This is a really good Columbo episode. I just watched it after frankly giving up on Columbo for a few years after watching it for decades, but I had never watched this one. It was on Roku Channel with very small commercial breaks, much better then we had to put up with on 1970s broadcast TV! I had been watching some Oskar Werner films (The Last 10 Days, about the Berlin bunker) and wanted to see more. Someone on his bio mentioned this and I'm glad I finally watched it 50 years after it was made. For me this had the best Columbo ending I ever remember, except maybe the one with Donald Pleasence, that one is also very memorable. But Oskar's character really takes the bad police news like you can believe it, not like a person automatically admitting guilt like in a Perry Mason. His acting is top notch at the end! 10 of 10.
