In 1966, John Barker, a dynamic psychiatrist working in an outdated British mental hospital, established the Premonitions Bureau to investigate psychic visions. He found a network of hundreds of correspondents, from clerks to ballet teachers – including two unnervingly gifted “percipients”. The New Yorker’s award-winning Sam Knight joins us with an enthralling true story of madness and wonder, science and the supernatural – a journal to the most powerful and unsettling reaches of the human mind.

Sam joins How To Academy in-person on the 7 June in conversation with the author of The Big Short and Flashboys, Michael Lewis. Find out more and get your tickets at howtoacademy.com
