Theodore Merrett of Seymour's is one of Wrykyn's least deserving inmates, a notorious outsider in An International Affair. Would-be competitor of Locksley Lines Supplying Trust, Ltd.-which he betrays to Mr. Appleby-and an enemy of Linton's in A Corner in Lines. In A Division of Spoil, aged 16/2, he cheats on a French exam to win a prize so that his father will buy him a banjo.
