Stoker was a deeply private man, but his almost sexless marriage, intense adoration of Walt Whitman, Henry Irving and Hall Caine, and shared interests with Oscar Wilde, as well as the homoerotic aspects of Dracula have led to scholarly speculation that he was a repressed homosexual who used his fiction as an outlet for his sexual frustrations. In 1912, he demanded imprisonment of all homosexual authors in Britain: it has been suggested that this was due to self-loathing and to disguise his own vulnerability. Possibly fearful, and inspired by the monstrous image and threat of otherness that the press coverage of his friend Oscar's trials generated, Stoker began writing Dracula only weeks after Wilde's conviction.
After suffering a number of strokes, Stoker died at No. 26 St George's Square, London on 20 April 1912. Some biographers attribute the cause of death to tertiary syphilis, others to overwork. He was cremated, and his ashes were placed in a display urn at Golders Green Crematorium in north London. The ashes of Irving Noel Stoker, the author's son, were added to his father's urn following his death in 1961. The original plan had been to keep his parents' ashes together, but after Florence Stoker's death, her ashes were scattered at the Gardens of Rest.
