Dumb Witness by Agatha Christie [Paperback]

In Agatha Christie’s Dumb Witness, elderly spinster Emily Arundell suffers a fall in her country home, which is initially blamed on a rubber ball left by her playful terrier. However, Emily grows suspicious, believing that one of her relatives is trying to kill her. On April 17th, she writes a letter to Hercule Poirot, outlining her fears. But mysteriously, Poirot doesn't receive the letter until June 28th—by which time Emily has already died, allegedly from natural causes. Sensing foul play, Poirot begins investigating, uncovering hidden motives and secrets within Emily's family.
