Ambrose Bercy

In the short story The Herb of Death, Sir Ambrose Bercy was the father of Martin Bercy and the guardian of Sylvia Keene. He resided at Clodderham Court and was also a friend of Colonel and Mrs Bantry who were his guests at the time of the story. During the houseparty in the story, all the guests fell ill after foxglove had been mixed with sage in the stuffing of a duck. Shortly thereafter, his ward Sylvia died. Dolly Bantry described Sir Ambrose as a elderly and courtly gentlemen.

After discerning the truth behind Sylvia's death, Miss Marple likened Sir Ambrose to one of her village parallels, Mr Badger.
