The walls of Mahatma Gandhi’s tiny room at Valmiki Mandir on Mandir Marg carry several pictures of towering leaders, including Frontier Gandhi Khan Abdul Ghaffar Khan, Pandit Jawaharlal Nehru and Sardar Vallabhbhai Patel. Among them is a sepia-coloured photograph in which Gandhi is seen talking to Pamela Mountbatten, the young daughter of India’s last Viceroy, Lord Louis Mountbatten. She regularly attended his all-faith prayer meetings and listened to his messages of non-violence and unity.
