Mystery writer behind best-seller

The series The Promotion Story of Du Lala has been well-received since its debut in September 2007. The story about how Du Lala, the heroine with ordinary background, grew from an administrative assistant to an HR manager in one of the Fortune 500 companies through her own efforts became a bible for office workers.

Three books in the series have been released as of May, with sales of more than three million copies according to the publisher. The movie, TV and play rights for the first book were sold, and the movie, released this April, turned out to be a huge box office winner, taking in more than 100 million yuan.

Despite all the glory, the author, Li Ke, has remained behind the veil. She is known to have graduated from a prestigious university with an undergraduate degree and to have worked in one of the Fortune 500 companies for more than 10 years in sales and human resources. But she never revealed her identity or released any photos and she only receives interviews via e-mail.
