According to Rachel Crawford's
Bonza Schooldays, 'Jancy's schooldays are continued in
Jancy Scores Again, which mostly centres on the mysteries surrounding two new girls at Jancy's school. As with Bracken's previous Jancy title,
Jancy Wins Through, the school provides a background for mystery and adventure plots. The two new girls who arouse interest at the school are Giralda Channing, a glamorous American teenager, and twelve-year-old Brigid O'Brien, a pianist prodigy. Giralda rouses Jancy's interest when she appears to go into hysterics when Brigid is playing, while Brigid and her Nurse seem to be hiding from someone.'
