在这部贵族侦探剧情/喜剧/悬疑片中,《贵族侦探》是富士电视台2017年春季月九档播出的推理剧，由中江功、金井纮、相泽秀幸导演，黑岩勉编剧，相叶雅纪主演，于2017年4月17日首播。
该剧改编自麻耶雄嵩的推理小说《贵族侦探》及其续作《贵族侦探对女侦探》，讲述了年龄、身世、住所、本名都完全是谜的青年号称“贵族侦探”，却对推理这种“杂事”毫无兴趣，让身边的女佣、司机和管家代替自己推理破案的故事。
相叶雅纪饰演年龄、家庭、学历、住所、甚至连名字都成谜、自封“贵族侦探”的青年，武井咲饰新人侦探，井川遥饰被她视为师傅的侦探，生濑胜久饰刑警，中山美穗饰女仆，泷藤贤一饰司机，松重丰饰执事，仲间由纪惠饰谜之人物。
A man identifies himself as "Kizoku" ("Aristocrat") and works as a private detective for a hobby. Nobody knows his age, address or anything about his family. The actual deductions and investigations are carried out by his employees including his butler, maid, and chauffeur. He only has a good time talking to the women involved in the cases. Meanwhile, Takatoku Aika works as a private detective. She competes with the Aristocrat Detective to solve cases.
贵族侦探渐入佳境 果然没有令人失望。演员跟脚本的竞相尴尬。爱拔：这锅我可不背。大腕的盛宴让推理成为配菜。是要邀请我来进行一场吐槽的冒险吗？。扩大只能暴露缺点（第五话更新）。所有的一切都是原著的锅。推理这种杂务交给佣人就好了！。华丽的外表，hold不住的内心。闲时看看挺不错。
