How Rose Tyler solved the Broadchurch murder

Rose Tyler, who never met 'The Doctor' wanted to be a policewoman since she was little. Now she is qualified and sailed through the ranks to become a DS and has been moved to the small coastal town of Broadchurch and is awaiting another promotion to DI but her hopes are dashed when gruff DI Alec Hardy gets her job. The said DI has obviously never met a Tyler woman before.
