Miss Sanderson

In the novel Postern of Fate, Miss Sanderson is a woman attending the White Elephant Sale in Hollowquay. She expressed an interest in a big brass lamp which Tuppence had and was very pleased when Tuppence said she could have it. Tuppence was happy to give it away because she had never liked it. Miss Sanderson offered to come over to collect it but Tuppence said she would bring it to the White Elephant sale.
