Award-winning author Greg Haddrick will be in conversation with Michael Brissenden on Greg's new book The Mushroom Murders.

A family lunch. Three deaths. What really happened? The shocking story of a weekend lunch laced with a highly toxic mushroom, and a triple murder trial that gripped the world, shattered a family and gave a mother a life sentence.

On 29 July 2023, Erin Patterson hosted a family lunch at her home in the small regional Victorian town of Leongatha. She had invited her parents-in-law, Don and Gail Patterson, and Gail's sister, Heather Wilkinson, and her husband Ian. Erin made beef Wellington for her guests, individual beef eye fillets covered in mushroom paste, wrapped in pastry. The following day, all four guests were taken to hospital, and Heather, Gail and Don died. Ian Wilkinson barely survived. A toxicologist found traces of the highly poisonous death cap mushroom in the remains of the meal.

At first, it appeared to be a dreadful accident. As the police investigation continued, the evidence mounted, seeming to point one way. Yet Erin Patterson spun a web of lies, and steadfastly claimed she did not intend to harm her relatives.

Greg Haddrick tells the fascinating inside story of the dramatic murder trial, and the forensic evidence that convinced the jury to convict a suburban mother of a gruesome triple murder. With many details not previously revealed in the media, it is the compelling story of a troubled family and the world's most poisonous mushroom,.
