Beatrice Henniker

In the novel The Body in the Library, Beatrice Henniker is a Girl Guide and a friend of Pamela Reeves. Beatrice and the other friends of Pamela, Florence Small, Jessie Davis, Mary Price and Lilian Ridgeway were all questioned by the police about Pamela's behaviour on the the day of her disappearance. All the girls said the same thing: that Pamela had told them that she was going to Woolworths to do some shopping after the Girl Guides rally and she would go home by a later bus.
