In 1841, Nigel Halleck left Britain as a clerk in the East India Company. He served in the colonial administration for eight years before leaving his post, eventually disappearing in the mountain kingdom of Nepal, never to be heard from again.

A century-and-a-half later, Kief Hillsbery, Nigel's nephew many times removed, sets out to unravel the mystery. Tracing his ancestor's journey across the subcontinent, his quest takes him from Lahore to Calcutta, and finally to the palaces of Kathmandu. What emerges is an unexpected personal chapter in the history of the British Empire in India.
