The Women's Royal Naval Service, also known as the Wrens, was the women's branch of the United Kingdom's Royal Navy. Constance Clarke was a member, stationed at Bletchley Park during World War II. She stood up to "John Smith" after he accidentally had one of her Wrens, Sylvia Wimpole, working excessive hours. (AUDIO: Criss-Cross)
Lizbeth Hayhoe was sent ex-Wrens to assist her at Room 13 until Torchwood became aware that she kept seducing them. (AUDIO: Parasite)
