Agatha Christie, the best-selling author in 20th century

Agatha Christie was a mystery writer who was one of the world’s top-selling authors with works like Murder on the Orient Express and The Mystery of the Blue Train.

She was born on September 15, 1890, in Torquay, Devon, in the southwest part of England and she was educated at home by her mother, who encouraged her daughter to write.

In 1926, she released The Murder of Roger Ackroyd, a hit which was later marked as a genre classic and one of the author’s all-time favorites.
