Celia Ryder is Charles Ryder's wife. They have two children. Because of a marital fidelty by Celia and his long trip to the jungles of the Amazon, Charles has become distanced from her and enters into an affair with Sebastian's sister, Julia Flyte, who is engaged to and marries Rex Mottram. Celia is the sister of boorish Boy Mulcaster. She is crisp, clean, perfectly English, and is very conscious of her social standing and deportment. Her relationship with Charles becomes loveless, which often brings her to tears. Jane Asher was perfectly cast in the role for the Granada TV series.Frederic Kahler
