The Last Anniversary

Every family has a founding myth. It’s the story told at holidays, the one that explains how they all came to be. For some, it’s a tale of immigration and sacrifice. For others, it’s a whirlwind romance that led to a wedding six weeks later. These stories become the bedrock of a family’s identity, a shared legend polished smooth with each retelling. But what happens when that bedrock is built on a lie? What if the official story—the one that has defined generations, built a small fortune, and become a beloved piece of local folklore—is a complete fabrication? The truth doesn't just sit quietly in the past; it exerts a gravitational pull on the present, warping relationships and creating unspoken tensions that everyone feels but no one can name. Living inside such a story is like living in a house with a secret room everyone pretends isn't there.

This is the exact kind of tangled, domestic puzzle that fascinates Australian author Liane Moriarty. She has built a career exploring the quiet, often hilarious, and sometimes devastating secrets lurking beneath the surface of ordinary suburban lives. Moriarty began her writing life in the world of advertising before turning to fiction, where she found her niche examining the intricate psychologies of family and friendship. For The Last Anniversary, she was drawn to the idea of a 'perfect' family story that was just a little too perfect to be true. She wanted to explore how a single, seventy-year-old secret could ripple through time, shaping the choices, fears, and loves of people who weren’t even alive when it was first told, creating a captivating mystery wrapped in her signature blend of wit and warmth.

Module 1: The Architecture of a Family Secret

The novel is built around a central, foundational lie. It’s known as the Munro Baby Mystery. In 1932, sisters Connie and Rose Doughty supposedly found an abandoned baby in a house. The baby's parents, Alice and Jack Munro, had vanished without a trace. This story becomes the origin myth of Scribbly Gum Island. It also becomes the family's primary source of income.

The first key insight is that family secrets often begin as desperate solutions to immediate problems. The Munro Baby Mystery was a brilliant, desperate invention. A fourteen-year-old girl named Rose was pregnant. She had been raped by her boss. In the 1930s, this was a life-destroying scandal. Her older sister, Connie, was fiercely protective. She refused to send Rose away. So, Connie created the entire mystery. She invented the vanished parents. She staged the scene with a warm marble cake and a boiling kettle. This fabrication saved her sister from shame. It also allowed them to keep the baby, Enigma.

This leads to a powerful second point. A successful lie must be meticulously maintained and commercialized. Connie built an empire on the story. She turned the abandoned house into a tourist attraction. She established the "Anniversary," an annual event commemorating the disappearance. This event became the island’s economic lifeblood. The family’s identity became inseparable from the lie. They weren't just the Doughtys. They were the keepers of the Munro Baby Mystery. The secret became a brand.

But here's the thing about long-held secrets. They create a psychological burden that ripples through generations. Enigma, the baby at the center of the myth, grows up with a manufactured identity. She sees herself as a celebrity, the "Munro Baby." Her entire life is defined by a story that isn't true. Her children, Margie and Laura, and grandchildren, Veronika and Grace, inherit this complex legacy. Veronika becomes obsessed with solving the mystery. She suspects her great-aunt Connie was a murderer. Grace, on the other hand, feels a strange disconnect from her family's lore. The secret creates anxiety, suspicion, and a web of carefully managed information. There’s even a family rule. The truth is only revealed to family members when they turn forty. This ritualizes the deception. It turns the secret into a controlled, generational handoff.
