Muna's bedroom is a dark windowless cellar and her activities are confined to cooking and cleaning. She???s grown used to being maltreated by the Songoli family; to being a slave. She???s never been outside, doesn???t know how to read or write, and cannot speak English. At least that???s what the Songolis believe. But Muna is far cleverer - and her plans more terrifying - than the Songolis, or anyone else, can ever imagine .
