Dumb Witness // Poirot Loses a Client — Agatha Christie

At first Hercule Poirot found Miss Emily's letter quite typical--a dramatic, somewhat hysterical appeal for confidential assistance. What piqued Poirot's interest was that it was dated two months prior. Who would wait so long to postmark a life-and-death plea? A visit to Miss emily's estate reveals that the wealthy mistress of Littlegreen had been dead for some time, leaving behind a bitterly contested will, and a pack of greedy heirs with motives for murder. What Poirot really wants to know is who mailed the letter? And why so late?
