Who among the following has written 'Vanity Bagh', which is based on the life…

In 'Books and Authors' questions, each celebrated literary work belongs to exactly one writer, and that authorship is a fixed biographical fact established by publication records and literary prizes -- not something inferred from an author's general reputation or themes.

'Vanity Bagh' (2013) is a novel by Anees Salim. It is set in a locality called Vanity Bagh, home to a minority community, and follows Imran Jabbari, a young sign-painter drawn into a bomb-blast case despite having no part in the crime. The book won The Hindu Prize for Fiction, announced in January 2014 at The Hindu Lit for Life festival, recognising the best fiction published in 2013.
