Paranoia, the collateral damage on his family and the investigations he makes into drugs used to treat such a breakdown: Horatio Clare talks to Laurence Scott about his Journey through Madness, Mania and Healing. Plus the poetry of Stevie Smith (20 September 1902 – 7 March 1971). Author of the much quoted lines Not Waving but Drowning; Stevie Smith suffered from depression and acute shyness. New Generation Thinker Noreen Masud looks at her writing.

Horatio Clare has recorded a series of different walks for BBC Radio 3. His books include The Light in the Dark: A Winter Journal; A Single Swallow; Down the Sea in Ships and his new memoir Heavy Light.
