Do you think that Hasan Sallah from Case of Immunity made a perfect murder?Columbo just couldn't catch him anyway except on his own confession.That means he didn't leave any traces while he was commiting a crime?

A perfect murder?

Columbo also needds a confession in "It's All In The Game"

i rather loved this episode...i never saw it all that often on tv and i just loved the seething impatience of hassan sallah towards Columbo!!! this is where you see columbo like water...just keeps wearing away at the rock....i think this was a perfectmurder except for sallah's arrogance and impatience which done him in...and columbo always gets his man
