Wrykyn in The Gold Bat; in Jackson's Extra, he regards his house as a warder
might a gang of convicts. Fives is his one relaxation. He is
O'Hara's house master in Jackson's Extra and The Deserter. G. Montgomery
Chappie's form-master in The Politeness of Princes, still a house-master in The White Feather.
