William Wilkie Collins (1824–1889) was a very popular Victorian novelist and a close friend and collaborator of Charles Dickens. Collins was a prolific writer, publishing not only novels, but many plays, short stories, and works of nonfiction. Collins sold his first short story at 19, and his first novel at 24. Collins had a very successful career as a master of suspense with a distinct narrative voice, filled with social commentary. Wilkie Collins never actually practiced law, but his knowledge profoundly impacted his writing and he is considered one of the godfathers of the detective novel.
