Bronny, a young Australian, finds herself down and out in London. She's a sheltered girl - gentle and kind - who has spent her teenage years in a fearful bubble. She's never taken drugs, had sex or killed anyone. Within six weeks she's done all three. A group of backpackers break into an abandoned London townhouse seeking a rent-free life of debauchery. They don't realise someone's already there: a terrified woman bound and gagged in the basement. "The Devil's Staircase" combines a chick-lit voice and a dark crime noir environment. Funny, entertaining and disturbing from start to finish.
