Sydney, 1982. Lyn Dawson is a young mother who disappears without a trace. No body. No note. Just a husband, Chris Dawson, who quietly moves his teenage student — the family babysitter — into the house within weeks.

The Teacher's Pet, hosted by journalist Hedley Thomas, spent years digging into what police couldn't close. The podcast became a phenomenon, pulling in tips, witnesses, and old friends who'd stayed silent for decades. Thomas's reporting didn't just retell the case — it actively reshaped it, pressuring authorities to take another look at a disappearance everyone had written off as unsolvable.

Chris Dawson was eventually convicted of Lyn's murder in 2022, a conviction that came directly out of the renewed attention this series generated — proof that podcasts can do more than entertain. But even with a conviction on record, Lyn's body has never been found, and the family is still searching for that final piece.
