The Herb of Death: A Miss Marple Short Story

Another interesting short story featuring Miss Marple from Dame Agatha Christie. It's about a dinner party which takes a deadly turn when somebody poisons the guests. All of them became seriously ill but one, a young woman, died. The story of this earlier tragedy is related to a gathering of friends at which Miss Marple is present. From the sketchy information, can any of them deduce what happened? Or should we just just look to Miss Marple? Librarian's note: this entry relates to the short story, "The Herb of Death."
