该剧描写了四位武艺、兵器均各具特色，而性格也各有独突的“四大名捕”，追录刺杀皇帝的凶手集团的故事。然而追查的结果，连四大名捕本身也始料不及，所遇到的阻力危险，竟然并非来自凶手集团，而是名捕所意想不到的力量。 全剧过程，峰回路转，揭发了许多令人意想不到的情景，构成一幕连一幕的高潮，他们的矛盾冲突也形成了叠起的激情。
Season 5 finds Murder, She Wrote's intrepid Jessica Fletcher in fine sleuthing form, and venturing farther afield from Cabot Cove--a good thing, since at the rate the murders have been happening, that town would be nearly cleaned out. Some of the best episodes take place in more exotic locales like New York (dead man on the street, wearing just one shoe), Montana (a publishing convention gone horribly wrong) and West Virginia (two whistle-blowers at a coal company found gruesomely murdered). Angela Lansbury sparkles with determination and bonhomie, hitting her stride and then some. Jessica's own life backstory is even filled out tantalizingly, especially in the episode "The Last Flight of the Dixie Damsel," in which an investigation is launched into a mysterious cargo plane that is linked, she learns to her horror, to her late husband. The series' other delight is watching for cameos by stars of a certain age, and this season doesn't disappoint, with appearances by Roddy McDowall, Shelley Fabares, and Dinah Shore--but also some up-and-comers like Megan Mullally (proof positive that the Will & Grace whine was a put-on) and future satirist Bill Maher.
