Emily Pringle was a patient at the Greyson Institute. She was an accomplished violinist but her abilities did not manifest themselves until after an accident where her head was struck. She was under the care and study of Dr. Francis Grout.
Pringle saved the lives of Detective William Murdoch and Sarah Pensell when they were being attacked by Richard Binney. Binney had shot Murdoch with a crossbow bolt and would have killed him had Pringle not struck Binney unconscious from behind.
