Shirley Homes and the Lithuanian Case – With Audio Level 1 Oxford Bookworms Library [EPUB ebook] 

A level 1 Oxford Bookworms Library graded reader. This version includes an audio book: listen to the story as you read. Written for Learners of English by Jennifer Bassett. Shirley Homes is a private investigator. She is clever with computers, and knows London like the back of her hand. She laughs when people say, 'Was Sherlock Holmes your grandfather?’ Sherlock Holmes, of course, was not a real person, but, like Sherlock, Shirley has good eyes, and good ears. And she knows the right questions to ask. And in the Lithuanian Case, the right questions are important. Because Shirley must find a missing person – Carrie Williams, aged fifteen. Where is she? Who is she with?
