Today sees the launch of a new social media campaign for PanMacmillan crime author M.R. Hall.

The theme of the campaign is Seven Secrets of Successful Crime Writing – and aspiring Agatha Christies and wannabe Ruth Rendells will have much to learn from a writer who has been nominated twice for the prestigious Crime Writers’ Association Gold Dagger for best novel of the year, and who is also a BAFTA-nominated screen-writer and producer, having written more than forty hours of prime time drama for BBC 1 and ITV.

Facebook users only have to ‘Like’ the Facebook page to reach exclusive video content that could put them on course to creating their own crime masterpiece – and at the end of the campaign there’s an incredible competition too. Bookswarm designed and built the app, as well as producing the videos, and is working with PanMacmillan on promoting the campaign through social media.
