Charles Dickens may be lauded by many as the greatest Victorian novelist, but one close friend did not demur from fierce criticism after the writer’s death.

Wilkie Collins, the author of The Woman in White, collaborated on drama and fiction with Dickens and the two enjoyed a long, close friendship until Dickens’s death in 1870.
