Laura Lee Hope was a pseudonym used by the Stratemeyer Syndicate. It pioneered the technique of producing long-running, consistent series of books using a team of freelance authors to write standardized novels, which were published under a pen name owned by the company. This book is from The Moving Picture Girls series. Ruth and Alice DeVere and their father struggle to make ends meet while Mr. DeVere seeks another theatrical engagement. A friend suggests that Mr. DeVere come work as an actor in the moving pictures, which Mr. DeVere considers vulgar -- it is only after the family is served an eviction notice that Mr. DeVere gives in and accepts work in the 'movies'. The family's financial situation improves, and in time, Alice and Ruth win positions with the film company, too. The girls have several thrilling adventures and help prevent thieves from stealing a friend’s new invention.
