London: Jonathan Cape, (1943).
Softcover. Uncorrected proof. Printed dull blue wrappers. Owner's tiny name on first leaf, a little erosion at the base of the spine, and the bottom of the first several pages a little creased, about very good. The final volume in Koestler’s trilogy on the revolutionary end justifying the means, which included *The Gladiators* (the story of Spartacus, published years before Howard Fast's treatment of the same material) and his classic, *Darkness at Noon*. Scarce in proof form.
