Sylvia Keene

In the short story The Herb of Death, Sylvia Keene was the ward of Sir Ambrose Bercy. She lived with her guardian at his estate Clodderham Court and was engaged to a neighbour Jerry Lorimer. During a houseparty at Clodderham Court, everyone fell ill after eating foxglove leaves mixed with sage in the stuffing of a duck. However, shortly thereafter, Sylvia died, the only one to do so.

Solving the mystery of her death became a challenge set by Dolly Bantry to the Tuesday Night Club.
