Meet the forensic pathologist, Dr Richard Shepherd.
He solves the mysteries of unexplained or sudden death.
He has performed over 23,000 autopsies, including some of the most high-profile cases of recent times; the Hungerford Massacre, the Princess Diana inquiry, and 9/11.
He has faced serial killers, natural disaster, ‘perfect murders’ and freak accidents.
His evidence has put killers behind bars, freed the innocent, and turned open-and-shut cases on their heads.
Yet all this has come at a huge personal cost.
Unnatural Causes tells the story of not only the cases and bodies that have haunted him the most, but also how to live a life steeped in death.
