Spanish Testament is a 1937 book by Arthur Koestler, describing his experiences during the Spanish Civil War. Part II of the book was subsequently published on its own, with minor modifications, under the title Dialogue with Death (see below). Koestler made three trips to Spain during the civil war; the third time he was captured, sentenced to death and imprisoned by the Nationalist forces of General Franco. Koestler was working as an espionage agent on behalf of the Comintern and as an agent of the Second Spanish Republic's official news agency, using for cover accreditation to the British daily News Chronicle.
The book was published in London by Victor Gollancz Ltd. The 'Contents' of the book is in two parts: Part I describes the context in which he was captured, divided into IX chapters, each with its own title. Part II, titled Dialogue with Death, describes Koestler's prison experiences under sentence of death. This part was written in the late autumn of 1937 immediately after his release from prison, when the events were still vivid.[1]
In the second volume of his autobiography The Invisible Writing, written by Koestler fifteen years later, the following footnote appears:
In all foreign editions, including the American, Dialogue with Death appeared as a self-contained book. In the original English edition, however (Gollancz and Left Book Club, 1937), it formed the second part of Spanish Testament the first part of which consisted of the earlier propaganda book on Spain that I had written for Muenzenberg. Spanish Testament is (and shall remain) out of print; Dialogue with Death has been reissued in England under that title, in the form in which it was originally written.[2]
