"The Case of the Ten Little Black Men", also known as "And Then There Were None", is a famous detective novel by Agatha Christie, published in 1939. The story follows ten strangers invited to an isolated island, Soldier Island, under various pretexts. Once there, a recording reveals that each guest has a dark past and was responsible, directly or indirectly, for another person’s death, though none faced punishment.

The plot unfolds with tension and mystery as the characters are killed off one by one, following an old nursery rhyme about "ten little soldiers", which predicts the order and manner of their deaths. With no means of escape or communication with the mainland, the group falls into despair, trying to discover who among them is the murderer before they are all eliminated.

With a narrative full of suspense and twists, *The Case of the Ten Little Black Men" explores themes of justice, guilt, and paranoia, and is one of Christie’s most celebrated and successful mysteries.
