New BBC series to sink your teeth into tonight. It's yet another crime drama but sure we can't get enough of those these days. The four-part series is adapted by Bafta-winning writer Danny Brocklehurst (Ordinary Lies, The Driver) from Mark Billingham's best-selling books. 'In the Dark' stars Ripper Street's MyAnna Buring as Helen Weeks, a pregnant detective who must return to her hometown when two girls have been abducted. The man who has been arrested is the husband of Helen's childhood best friend Linda Bates, who has found herself drawn into the centre of a media storm, while the local police force is under enormous pressure to get their man... but is he guilty?
