Effie Thursday

Effie was the wife of Edmund. In 1893, she and Edmund entered Sweetville to look for the Eleventh Doctor and Clara. Edmund went inside one of the rooms, warning Effie if he didn't come back in an hour to call the police. Immediately after, Mrs Gillyflower entered, claiming to have come across Effie's "late husband". After saying Edmund was well, Effie heard him scream in the other room. (TV: The Crimson Horror)
