Dumb Witness

📗 When Hercule Poirot discovered the truth of the Dog's Ball incident, he became convinced that Emily Arundell did not die from natural causes. Who, then, was responsible for the death of this rich spinster? Could it be: the slightly wanton Theresa, her spendthrift brother Charles, Wilhelmina Lawson, the seemingly meek companion, Bella Tanios - married to a Greek doctor her aunt distrusted, or those irritating Tripps with their infernal seances? Unlike Poirot the murderer forgot the tongue of the "Dumb Witness".
