Stephen Alter was raised by American missionary parents in the hill station of Mussoorie, in the foothills of the Himalayas, where he and his wife Ameeta, now live. Their idyllic existence was brutally interrupted when four armed intruders invaded their house and viciously attacked them, leaving them for dead. The violent assault and the trauma of almost dying left him questioning assumptions he had lived by since childhood. For the first time, he encountered the face of evil and the terror of the unknown.
The sleepy Himalayan hill station of Mussoorie, near India's border with Tibet, is home to an eclectic mix of residents including Tibetan refugees and former guerrilla fighters, foreign missionaries, Indian military, tourists, and spies. Here, in a top-secret facility facing the snow-clad Himalayas, India's legendary spymaster, Colonel Imtiaz Afridi, keeps a watchful eye on sensitive high-altitude borders.
