Morse finds himself the subject of a murder investigation when his friend, Beryl Newsome, is murdered at a rehearsal of the Magic Flute and he foolishly touches the murder weapon. Morse is suspended and DCI Bottomley, with DS Lewis assisting him, is put in charge of the case. Morse feels that he was set-up and looks to his past to see who, among the many criminals he arrested, might now be setting about seeking revenge. When someone scratches masonic symbols all over his car and he is reported for erratic driving, Morse wonders if Masons may somehow be involved. When a large number of his personal items are found in Beryl's apartment, Morse is placed under arrest
1、4季换了3个验尸官，这个职业留存率这么低么，还是用流动人员背景凸显老Morse与小Lewis的情比金坚？
2、本季美女指数比上一季明显下跌，E02的秘书黑美人Gail不错，黑人要是五官端正起来是真挺漂亮的；
3、按照历史惯例，主角总要被陷害、被嫌疑一回、再排除万难自证清白，老Morse终于等到这一天，就在E4；难得的是最后Lewis总算露了一小脸儿。
青涩明星：喜见30出头的Alex Jennings，还和妈妈一起住，没事在家玩儿火车模型，这时候已经显露出了超出常人的“变态潜质”，眼神儿足够阴森、狠毒了。
地狱对话剧本：
凶（Jennings哦）对老摩（阴森、狠毒眼神）：等我出来就杀你！
老摩--沉默，凝视；
小刘：没事儿老摩，等他出来你早死了！
老摩（恶狠狠）：刘儿啊，你这说话水平不去外交部可惜了。
小刘--背后偷乐。。。。。。
