Matthew Parris meets Suzanne O'Sullivan to discuss her medical and literary hero, Oliver Sacks.

She first came across his work on a beach in Thailand, reading his famous collection of case studies, The Man Who Mistook His Wife for a Hat. Joining the discussion is Sacks' partner, the writer and photographer Bill Hayes. Together they discuss the career of a gifted medic and writer who also loved motorbikes and wild swimming. Sacks wrote another extraordinary book, Awakenings, which was made into a film starring Robin Williams and Robert de Niro.

Suzanne O'Sullivan is an Irish neurologist and award winning author.
