Dialogue with Death, a book by Arthur Koestler, was originally published in 1937 as a section (Part II) of his book Spanish Testament, in which he describes his experiences during the Spanish Civil War. Part II of the book was subsequently decoupled from Spanish Testament and, with minor modifications, published on its own under the title Dialogue with Death (see quotation below). The book describes Koestler’s prison experiences under sentence of death. The book was written in the late autumn of 1937 immediately after his release from prison, when the events were still vivid in his memory.
