Three signed letters from Arthur Koestler to Kenneth Cohen, one of which contains a copy of a letter from Koestler to a woman named "Anita". The letters sent to Cohen relate mainly to this "Anita" and her situation after the selling of her coffee shop, to Koestler's trip in Austria in 1969, and to this book The Scum of the Earth. The letter to Anita relates to the sale of her coffee shop, to the RUSI Journal, to the preface of the Danube edition of The Scum of the Earth, and to Rüdiger von Etzdorf, who helped Koestler to escape North Africa and return to the UK at the beginning of the Second World War.
