Not all tarts are apple

"Seven year old Rosie lives happily with Uncle Bert and pillow-plump Aunt Maggie above their cafe in Old Compton Street. The Soho neighborhood is rife with tough and sinewy London life including pimps and prostitutes, thieves and con men, the bent and the wicked. One day at school Rosie learns her real mum's a tart." -- Jacket.
