My naughty little sister is the naughtiest little girl in the world, and there's double trouble with her best friend, Bad Harry! There's a peculiar pile of green mouldy crusts on the floor - where has it come from? Bad Harry gets covered in polish and sawdust, but he doesn't think that's naughty at all. And why on earth are those children taking pieces of cheese and bacon rind to the library? Short stories about a loveable, irrepressibly mischievous little girl that small children everywhere are bound to love, read by Jan Francis. Originally written for the BBC's "Listen With Mother" radio programme, these stories were based on Dorothy's recollections of her own childhood with her naughty little sister, and they have enchanted children throughout the world for over fifty years. Perfect for bedtime reading, the stories deal with first experiences and childhood emotions with a huge sense of fun and humour.
