I agree about Requiem and Forgotten Lady. I have a similar issue with Double Exposure, which always makes me think of the Negative Reaction episode. Ironically, Negative Reaction is one of the best titles in the entire series, but that doesn't stop my brain from taking a wrong turn.
"Murder By The Book" is an appropriate title for the episode. Ken Franklin actually uses his own idea in the Mrs. Melville books to kill Ken Franklin. However, Columbo mentions that the way he killed Lilly La Sanka was sloppy and "Mrs. Melville would be disappointed."
Apple TV has, I believe, the first seven seasons of Columbo. Unedited. I am sure it is the first five seasons. It's nice to have him back.
So many times over the years Bye Bye Sky High IQ Murder has made me think of Roddy McDowell in the cable car with the cigars over the floor rather than the actual episode. Also I find it difficult to remember which Jack Cassidy author episode is which.
