Columbo is a little odd and he asks the man some questions that he finds intrusive. Columbo continues to question him and the man's friend an ADA warns Columbo to watch his step. But Columbo goes on. 可伦坡系列的，第一集试播片。 《神探可伦坡》（英语：Columbo）是一部著名的经典美国电视电影系列，由彼得·福克（Peter Falk）主演。自1968年2月20日～2003年1月30日期间，共播出69集。 本片每集独立成篇，一大特点是每集中客串演出犯人角色的全为名演员与名人。另一特点是剧情采用固定的倒叙推理形式：先描述犯人作案的情形，而后描写可伦坡从与嫌疑犯的交谈及证据中确定其嫌疑，逼得犯人不得不自白。犯人原以为天衣无缝的杀人计划，都逃不过他的锐眼。他的一句名言是：‘世上没有完美犯罪’。 本片特别之处就是使用较少见的倒叙推理形态，着重如何抓住犯人，而不是常见的查证谁是凶手，犯罪手法或动机。这种剧情铺陈手法、以及人物设定，日后受到三谷幸喜所编剧的日剧《古畑任三郎》系列所师法。
