1984: The masterpiece that killed George Orwell

'It was a bright cold day in April, and the clocks were striking thirteen.'

In 1946 Observer editor David Astor lent George Orwell a remote Scottish farmhouse in which to write his new book, Nineteen Eighty-Four. It became one of the most significant novels of the 20th century. Here, Robert McCrum tells the compelling story of Orwell's torturous stay on the island where the author, close to death and beset by creative demons, was engaged in a feverish race to finish the book.
