I've seen this episode so many times but I discovered something new when Colombo goes over to See Carsini's secretary Karen at her house he knocks on the door and she is watching an Allen lad Western… ( this gun for higher ) If you notice on the table where she's sitting there's a bottle of obviously cheap wine because it has a screw top on it… Probably a bottle of mouthwash from the Marino Brothers… You would think that Carsini would at least let her have some wine at wholesale… She's obviously not a connoisseur at all.
