Arthur Koestler, Darkness at Noon.

Arthur Koestler made his international breakthrough as a writer with Darkness at Noon (1940), a novel set against the background of the Moscow trials. The contrasting background and lettering (Bodoni Ultra and Ultra Italic) of this 1943 fourth impression contains favourable reviews of the first edition (a scarce book because copies were destroyed by a fire in the warehouse) as well as war-time propaganda plugs on the back flap: 'Britain calls the World ...From London comes the Voice of Britain. The Voice of Freedom.'
