Thank you for your comments. I appreciate
DirQ, yes I think you are right about Dr. Flemming coming back home, he saw all the suspicious circumstances and he didn't even say a word.
About Tommy I was thinking that it was a set up made by Columbo but I wanted to hear another opinions.
Fred, thank you for your nice words, and yes, I remember you doing the same thing here, episode by episode, I always had a great pleasure to read it and enjoy :)

NOW YOU SEE HIM had a delayed entrance of 30 or so minutes.
All those lame magic tricks really padded the otherwise good episode.

I also really liked the "extra luggage weight" clue, and I thought it was one of the better clues in the entire series.

The "medical journals" answer was very quick and clever, and definitely proved that Dr. Fleming was going to be a very intelligent and difficult opponent.

And yes as you stated, the"Tell me, those trade journals and those medical books, did you take them with you when you went fishing?" line is absolutely hilarious!
