'Superseded' is an adventure novel written by May Sinclair. The story, set in a school, unfolds by introducing us to Miss Quincey, which the author describes as "...a little dry, brown woman, with a soft pinched mouth, and a dejected nose. So small and insignificant was she that she might have crept along for ever unnoticed but for her punctuality in obstruction. As St. Sidwell's prided itself on the brilliance and efficiency of its staff, the wonder was how Miss Quincey came to be there, but there she had been for five-and-twenty years. She seemed to have stiffened into her place. Five-and-twenty years ago she had been an arithmetic teacher, vaguely attached to the Second Division, and she was still an arithmetic teacher still. Miss Quincey was going on for fifty; she had out-lived the old Head, and now she was the oldest teacher there, twice as old as Miss Vivian, the new Classical Mistress, older, far older than Miss Cursiter. She had found her way into St. Sidwell's, not because she was brilliant or efficient, but because her younger sister Louisa already held an important post there."
