The Picture of Dorian Gray

The premise is Wilde's most perfect inversion of the Gothic double: instead of a hidden monstrous self erupting to destroy a respectable surface, Dorian's surface stays perfect while the monstrous self is literally painted elsewhere, hung behind a curtain, growing uglier with every cruelty he commits. That split lets Wilde run his aestheticist argument, that beauty and morality are separate registers, that art answers only to beauty, and simultaneously refute it: the whole plot is a demonstration that you cannot actually separate them, that the ledger keeps itself somewhere whether you look at it or not.

Lord Henry is the novel's real corrupting force, and Wilde gives him the wit rather than the moral authority — every epigram he tosses off is delightful and genuinely dangerous, style operating as a delivery mechanism for a philosophy that costs Sibyl Vane her life and turns Dorian, who starts merely vain, into someone who murders Basil for confronting him and blackmails Alan Campbell into disposing of the body. Basil's death is the hinge: he's punished not for painting the portrait but for still believing, as its creator, that Dorian could be shown himself and repent it. Basil is the last person in the book who thinks Dorian has a conscience worth appealing to, and he's wrong in exactly the way that gets him killed.

The novel was used as evidence against Wilde at his 1895 trials, prosecutors reading Basil's infatuation and Henry's epigrams as confessions rather than fiction — an irony Wilde's own aestheticism, the claim that a book is well or badly written and nothing more, couldn't protect him from in a courtroom that read every line as autobiography. The novel that argues most explicitly for separating art from morality became evidence for collapsing that separation entirely, used to try the author for the tastes of his characters.
