A visitor came and left a parcel outside the room in which Orwell was lying alone. Sometime early on Saturday morning, an artery burst in his lungs, and a few moments later he was dead, aged 46. Controversy surrounds Sonia's activities. Some say that she was at a nightclub and inaccessible. Others claim that at the end of the evening having had dinner with her friends, she called the hospital and came back distraught with the news of Orwell's death.

David Astor lived in Sutton Courtenay, Oxfordshire, and arranged for Orwell to be interred in the churchyard of All Saints' there.

At this time, he was severely ill; it was wartime or the austerity period after it; during the war his wife suffered from depression; and after her death he was lonely and unhappy. In addition to that, he always lived frugally and seemed unable to care for himself properly. As a result of all this, people found his circumstances bleak. Some, like Michael Ayrton, called him "Gloomy George", but others developed the idea that he was an "English secular saint".

She had not given Orwell much notice about this operation because of worries about the cost and because she expected to make a speedy recovery.
