Which he did. His research stretches out across his living room in a disordered chaos of books, files and folders and he can happily quote chapter and verse on any period of Wilde's life. And as Wilde's reputation has been restored in the last 25 years from an infamous but essentially lightweight Victorian epigrammatist to serious literary figure, so Holland's own standing has grown with it. His new volume of more than 1,500 letters, which updates the long-since out-of-print Rupert Hart-Davis edition with 300 previously unseen letters, is the culmination of his work to date. "I think it is only through the letters that you get to see the real Wilde," he offers, "the man of contradictory impulses; the married homosexual, the writer who hated writing, the humility and the arrogance, the barbed and the kind." Contradictory impulses may be a family trait. For someone who does not want to be labelled Oscar's keeper, Holland has had some very public spats with those whose vision of Wilde does not coincide with his.
