Gibraltar School was founded as a school for young ladies by the two dear old Misses Pye, now deceased.  The long-suffering teachers now have their lives made miserable not only by their pupils but also by the present headmistress, Miss Rowe, known universally as "Hard Rowe".  Since Gibraltar is a private school, they resign themselves to the fact that there is little they can do about it, but they find help coming from a very unexpected quarter indeed.
