The Somali prisoner, the secret language and the life-saving book

Mohamed Barud was losing hope in a Somali prison, when an inmate in a neighbouring cell devised a secret language and tapped out the Russian novel Anna Karenina through his wall... for Mohamed, the book was transformative. He tells his story to Emily Webb. Mohamed wrote a book about his experience called The Mourning Tree.
