Hallowe'en Party: A Hercule Poirot Mystery
Brand: Audible
At a Hallowe'en party, Joyce - a hostile thirteen-year-old - boasts that she once witnessed a murder. When no one believes her, she storms off home. But within hours her body is found, still in the house, drowned in an apple-bobbing tub.

That night, Hercule Poirot is called in to find the "evil presence". But first he must establish whether he is looking for a murderer or a double murderer.
