Death Behind the Blue Door | A Hercule Poirot Mystery

A servant girl is found dead behind a blue door in the manor house—a door that's been locked for twenty years. No one has a key. No one remembers what lies beyond it. Poirot alone understands: sometimes the oldest doors hide the freshest secrets. And whoever killed her knew exactly where to hide the body.

A classic cozy murder mystery audiobook in the spirit of Agatha Christie.
