The Mysterious Affair at Styles is a detective novel by Agatha Christie. It was written in 1916 and was first published by John Lane in the US in October 1920 and in the UK by The Bodley Head (John Lane's UK company) on February 1 1921. This story is, to the best of my knowledge, in the public domain as I acquired this audio book from a source that makes public domain audio books available on the internet.
