H is for Halloween Party by Agatha Christie

One of my cousins bought the hardcover edition of this book for my grandmother the year she got indoor plumbing. Good reading material while she waited for her turn in the new bathroom. But I digress…

Blurb: (from Goodreads) A teenage murder witness is drowned in a tub of apples… 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…
