The doctor appears in Winter Holiday and The Picts and the Martyrs. He is described (WH8) as a small, neat, pink-faced man, with a bowler hat and white chamois leather gloves. He drives a car, which has a running-board; and he says that "The car's meant to hold four, so there ought to be room for a mere eight”. As the doctor and Dorothea are in the front there are six in the back.
In The Picts and the Martyrs he agrees to not tell the Great Aunt about the Ds unless asked. The Great Aunt is not sick but likes to have a doctor hanging about like she has at Harrogate. Nancy says He’s never as bad as he pretends. (PM8). In the final scene, he stammers to the Great Aunt that he thought he might have been needed (PM29).
