Meet the forensic pathologist, Dr Richard Shepherd, in the true crime book of the year - brought to you by Penguin.
'The dead do not hide the truth and they never lie. Through me the dead can speak....'
He solves the mysteries of unexplained or sudden death.
He has performed over 23,000 autopsies, including investigating 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 disasters, '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.
Written and narrated by Dr Richard Shepherd, 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.
