How many novels did Oscar Wilde write?

The Picture of Dorian Gray is the only novel written by Oscar Wilde. It was panned as immoral by Victorian critics, but is now considered one of his most notable works.

The Picture of Dorian Gray is a Gothic and philosophical novel by Oscar Wilde, first published complete in the July 1890 issue of Lippincott's Monthly Magazine. Fearing the story was indecent, the magazine's editor deleted roughly five hundred words before publication without Wilde's knowledge. Despite that censorship, The Picture of Dorian Gray offended the moral sensibilities of British book reviewers, some of whom said that Oscar Wilde merited prosecution for violating the laws guarding public morality.

In response, Wilde aggressively defended his novel and art in correspondence with the British press, although he personally made excisions of some of the most controversial material when revising and lengthening the story for book publication the following year.
