Nurse Maclean was one of the medical staff who looked after Elsie Howard when she was hospitalised in 1973. Elsie had caught a train to London to visit her son Dennis. After returning to retrieve her handbag which she had left on a park bench, Elsie was knocked down by a taxi. She suffered a frontal fracture of the skull and severe concussion. Maclean and Sister Delaney enjoyed speculating about the identity of "sleeping beauty", who had been found without any form of identification.
Though still unconscious, Elsie herself provided the key to establishing her identity by muttering to herself in her sleep in the vicinity of Nurse Maclean. Maclean passed onto Sister Delaney three phrases Elsie had repeated - "double glazing", "Pentonville", and "Dennis Tanner", along with her estimation (from her accent) that Elsie was from the north. Delaney gave this information to WPC Tomlin, who was then able to identify Elsie.
