When Lyn Dawson disappeared in 1982, many suspected her husband Chris Dawson had something to do with it. But for 40 years, the case went nowhere and Chris was free to live his life. All that changed when journalist Hedley Thomas entered the picture. Hedley unleashed a story of murder, sexual exploitation, failed criminal investigations, and later, a movement to put Chris behind bars. Hedley Thomas joins Crime Story to discuss Lyn’s case and his hugely influential podcast investigating it, The Teacher’s Pet.
