I was not able to nail down all of them. Hopefully most......

#31 "Finished already?" is from "Make Me a Perfect Murder," said by Mark McAndrews.

#32 "Troubled Waters." I believe the answer is D

#33 "Leslie, I thought" is correct, that is if you do not count Paul Williams' voice on the tape recording for the phone call after his death.

#34 Darling (D)

#35 "Yes, Yes, Yes" gave me the most trouble.
My guess is "Requiem For a Falling Star."

#36 "Murder By the Book"

#37 C "After you, sir."

#38 B

#39 As for the "exact time of day" question, Ruth
Litton's brother in "Old Fashioned Murder" is probably one of them. I do not know the other.

#40 B

Hmm. The last thing Edward Lytton ever did was record the museum inventory on tape. I don't THINK he mentioned the time, but I may be wrong.

Aha, I think I got #35! Nadia Donner, in "A Deadly State of Mind," responding to Collier's post-hypnotic suggestions!

(And I'm kinda sad, because Headache is gonna run out of victims soon! Hopefully he'll think of a series equally good!)

I think you may be right on that one Leaper!!

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!!!!!!!!!!!!

What Cassa said!!

Btw, we're still working on the groupie tee shirt slogan. Something along the lines of..."My head LOVES the headaches Headache's puzzles give!"

or "Columbo Headaches Rule!"

...or somethin' like that.

Nadia Donner...You got it, Leaper!!! This one was driving me crazy!

Excellent!!!!

I have posted the answers to #31 - 40 in another post! Be there! Or be... somewhere else. Whatever.

..............or be square.....boy! I am showing my age!
