Review: The Mushroom Tapes by Helen Garner, Chloe Hooper and Sarah Krasnostein

The Mushroom Tapes by Helen Garner, Chloe Hooper and Sarah Krasnostein book cover

The Mushroom Tapes - Conversations on a Triple Murder Trial
by Helen Garner, Chloe Hooper and Sarah Krasnostein is about the trial of Erin Patterson, accused of three counts of murder and one count of attempted murder. Charged with serving her family members a lethal lunch of beef Wellington in Leongatha in July 2023, the trial took place in Morwell in April - July 2025 where she was eventually found guilty.

I followed the news coverage of Erin Patterson’s trial quite closely and listened to every episode of the Mushroom Case Daily podcast on the ABC. For these reasons and more, I was deeply interested in the collaboration between these three Australian writers having read books by all of them.* Familiar with Helen Garner's penetrating coverage of murder trials I was also fascinated to know the types of conversations these women had on a topic I never seem to tire of.

The Mushroom Tapes is a slim offering at only 240 pages so immediately you know you're not going to get a comprehensive coverage of the trial. What surprised me on the very first page though was that the authors weren't in attendance at the beginning of the trial. They'd been asked if they were going to cover the trial and they each said no. All three authors equally hadn't wanted to write about the case and hadn't not wanted to write about it. 

However after they heard the evidence from Simon Patterson's Aunt Heather Wilkinson that the guests ate from grey plates and the host ate from an orange one, they changed their minds and were galvanised into action. Helen Garner said that she didn't want to follow another big trial by herself and was glad to be asked to work with Chloe; accomplished herself with two trials and two books to her name. On day five they decided to cover the trial together and piled into the car to Morwell.

In the early stages, the women weren't sure whether they were collaborating to write a book or produce a podcast so they recorded their conversations with a view to deciding later and it shows.

Sharing the duties of sitting in the courtroom and listening to the live testimony in Melbourne via media audio-link, the reader is given snippets of conversations taking place in the car to and from court or over the phone. Often reading like a script, the effect made me feel as though I was in the car with them but without hearing their full experience.

These conversations ranged from how they felt standing outside Erin Patterson's house to the Defence Lawyer's potential advice to the defendant regarding a guilty plea; noting that if her lawyers know Patterson is guilty they can't make arguments inconsistent with that as they have a duty to the court.
"Most charges end up resolving in a guilty plea. But the personality that commits a crime like this is the same personality that believes they can get away with it." Sarah, Page 77
Every intellectual discussion the authors had about the case was of interest, including the conversation about whether the defendant might have a personality disorder and whether she was envious of the love shown to her children by their father and grandparents.

Shockingly, Helen has learned from attending family murder trials that just because you love someone doesn't mean you don't ever want to kill them; a statement which caused me to stop and ponder. It seemed to me the authors believed Patterson was guilty as they considered the difference between remorse and regret:
"Helen: Raimond Gaita says that remorse is a pained, bewildered realisation of what it means to have wronged someone. Sarah: Regret is self-interested. Remorse is a deeper thing." Page 134
Analysing Patterson's conduct in the witness box, they note that she's been unable to maintain a job, study or relationship for any sustained period of time despite having every resource, intellectual and financial at her disposal. They comment on her ability to unsettle them and notice that there's 'some force sheeting off her.' While they do discuss her persona and her false self, I was surprised they never talked about the family estrangements with her sister and her parents, and if they did, I'd love for it to have been included in the book.

I wasn't surprised to read that Patterson disagreed with every single witness but fascinated to hear that she talked back to the Prosecutor Nanette Rogers SC when being questioned on the witness stand with semantic critiques like these:
"Sorry, I was confused by the double negatives," and "You're going to have to rephrase that, so I know what you're talking about." Pages 200-201
I can't even imagine delivering that amount of snark or attitude in a Police interview room, let alone if I was in the witness box on trial for murder.

The authors often reflect on the huge scale of the media following this trial, their feelings on their own involvement and the incredible global interest in this case:
"Two hundred and fifty-two journalists and outlets are on the court media's daily email list, including representatives from fifteen international media outlets. There are seven podcasters, seven documentary crews, one television drama series and nine authors, including us." Page 140
Growing up in Gippsland, it's hard to fathom the sheer level of interest this case has generated and the authors often try to determine what it is about the murders and murderer that has captured this level of attention.

When acknowledging the closing arguments for the Defence by Colin Mandy SC, I was reminded of his address to the jury:
"If you think that it's possible that Erin deliberately poisoned the meal, you must find her not guilty... If you think that maybe Erin deliberately poisoned the meal you must find her not guilty. If you think that she probably deliberately poisoned the meal, you must find her not guilty." Page 209
Recalling this coverage brings a chill down my spine as I feared the jury would find Patterson not guilty after hearing it. When discussing her guilt or innocence, Helen acknowledges this as one of the most brilliant performances she's ever seen in her life while Sarah agrees Patterson is a liar but that liars can still be not guilty of murder.

Discussing what they would do in the event of a hung jury, Helen was clear that she wouldn't want to do anything with the tapes and would walk away from the project. Sarah mentioned she would be incapable of not attending a potential retrial while Helen would feel glad to escape one and doesn't want to write something that's going to attract the defendant's animus or attention.

Late in the book during the jury deliberations, they acknowledge that the podcast they'd started making has fallen over and that sometimes it feels as though the book they're still loosely imagining might do the same. This indicates to me that there was no clear plan at the outset and that one failed to emerge during the trial. And what's with the book cover? I was fortunate to purchase a copy signed by each of the authors but I thought it was the advanced reader's copy when I first saw it in the publisher's catalogue.

But most disappointing of all was the fact that there was no discussion or reflection on the verdict or the sentencing at all! The reader is privy to the verdict and the sentencing by Justice Beale, but then that's it. Without their thoughts on the verdict and the all important sentencing, The Mushroom Tapes feels unfinished. And perhaps it is.

True crime enthusiasts looking for a thorough or comprehensive summary of the trial will need to look elsewhere, perhaps to one of the seven podcasters, seven documentary crews or nine authors also covering the case. I had enough interest in this collaboration and Helen Garner's perspectives to keep reading but I was ultimately disappointed and wanted so much more from The Mushroom Tapes. I'd even be keen to listen to the raw footage!
