermarket during the robbery. Before Misuraca can testify, he dies in a car crash on a steep hillside. Montalbano's friend Ingrid, a Swedish woman married into a wealthy Sicilian family and a skilled mechanic, examines the wreck and determines the brake cable was deliberately cut, confirming Misuraca was murdered.
When Tano is fatally wounded during a botched prison transfer, he whispers the location of a weapons cache to Montalbano before dying. The inspector leads his team to the Crasticeddru, a rocky spur near Vigàta, where they find a cave concealed by a massive boulder. Inside lies a vast arsenal: machine guns, pistols, bazookas, explosives, and police uniforms. Montalbano reconstructs the trafficking route: Weapons arrive at the Brancato wholesale company in Catania, are packed in labeled crates, and travel by truck to Vigàta, where they are unloaded at the cave before the truck continues to Ingrassia's supermarket with legitimate deliveries. The staged robbery was an improvisation after a nearby shoot-out forced the truck to bypass the cave with weapons still aboard.
Montalbano pursues both cases simultaneously, causing friction with his deputy, Mimì Augello, who accuses Montalbano of systematic exclusion. Montalbano relents and assigns Augello to monitor the weapons case.
Reviewing footage of the emptied cave, Montalbano notices the back wall is made of stacked stones rather than natural rock. Headmaster Burgio, a retired local educator, explains that the boulder-door was built around 1941 by Giacomo Rizzitano to store black-market goods during the war. Burgio's close friend Lillo Rizzitano, Giacomo's grandson, disappeared during the 1943 Allied bombing. An echo sounder confirms a second cave behind the wall. When the team breaks through, they discover two mummified bodies on a rug, a man and woman in an embrace. Arranged around them are a bowl of 1940s coins, an earthenware jug, and a life-size terra-cotta dog lying in a watchful pose. The man has a bullet hole in his temple.
The coroner determines the victims were very young, killed by gunshots approximately 50 years earlier, and brought to the cave after death. Burruano, the wartime mayor of Vigàta, identifies the terra-cotta dog as part of a life-size Christmas nativity scene he commissioned in 1942. The coins date to before October 1943, when Allied military currency replaced them.
Signora Angelina Burgio, the headmaster's wife, reveals that her close friend Lisetta Moscato, Lillo Rizzitano's cousin, disappeared during the war. Lisetta's father, Stefano Moscato, a violent man with criminal convictions, claimed she ran off with an American soldier and sent Angelina a wedding photo. Montalbano suspects the photo is a photomontage, and a photographer confirms it: Lisetta's face was grafted onto another bride's body.
Montalbano identifies Lisetta's lover as Mario Cunich, a sailor stationed in Vigàta aboard the
Pacinotti, a naval repair ship. A former crewmate confirms Cunich went missing on July 7, 1943, and was in love with a local girl named Lisetta. Records show Stefano Moscato was imprisoned from March 1942 to April 1943, the period when the couple could have freely fallen in love.
Visiting Alcide Maraventano, a former priest who voluntarily left the priesthood, Montalbano learns the cave arrangement is not a burial rite but a coded message. In Mazara del Vallo, Tunisian teacher Farid Rahman explains the eighteenth
sura, or chapter, of the Koran, which describes young believers put to sleep by God in a cave with a dog guarding the entrance. The bowl with coins matches the
sura, but the jug does not. Professor Riccardo Lovecchio in Palermo resolves the puzzle: The jug corresponds to the Christian legend of the Seven Sleepers of Ephesus, which features a spring inside the cave. Only someone with academic knowledge of all variants could have combined both elements. Montalbano discovers that Lillo's 1942 university thesis concerned a mystery play about the Seven Sleepers, confirming Lillo staged the cave scene.
Before Montalbano can pursue Lillo further, the weapons case turns deadly. At a midnight meeting on the beach, Gegè warns that the Mafia believes Tano's arrest was staged and is targeting everyone involved. Assassins open fire, killing Gegè instantly. Montalbano kills one attacker and wounds another but takes a bullet in his side. During his hospital recovery, he learns that Ingrassia has been assassinated and that Corrado Brancato, the Catania wholesaler, and his wife have been killed by a bomb at their country house, obliterating the trafficking trail. Montalbano also discovers that Augello placed officers on Ingrassia's tail without authorization, inadvertently alerting the supermarket owner and triggering the attack.
After his release, Montalbano devises a plan to flush out Lillo, whom he suspects is still alive. He has Ingrid hire an advertising airplane that, during a motorbike race near the Crasticeddru, trails a banner reading "LISETTA AND MARIO," drops rose petals over the cave, and scatters strips of paper reading "LISETTA AND MARIO ANNOUNCE THEIR REAWAKENING." In a televised interview, Montalbano names the terra-cotta dog "Kytmyr, an Arab dog," a detail only someone who knew Rizzitano's thesis would recognize.
For days, Montalbano waits by the phone, growing obsessive and unkempt. On the fifth morning, Lillo Rizzitano calls from Palermo airport and arrives at Montalbano's home: a tall, nearly blind old man. He reveals he never changed his name or used false documents, having simply severed all ties to Sicily. He tells the full story. On July 6, 1943, Lisetta arrived at his house having been raped by her father, who had discovered her love letters from Mario. Mario came the next day. On July 9, while Lillo was away, Stefano Moscato sent a hired killer who shot Mario in the head and Lisetta in the heart as they slept. Returning home, Lillo found the gunman and beat him to death with an iron bar. In a state of horror and denial, he carried the lovers' bodies into the second cave and arranged them according to the sleepers legend from his thesis: the jug from the Christian tradition, the bowl of coins and dog from the Koranic version. If they were merely sleeping, he told himself, the horror had never happened. That night, bombs destroyed his house. Wounded, he was carried away by retreating soldiers and never returned to Sicily.
Rizzitano asks Montalbano to act as if he never came, and the inspector agrees. Before resting, the old man shows him a photograph of his youngest granddaughter, also named Lisetta, who looks identical to the murdered girl. As Rizzitano falls into a deep, peaceful sleep, Montalbano places a stuffed toy dog at the foot of the bed, then closes the door softly behind him.
