In the novel The Secret of Chimneys, Anthony Cade is an adventurer, who went to school in England. He was described as a man with a "tall lean figure, sun tanned face, and a light-hearted manner with which he settled disputes and cajoled them into good temper". He is a friend of James McGrath, who calls him "Gentleman Joe". It is not explained why, and Cade himself answers in very vague terms when asked by a Miss Taylor.
He had briefly worked as a touristic guide for Castle's in Bulawayo due to financial difficulties. He later travelled to England under the name of McGrath, and stayed at the Jolly Cricketers.
