Instant New York Times bestseller. From New York Times bestselling author Sally Hepworth comes a twisty tale of justice, redemption, and one irrepressible woman who's not done breaking the rules just yet. Meet Elsie Mabel Fitzpatrick: eighty-one years old, gloriously grumpy, fiercely independent, and never without a hot cup of tea or a cutting remark. She minds her own business in her quiet Melbourne suburb until a neighbor turns up dead and the whispers start flying. Because Elsie hasn't always been Elsie. Once upon a headline, she was Mad Mabel Waller, Australia's youngest convicted murderer. But was she really mad, or just misunderstood? Either way, she's kept her secret buried for decades. Enter seven-year-old Persephone, a relentless little chatterbox who has just moved in across the road, armed with stickers, questions, and no sense of personal boundaries; Joan, who appears to have it in for Elsie; and a healthy dose of public interest—the cops are sniffing around, and the media is circling like seagulls at a picnic. So Mabel does what she's always done best—she takes matters into her own hands. Is she a cantankerous old lady with a shady past, a cold-blooded killer with arthritis, or just someone who's finally ready to tell her side of the story? Sharp, surprising, and wickedly funny, this is the unforgettable story of a woman who's spent a lifetime being underestimated—and is about to prove everyone wrong. Again.
