The Picture of Dorian Gray

 was a best selling novel written by Oscar Wilde.

Sgt. Quick had read it but Henry Gordon Jago had not. (AUDIO: Beautiful Things)

In 2013, Charlie Gibbs alluded to the novel when he said that Turlough must have had a "portrait in the attic" as he had not aged since 1983. In spite of this, Turlough believed that Gibbs had never read a book in his life. Nyssa did not understand the reference, but discerned it to be a literary one. (AUDIO: Eldrad Must Die!)

When Zoe Heriot was eight years old, she read Wilde's complete works, including The Picture of Dorian Gray, in a day. (AUDIO: Echoes of Grey)
