The Good Left Undone

Set in the Italian seaside village of Viareggio, the story moves between the present day and the early twentieth century, tracing four generations of the Cabrelli family, artisan jewelers who have cut gems and fashioned sacred objects for the Vatican since the days of patriarch Pietro Cabrelli.

In the present, 81-year-old Matelda Roffo lives in the penthouse of Villa Cabrelli with her husband, Olimpio, a master gem cutter who runs the family's jewelry shop in nearby Lucca. Matelda's health is quietly failing. She struggles to recall a bedtime story her grandfather Pietro once told about an elephant hauling rubies from an Indian mine. When her 25-year-old granddaughter Anina Tizzi visits to choose a piece of heirloom jewelry for her wedding to fiancé Paolo Uliana, Matelda is seized by urgency to share the stories behind each piece before she forgets them or dies. Among the heirlooms, Anina discovers a dark green aventurine watch fob engraved "D & J." Matelda refuses to part with it, explaining it belonged to her mother, Domenica Cabrelli, who was a nurse. At a birthday dinner, Matelda's daughter Nicolina Tizzi brings an old photograph revealing that Domenica married twice: first to John Lawrie McVicars, a Scottish sea captain and Matelda's biological father.

The historical narrative begins in 1920, when 11-year-old Domenica enlists her best friend, Silvio Birtolini, to steal a library map and hunt for pirate treasure. Silvio is stigmatized as il bastardo because his mother bore him out of wedlock. During the chase that follows, a rock strikes Silvio above his eyebrow. Domenica takes him to Dottore Pretucci's clinic, where she cleans the wound and volunteers to sew stitches, revealing a natural aptitude for nursing. Silvio's mother decides to flee the village with her son to escape the bullying. The night before he leaves, Silvio brings Domenica bomboloni, filled Italian doughnuts, through her window, kisses her goodbye, and whispers that he will return someday. He and his mother leave behind a blessed medal of Santa Lucia, patron saint of vision.

Years later, Domenica earns her nursing credentials under Pretucci's mentorship. In 1939, she gives birth-control information to a young mother whose health is endangered by further pregnancies. The woman's husband, Guido Mironi, publicly confronts Domenica at the Carnevale festival, and the local priest threatens to revoke her license. Pretucci arranges for her to work at a hospital in Marseille until the scandal blows over. Her father gives her his gold pocket watch as she departs, insisting she carry something of value so people will recognize her worth.

In Marseille, Domenica befriends fellow nurses Stephanie Arlette, an American from Chicago, and Josephine Brodeur, a Jamaican. One night, Captain McVicars crashes through the hospital doors carrying an injured crewman. Domenica is immediately drawn to him. She triages his crew with calm authority, treats his burned hands, and earns his admiration. Over the following weeks they exchange letters, and McVicars returns for a day trip to Cassis, where they share their first kiss at a hilltop café.

Their courtship is disrupted when the hospital closes in anticipation of war. Domenica is transferred to a convent school in Dumbarton, Scotland, stung by a typed letter from McVicars coldly ending their correspondence. Unknown to Domenica, the letter is a forgery by McVicars's mother, Grizelle, who despises Italians and has been intercepting Domenica's letters, hiding them in a brick in the garden wall. McVicars eventually discovers the deception, reads all 13 hidden letters, and confronts his mother. He finds Domenica in Glasgow by chance, follows her onto a trolley, and begins regaining her trust.

McVicars proposes at the convent, presenting Domenica with the aventurine watch fob, a nurse's timepiece engraved "D & J." They marry on June 3, 1940, at a church in Manchester. Days later, Mussolini declares war on England and France, triggering the roundup of Italian nationals across Britain. Anti-Italian riots destroy shops in Glasgow. Italian men and boys are arrested as enemy aliens, among them the elderly Arcangelo Antica, the jeweler Amedeo Mattiuzzi, and Mattiuzzi's son Piccolo. McVicars is assigned as first mate on the Arandora Star, a requisitioned luxury liner wrapped in barbed wire, tasked with transporting the prisoners to internment camps. Before he ships out, Domenica clasps a medal of Our Lady of Fatima around his neck for protection. He smuggles food to his Italian friends housed below the waterline.

On July 2, 1940, a German U-boat torpedoes the Arandora Star off the coast of Donegal, Ireland. Nazi prisoners on the upper decks commandeer lifeboats and block the Italians from escaping. Antica, at 70, gives his life jacket to a teenage boy and lets the rising seawater take him. Mattiuzzi drowns. Piccolo survives by clinging to a wooden baluster. McVicars stands on the bridge as the ship sinks, kisses the Fatima medal, and goes down with the ship. His body washes ashore in Ireland and is buried in an unmarked grave. When Domenica visits Grizelle to request a photograph of John, his mother refuses. Domenica will never possess a single image of her husband.

Domenica gives birth to Matelda at the convent and waits five years for the war to end before returning to Italy. The Cabrellis' lifelong friends Romeo and Agnese Speranza, gem cutters from Venice, are deported in 1943. Romeo is forced to cut timers for Nazi bombs; Agnese is sent to Buchenwald, where she dies. After the war, Romeo sells his prized deep-red pigeon blood ruby to Silvio Cabrelli before dying peacefully.

In postwar Viareggio, Silvio returns as a skilled gem cutter and is hired by Pietro Cabrelli. He courts Domenica patiently, befriending young Matelda. On a moonlit walk, Domenica confesses she loved Silvio first, before McVicars. Silvio proposes with a ring he cut himself and asks to take the Cabrelli name, replacing the surname Italian law assigned to a fatherless boy. Domenica accepts and burns McVicars's letters in a Carnevale bonfire, releasing the past.

In the present, Matelda's storytelling transforms her family. Anina leaves Paolo after forgiving him for kissing another woman, recognizing she had wrongly made him her sole purpose. She moves into her grandparents' apartment and begins learning the jewelry trade, training on the bruting wheel, a gem-shaping tool used to cut and round stones. Matelda and Nicolina share a tender reconciliation when Matelda tells her daughter she has been wonderful, a compliment Nicolina says she waited 25 years to hear. Nicolina also reveals that Matelda once suffered a stillbirth, a daughter she named Domenica, explaining a lifelong grief. Matelda dies on the terrace watching the sea, whispering "Domenica" as she sees a vision of her mother on the beach. At the funeral, Nicolina reads Matelda's farewell letter and distributes the heirlooms: the aventurine watch to Anina and the Speranza ruby to Olimpio. Olimpio also finds a note from Silvio revealing that he changed the ending of the elephant story so the elephant lives, affirming that a family's strength lies in its stories.

In the epilogue, Anina and Olimpio travel to Glasgow, where they find McVicars's name on a memorial plaque for victims of the Arandora Star. Anina makes a rubbing of his name, revealing a tattoo of "Matelda" in her grandmother's handwriting on her inner arm. Back in Lucca, working alone at night, Anina cuts her first stone on the bruting wheel, committing to seven years of mastery as the fourth generation at Cabrelli's. In Karur, India, a boy digs in the red earth and discovers a pigeon blood ruby, shouting "Life!" as the circle of the prologue's story closes.
