To my surprise, it's not pulp fiction. Kamala Markandaya was a noted author, and this is her most autobiographical novel. In the book, the freedom struggle gets in the way of a rather stilted, upper class romance between Richard and Mira. In real life, Kamala Markandaya married a British man shortly after independence, and made her home in London.
Another of her novels, The Nowhere Man - about an elderly brahmin marooned in a south London suburb - has just been republished by Penguin India. Anybody know it?
