My favorite Columbo episode is "A Friend in Deed". It's one of the only ones I've seen where Columbo is actually stumped and questions whether maybe he's going after the wrong guy for a while. Villain is suitably intimidating, the scheme is also pretty great.

If you misspell a name too many times the person becomes immune and I -think- the person writing it dies. That may just be if you intentionally misspell it though?
