Jean Morris

 was the wife of Frank Morris. They lived in High Wycombe. One day they were invited to a buffet party at the Fordyce home. They were intrigued because the Fordyces usually kept to themselves.

At the Fordyce home, they learned they were meant to be the buffet for two abnormally large spiders. Some of the guests, including Jean, were encased in webs for later eating. Jean was rescued by the Fourth Doctor. (PROSE: Return of the Spiders)
