Pixie O'Shaughnessy was at once the joy and terror of the school. It had been a quiet, well-conducted seminary before her time, or it seemed so, at least, looking back after the arrival of the wild Irish tornado, before whose pranks the mild mischief of the Englishers was as water unto wine. Pixie was entered in the school-lists as "Patricia Monica de Vere O'Shaughnessy," but no one ever addressed her by such a title, not even her home-people, by whom the name was considered at once as a tragedy and a joke of the purest water.
