Orphan Warble Mildew has successfully managed to get herself expelled from school. She becomes a waitress and learns how to make the best cream pie around, attracting the attention of the wealthy Mr Petticoat. Winning over his heart with her pies, Warble soon becomes Mrs Petticoat and has to learn how to adjust to her new surroundings and position in life, with often hilarious consequences. Carolyn Wells' 'Ptomaine Street' is widely regarded to have been a parody of the hugely successful novel 'Main Street' by Sinclair Lewis, published a year earlier.-
