This is fun Leighton!

Since you just posted this I will only take one of them.
um.....#2 sounds a trifle familiar.....hmmm.......let's see.........could it be from Etude in Black????

One down...three to go! It's past 10.00 in the UK, I'm sure that the brains of you people in the US will be functioning better!

Ok...I can't resist...I'll do one more.
#4 is from Short Fuse. It is when Aunt Doris and Roger and Columbo are standing at the bar, and she says she called the Comissioner and he had promised to send over "his best man." (I love the way Roddy smiles when Peter delivers this line! )

Ok...I will not be a Quiz Hog...so I will go away now.

Thank you, Cassavetes, for not being a Quiz Hog! (And that's a cute expression!)

#3 is from Suitable for Framing.

#1 is from "A Matter of Honor"

And as already mentioned, #2, #3, and #4 are from
"Etude in Black," "Suitable For Framing," and "Short Fuse"

Thanks E...but I stole that expression from someone on here!!

Ok..Mr. Leighton Sir, we are hungry for more....no pressure!!!

I'm very impressed...and descriptions as to what part of the episode it was said.

I'm just going to have to start making things a wee bit more difficult. I'm on the case...
