Sergeant Frederic Wilson:  J'ever see one of these before , Lieutenant ?
Columbo: Uh ... no , not sure I have . It , eh , looks kind of familiar , though .
Sergeant Frederic Wilson: It 's a camera - mounted starlight scope . They used 'em quite a bit at Berkeley for night work .
Columbo: You mean that takes pictures in the dark ?
Sergeant Frederic Wilson: Yeah . I bought this _ one _ myself .
Columbo: You used your own money ?
Sergeant Frederic Wilson: Well , I wanted to have the best equipment for the job , sir .
Columbo: You must be a bachelor .
