In "A Trace of Murder," Shera Danese and David Rasche are having an affair and try to get her husband out of the way by framing him for the murder of a business rival. Here's the thing, though- Rasche is the CSI lead on the case! A perfect way to make sure all of the evidence points the wrong way. But whoops- here comes Lt. Columbo with a bag of bananas and a sneaking suspicion that the clues are lining up a little too perfectly. The AV Club's Gwen Ihnat is here to talk about the weird recap at the end of the episode, Dennis Franz nudity, the possibility of a Columbo reboot and oh, so much more.
