Tom Tomaszewski works as a psychotherapist specialising in addiction at a private clinic, Charter, in central London. He was born in 1966 and grew up in South London, spending large amounts of time in the Scottish Highlands. His father, a printing engineer, came from a family of dissenting Polish patriots. His aunt died in Auschwitz and his grandfather was regularly prosecuted for an anti-Prussian column he wrote: Polish Fire. His mother, a nurse who worked with the Romany population of St Mary Cray in Bromley, introduced him to books and music alongside medicine and psychology, all of which continue to interest him. The Eleventh Letter is a story about desire, ghosts and trying to change the past.
