回复 :人心，是一门深奥的科学。人会犯罪作恶，皆因被贪婪、愤怒、软弱和嫉妒等情绪支配。为了逃避刑责，人会利用谎言掩饰真相，用诡计扰乱视线，令法证工作难上加难。未破的悬案、消失的证据、迷失的困局，都是法证团队面对的一个个难关。纵然过程中会受到打击，但他们都会坚持初心，跌倒之后重新出发，不会放弃追寻真相。《法证先锋V》的案件和布局更加让人意想不到，唯有靠着“法证部”、“法医科”及“重案组”这灭罪铁三角，秉承前四季的理念，通力合作，找出真凶，还生者公道，替死者雪冤。

回复 :Deputy Assistant Commissioner Charlie Hillian is killed on the night of his retirement party. Hillian was at one time a senior officer in Oxford and was in fact Morse's boss. He was also writing a book about his most memorable cases, including one about the unsolved death of an 8-year-old girl some 18 years ago. The suspect in that case, Frederick Redpath, was at Hillian's house the day he died and that chapter from the manuscript is missing. There are other suspects however, including Hillian's ghost writer who will now receive all of the book's royalties; a handyman who was working on the property; and Redpath's daughter, who knew the little girl who was killed all those years before. Morse comes into conflict with with a colleague DCI Dawson, who was one of Hillian's protégés, as they again look into the little girl's death.
