sabra, that was Mary Wickes playing Tracy O'Connor's landlady.
Isn't that scene hysterical!!! I really love it. How she admonishes Columbo for bothering her bird Walter...and when they are going through the photo album and she has to make a comment on every relative that is in the pictures.............Columbo got a dose of his own medicine!!

That is a priceless scene because it shows Columbo on the receiving end of what he puts so many people through.

Exactly! She was definitely a true match for him!!
