Ten Little Niggers (1939) is regarded by many as her finest mystery and it is said to be the best-selling of her novels. But it also revealed Agatha Christie as hopelessly insensitive on racial matters (see the original book cover below left).
American publishers rejected the title and so Christie renamed it And Then There Were None, but later Broadway productions (1944-) undid this good deed by retitling it Ten Little Indians.
Worse, racist artwork persisted in the U.K. well into the 1980's (the book cover below right is from 1963 through 1981). At the time of writing this, you could find used copies of this book on Amazon UK. Was whoever designed (and approved) this Golliwog image back then for Fontana simply naive or were they simply cynical?
