Angèle Blanche

Miranda Raison as Angèle Blanche

In the novel Cat Among the Pigeons, Mlle Angèle Blanche was the new French teacher at the Meadowbank School for Girls. Prior to her work at Meadowbank, she lived in southern France, in the surroundings of Bordeaux. The police suspects that Mlle. Blanche found out who killed Miss Springer, and tried to blackmail the murderer. She ended up being bludgeoned with a sand bag.

When the real Angèle Blanche had died, her sister used her testimonials and her passport. With this she posed as Angèle and started working at Meadowbank.
