Ingrid (Cat Among the Pigeons)

In the novel Cat Among the Pigeons, Ingrid is a Swedish princess, attending Meadowbank School for Girls.

Margaret Gore-West, the head prefect describes Ingrid as a princess who is "rather fun", with very blue eyes but wears braces. That she is Swedish is inferred from Julia Upjohn who told her mother that there is "a jolly Swede" and that she's "a princess or something". Presumably she is referring to the same person as Margaret Gore-West.
