Peasegood

In the Miss Marple short story Death by Drowning, a man named Mr Peasegood is mentioned by Miss Marple as another of her "village parallels".

Peasegood was an itinerant seller of vegetables, and probably also a resident of St. Mary Mead. One day he had come round with his cart to sell vegetables to Miss Marple's niece and had left turnips instead of carrots. Miss Marple mentioned Peasegood and this incident as a parallel for why she was certain she knew who had killed Rose Emmott but she had no facts to offer. How this parallel worked was not explained.
