In 1949, Jessica Thomson requested that police not keep a permanent record of her name or release her details to third parties, as it would be embarrassing and harmful to her reputation to be linked to such a case. The police agreed – a decision that hampered later investigations. In news media, books and other discussions of the case, Thomson was frequently referred to by various pseudonyms, including the nickname "Jestyn" and names such as "Teresa Johnson née Powell". Gerry Feltus (2010) claimed he was given permission by Thomson's family to disclose her names and that of her husband, Prosper Thomson. Nevertheless, the names Feltus used in his book were pseudonyms. Feltus also stated that her family did not know of her connection with the case, and he agreed not to disclose her identity or anything that might reveal it. Thomson's real name was considered important as the possibility exists that it may be the decryption key for the purported code.
