Amelia Birch
From Tardis Wiki, the free Doctor Who reference
Miss Amelia Birch was the owner of Devastation Hall in the Silver Devastation where she ran the Game of Death.
While she appeared to be a mature woman with sharp, thin features, hard, little eyes, grey, sharp teeth and purple glasses that enabled her to scan guests, she was a Nocturn in disguise.
When the Game of Death ended, this criminal Nocturn awaited arrest and transport by the Judoon. (PROSE: The Game of Death)
