This fourth series of the detective drama impressed many critics this year with actress Brenda Blethyn playing a blinder as DCI Vera Stanhope. In this final episode of the series. The detective investigates the mysterious death of businessman John Shearwood, found floating in the water under the Gateshead Millennium Bridge when he was supposed to be on a golfing trip to Ireland (well, here, maybe we should say). Turns out he was working as an informant for HM Revenue and Customs, but why spy on your own firm? Vera will be on the case! Along with her trusty sidekick Joe of course.
