The Picture of Dorian Gray

 was a best-selling novel written by Oscar Wilde.

While its central character, a man who never aged due to a supernatural portrait in his attic that aged in his stead, was widely considered to be a fictional creation of Wilde, there was a man who claimed to be the real Dorian Gray, and who was indeed immortal. (AUDIO: Shades of Gray) He was an acquaintance of Sherlock Holmes, another person who was often thought to be fictional, and met the famous detective on more than one occasion, including once in 1927. (AUDIO: The Feast of Magog) Centuries later, he met Bernice Summerfield. (AUDIO: Shades of Gray)

Sgt Quick had read the novel when he met Wilde but Henry Gordon Jago had not. (AUDIO: Beautiful Things)

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)

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!)
