Sometimes you go out with friends and there’s something going on. Everyone’s talking about something and you don’t know what it is. The latest podcast, the new Netflix sensation or a bestselling book. Here’s my round-up of the things everyone is talking about and what they are all about, so that you can at least know what’s going on, if not join in the conversation.

Podcast: The Teacher’s Pet – now with over three million downloads and counting, this is Australia’s most-downloaded podcast. It is (so far) 11 parts and it investigates the disappearance of Sydney woman Lynette Dawson in 1982. Two coroners have found that Lynette is probably dead, and that her husband, Chris Dawson (former model, rugby league star and PE teacher) was probably her murderer. But Chris claims that he is innocent and the Office of the Director of Public Prosecutions has never brought charges against him. In addition to this, Chris Dawson had an affair with, and ended up marrying, one of his students from the high school he was teaching at. This is a tale of sadness, betrayal and mystery and the journalist who is making it, Hedley Thomas, is determined to get to the bottom of it. If you want to join in the dinner party conversations, start listening now. You won’t be able to stop.

Book: Eleanor Oliphant is Completely Fine – this book was selected for my book club pick last month. It’s the story of a lonely woman in Glasgow and a possible path out of her loneliness and towards healing for the trauma of her past. Eleanor is a straight-shooter who doesn’t quite understand the social norms of the world in which she lives, so this makes for some amusing commentary. This is an easy read, but it’s a sad story that is ultimately uplifting.

Guru: The Barefoot Investor. Scott Pape, or “The Barefoot Investor” isn’t new to Australia’s small screen. And he already has loads of followers online. But now his book has sold more than a million copies. So what’s it all about? Here’s the thing. It’s not actually about becoming a mogul/millionaire. It’s all about being sensible with your spending and saving and using home-spun, pragmatic strategies to grow your wealth. Like: don’t buy stupid things. And: make sure your everyday banking account does not have fees. And: avoid credit cards (and how to get on top of your debt). There’s nothing gimmicky here, but I found the advice invaluable and easy to follow. The book sells from $20-30 and it will pay for itself in no time.

Netflix: The Staircase. Another true-crime series, this is new to Netflix and has three new episodes following up on the family trailed by a French film crew back in 2004. The subject of the series is a writer called Michael Peterson, whose wife was found dead at the foot of their staircase. Did Michael kill her? Or was her death the result of an unfortunate fall? You’ll swing one way and another while watching this riveting and heart-breaking documentary. And you’ll be able to join in the chatter at your next girls’ night out.
