‘Pen, Pencil, and Poison’ is one of Wilde’s most intriguing essays. Part biography, part social commentary, and part philosophical debate, he writes the biography of an art critic, who was also convicted of murder. However, in true Wildean style, there’s more to the essay than meets the eye. While documenting the life and crimes of Thomas Griffiths Wainwright, Wilde explores the ideas of dual identity, sin in the formation of the personality, and the relationship between crime and culture. ‘Pen, Pencil, and Poison’ is a fascinating insight into some of the conventions of the time.
