Night Train to Jamalpur

North East India, 1923. On the broiling Night Mail from Calcutta to Jamalpur, a man is shot dead in a first class compartment. Detective Inspector Jim Stringer was sleeping in the next compartment along. Was he the intended target? Jim should have known that his secondment to the East Indian Railway, with a roving brief to inspect security arrangements, would not be the working holiday he had hoped for. The country seethes with political and racial tension. Aside from the Jamalpur shooting, someone is placing venomous snakes - including giant king cobras - in the first class compartments of the railway.
