The second volume of the remarkable autobiography of Arthur Koestler, author of Darkness at Noon. Taken together, Arthur Koestler's volumes of autobiography constitute an unrivalled study of a twentieth-century life. The Invisible Writing picks up where the first volume, Arrow in the Blue, ended, with Koestler joining the Communist Party.

This second volume goes on to detail some of the most important, gruelling and electrifying experiences in his life. This book tells of Koestler's travels through Russia and remote parts of Soviet Central Asia and of his life as an exile. It tells of how he survived in Franco's prisons under sentence of death and in concentration camps in Occupied France and ends with his escape in 1940 to England, where he found stability and a new home.
