Maud Prentiss was an elderly passenger on Elsie Howard's train from Piccadilly Station to London Euston in July 1973. Elsie was on her way to visit Dennis at Pentonville Prison after he'd been banged up for running a double glazing scam. Out of shame, she'd told Alan that she was going to see her friend Sheila Crossley in Sheffield. Credited as "Mrs. Maud Prentiss".
