Mute Witness

'As trivial as it seems, I have felt increasingly frightened and insecure since the incident with our dog Bob's ball...' Miss Emily Arundell preferred to spend her peaceful old age with her four-legged friend Bob. She enjoyed good health and certainly did not suffer financially - she inherited a huge fortune. On the contrary, her relatives desperately needed the money, but her aunt was not going to support them in any way. But then the "accident" happened, and a wealthy lady of years conceived a suspicion, which she confided to Hercule Poirot. Her letter caught the detective's attention. He received dozens of similar ones from neurotic unmarried women, but this one caught his eye because it was written on April 17, whereas the post office didn't deliver it until June 28. Therefore, he immediately decided to act and went to the address. But there he finds out that the house is for sale because the owner is dead. How will he get along with the strange Crown witness in the investigation into her supposedly natural death? The novel was the basis for the fourth episode of the sixth television series, in which the famous Belgian detective was portrayed by David Suchet.
