Elsie is an 81-year-old woman living a quiet, isolated life on Kenny Lane in Melbourne. Standing six feet tall with a sharp tongue, she uses her abrasive personality to keep neighbors at a distance. During her childhood, she was branded "Mad Mabel" and convicted of murder at age 15, a history she fiercely protects from her community. Despite her curmudgeonly exterior, she harbors deep protective instincts toward the vulnerable.

Elliott is Mabel's father, a wealthy man whose primary affection is directed toward his grand Edwardian estate, Rosehill, rather than his family. He uses his social standing to manipulate public opinion, deliberately cultivating rumors about his daughter's mental stability. His emotional cruelty isolates Mabel and creates a toxic environment within the family home.

Daphne is Elsie’s childhood friend who originally returns from England precisely when Elsie needs her most. She possesses an exuberant personality and provides unwavering loyalty during Mabel's darkest moments. Her continuous presence offers Elsie a vital connection and represents the steadfast platonic love that helps her survive a hostile environment.

Persephone is the seven-year-old daughter of Roxanne, living across the lane from Elsie. She is persistent, talkative, and seemingly unfazed by Elsie's gruff demeanor. Desperate for connection, she continuously inserts herself into Elsie's daily routine, slowly breaking down the older woman's emotional barriers.

Peter, affectionately known as "Pete the Greek," is a kind and steady presence on Kenny Lane. He consistently defends Elsie against neighborhood gossip and offers his assistance without demanding anything in return. He treats the women on the street with respect and provides a calming influence during crises.

Roxanne is a single mother working night shifts as an office cleaner to support herself and her daughter, Persephone. She frequently moves to escape her abusive ex-partner, Shane. Exhausted but determined, she forms a cautious alliance with Elsie to help ensure Persephone's safety.

Joan is a litigious and highly suspicious neighbor living on Kenny Lane. When she discovers a news article about Elsie's past, she quickly assumes the worst and reports her concerns to the police. Her rush to judgment creates significant legal and social trouble for Elsie following the death of another neighbor.

Cecily, known as Cess, is Mary's younger sister and Mabel's aunt. She defies the gender expectations of her time by wearing slacks, smoking, and openly opposing Elliott's tyrannical behavior. She steps in as a fiercely protective surrogate parent for Mabel, offering a model of strength and defiance.

Vanessa, known as Ness, is a librarian and Cecily's devoted companion. She provides Mabel with intellectual nourishment and emotional warmth, giving her a copy of *Anne of Green Gables*. Her gentle encouragement helps Mabel find solace in literature and journaling.

Mary is Mabel's mother, a woman trapped in an unhappy marriage to Elliott. She struggles with severe emotional volatility and relies heavily on alcohol to cope with her isolation. Her brief moments of maternal care are frequently overshadowed by her erratic behavior and despair.

Shane is Persephone's father and Roxanne's abusive former partner. He relentlessly tracks Roxanne down despite restraining orders, posing a physical threat to both his family and the residents of Kenny Lane who stand in his way.

Adeem is a young, earnest documentary filmmaker who co-hosts the true-crime YouTube channel 'AdLib.' He approaches Elsie's history with curiosity rather than immediate judgment, seeking to understand the person behind the sensational headlines.

Libby is an investigative journalist and co-host of the 'AdLib' channel. She is persuasive and professional, offering Elsie a platform to share her unedited story with the public while maintaining a respectful distance.

Mr. Loukas is a young history teacher at Mabel's school who presents himself as a sympathetic confidant. He uses his position of authority to initiate an inappropriate and predatory relationship with the isolated teenager.

Christos is a Greek classmate who treats Mabel with respect when others bully her. He offers her genuine companionship and defends her against neighborhood tormentors, becoming a rare source of positive connection in her youth.

Ishaan is an elderly neighbor on Kenny Lane whose sudden death attracts police attention. He is widely disliked by his neighbors, and his unkempt property and barking dog are frequent sources of irritation for Elsie.

Billy is a neighborhood boy who leads the local children in isolating Mabel. As he grows older, his bullying escalates into cruel rumors and sexual harassment, heavily influenced by the toxic public opinion surrounding her.

Katharine, called Kitty, is Mabel's younger sister who died of polio at age one. Her death becomes a foundational tragedy for the family, one that Elliott falsely blames on a young Mabel to foster resentment and secure his own control over the household narrative.

Susan is a glamorous, platinum-blond woman who engages in an affair with Elliott. Her presence accelerates the disintegration of Mabel's family and demonstrates Elliott's complete disregard for his wife's well-being.

Tessa is Mr. Loukas's fiancée, entirely unaware of his predatory behavior until a confrontation forces the truth into the open. Her realization of his actions leads to severe consequences for the community.

Bailey is Joan's nephew and a partner at a law firm. He provides professional intervention when Elsie is questioned by the police, demonstrating how neighborhood resources can shift to protect vulnerable residents.
