Other mistake: Columbo never told the character Graham McVeigh that he was sick from clams. When Columbo came to the horse track to talk to him about the case, McVeigh said to Columbo "not more clams?" when Columbo said he was sick again.
Other mistake: Kingsley doesn't know if his victim is married or unmarried, whether or not he has children, if he has a maid, but he brings a hand vacuum and empty vial to the murder to collect cat hair from the victim's cat to plant on Clifford's jacket.
Murder with Too Many Notes - S13-E4
Other mistake: In the movie within the story the murderer repeatedly stabs the victim and pulls back the knife. Even after several stabs there is no blood on the knife. (00:02:25 - 00:05:45)
