In her 1977 , Christie confessed that she never thought that the play would be produced but that she simply enjoyed writing plays or writing something different from that which she was used to. There is no record of any serious attempt to get the play staged once it had been written, but Charles Osborne, in his book "The Life and Crimes of Agatha Christie" puts forward the theory that the publishers thought it not commercial, and was not what the public expected of Agatha Christie, who was seen at the time as purely a writer of crime fiction.
