Lynette Dawson vanished from her home in Sydney in 1982

So begins the true-crime podcast The Teacher's Pet. 

Investigated and written by journalist Hedley Thomas, the series focuses on an Australian missing persons case that was all but ignored by police when it first surfaced back in the 1980s.

A wife vanishes into thin air, a husband replaces her with a teenager he had been sleeping with, two young kids start calling this girl their mother, and seemingly, no one bats an eyelid.

Here are six key reasons why you should, and need to, listen to The Teacher's Pet ASAP.

1. You've heard this story before

It's one everyone knows - the one where the famous, good-looking, well-respected man might have been involved in something dodgy, but nothing ever comes of it because he's well-connected.

Chris Dawson may as well have been famous in Bayview that's how untouchable he was. Not only were a lot of male teachers adamant that he couldn't hurt a fly, but he was also mates with friends of the police around the time of his wife's disappearance.

Sound familiar? It should.

2. And yet at the same time, you've never heard anything like this story before 

Just when you think The Teacher's Pet has thrown all it can at you, there's another twist or an extra piece of information that'll make you reconsider everything you thought you knew about the case.

The troubling details shared by Chris's young student lover, Joanne, in her police interview are told with such a calm clarity you'd almost be forgiven for forgetting she was talking about a man who groomed her from such a young age.

It wasn't just Joanne who was in a sexual relationship with her teacher either.

There were many others - some of whom are still now dealing with the psychological effects of their past experiences as part of the alleged sex ring.

3. Chris Dawson always denied murdering his wife

Lyn's husband Chris always denied having anything to do with his wife's disappearance but was found guilty of murdering her in 2022.

The former high school teacher was sentenced to 24 years in prison after the podcast triggered a new investigation.

4. The case was solved in 2022 

The case of Lyn's disappearance was reopened again in the 1990s when many of the key players were interviewed, but up until the launch of the podcast, there had been very little movement.

Since then, however, there has been significant attention paid by Australian police and the justice system - so much so that the show has been removed from podcast platforms in Australia for reasons that you'll understand once you listen to it.

In 2018, the cold case was reopened after the podcast put pressure on the investigators.

5. More and more witnesses came forward

Unlike a lot of true crime pods that are all recorded in one go, The Teacher's Pet was constantly updated.

Many witnesses contacted journalist Hedley as the podcast went on. He provided the listener with new information that otherwise would have been unavailable.

This trend continues throughout the series as more and more people contact The Australian with tips and stories about Lyn and Chris.

The case was unfolding in real-time.

6. It's yet another case of a woman in trouble being let down by the system 

And because of that, it deserves to be heard.

If listeners were to believe Chris Dawson's version of events that his wife left her family to join a cult and has simply decided to not contact anybody for over 30 years, this is still a case of a woman who disappeared without a trace.

In 1982, police took Chris at his word that his wife had decided to leave her family behind.

Whether Lyn left or was murdered, her disappearance should have garnered more attention than it did.

In 2022, he was tried without a jury because of the major publicity the case attracted.

Dawson killed his wife so he could pursue his relationship with a teenager.

Lynette Dawson's body has never been found.
