Dom Moraes and Sarayu Srivatsa have written a book that is, at times, as eccentric and startling as the life story of Tom Coryate. The Long Strider is a lively, many-layered tale that turns out to be nearly as much about Dom as it is about its ostensible hero. The two authors, in antakshari mode, take it in turns to write chapters. Dom, writing as a novelist, recreates Coryate’s final years. Sarayu, writing as a diarist, records their modern-day search in England and India for traces of the world Coryate left behind. This is an ambitious exercise, and on the whole they pull it off.
