Wow, nice job already...you all are quick! Okay, here are my answers, but I'm afraid there will be a lot more guessing here than mopping...
For #33, I agree with you, Cassa, that Paul Williams says "Leslie, I thought..."
#38 Habib says "I never dreamed I'd be involved in matters of such significance."
#31 is Mark McAndrews in "Make Me a Perfect Murder," asking if they finished showing the film to the bigwigs downstairs.
#34 I thought he said "bye," but I am probably wrong.
#36 This is also a total guess, but is this Jim Ferris assuring his wife that this will be the last time he will stay at the office to work late, since he is finishing the book?
#39 could be Sharon Martin arranging the meeting at 8am at the medical supply company, and Jean in "Requiem for a Falling Star" giving her fake plans for the evening to Nora Chandler when she is given the list of errands?
#32 sounds like Rosanna Wells talking to the poor sappish band guy who gets framed for her murder. I'm not sure which is the real quote, but D sounds the meanest, so it is probably that one.
I'm going crazy over the "yes...yes...yes" one (it sounds a little naughty).
And as far as the end of this.....I am sure Headache is in his cave..and he is contriving another puzzle for us.......
Hey Headache...if you aren't...it's ok...you must be exhausted from all of this....you put in a lot of work....but we Columboites appreciate all that you do. Me and laura are your groupies!!!!!!!!!!!!
