I'm glad this seems to be such a hit. Personally I think it's tough to rate how smart everyone is, because just about every killer Columbo goes up against seems smarter than I am (except maybe Findlay Crawford).
I'm interested in how the "newer" Columbo killers will stack up against the "older" ones. I'm including a batch of them in my next set.
Keep it up, fellows! I've missed being away from the forum for so long.
