From New Statesman:
“Darkness at Noon” (1940) dramatises the Moscow show trials and Stalin’s “Great Purge” of Old Bolsheviks. In his review for the New Statesman, Orwell praised Koestler’s “inner knowledge of totalitarian methods”: “The common people,” argues the Party operative Gletkin, “cannot grasp ‘deviation’ is a crime in itself; therefore crimes of the sort they can understand – murder, train-wrecking and so forth – must be invented.” Many see Rubashov’s confession as a direct influence upon Winston Smith’s.
Orwell used his review as an opportunity to chastise the left-wing press in Britain for their refusal to speak up; a powerful statement made two years after Kingsley Martin refused to publish his despatches from Spain, fearing they would appear critical of Stalin, and therefore socialism: “What was frightening about these trials was not that they happened – for obviously such things are necessary in a totalitarian society – but the eagerness of Western intellectuals to justify them.”
Mr Arthur Koestler should know something about prison, for he has spent a respectable proportion of the past four years there. First a long stretch in one of Franco’s fortresses, with the sound of firing squads ringing through the walls twenty or thirty times a day; then a year or so of internment in France; then escape to England, and a fresh internment in Pentonville – from which he has just been unconditionally released, however. In no case, needless to say, has he been accused of any particular crime. Nowadays, over increasing areas of the earth, one is imprisoned not for what one does but for what one is, or, more exactly, for what one is suspected of being. Still, Mr Koestler can congratulate himself on having hitherto fallen only into the hands of amateurs. If England imprisoned him, it at any rate let him out again, and did not force him beforehand to confess to poisoning sheep, committing sabotage on the railways or plotting to assassinate the King.
