Watched "Short Fuse" last night and I never realized it was one of those episodes that had a "too much in one day" problem until Anne Francis tells Roddy McDowall that she lied about where she was "last night", which means Columbo has been all the way out to the mountain, up the tram and back to the plant AND heard back the report that points to the explosive inside the card and has now formed his theory about the cigar box AND gets back to the mountain before it's dark. Not likely! I really think these kinds of flaws should have been covered by the script editor better to just change "last night" to "the other day" or something like that.
