Jean, along with her friend Phyllis, was an evacuee from London who lived with Miss Hardaker. On a Sunday in April 1943, she met Ace and the three girls went to Maiden's Bay together, against Miss Hardaker's restrictions. She later got in trouble with Miss Hardaker for going there. Jean and Phyllis later went back to Maiden's Bay and were converted into Haemovores to serve Fenric.

She and Phyllis returned to Miss Hardaker's cottage and drained her of blood, killing her in the process. She later marched with the Haemovores. She was killed when Fenric asked the Ancient One to kill all the remaining Haemovores, rotting and melting away into a slimy substance. (TV: The Curse of Fenric)
