I don't think it should take a detective here....find it in a bookstore...peruse a few pages here and there....decide if it's what you like or expected.
Oh, and just one more thing...Mrs. Columbo would get it at the library....probably the first in line to reserve it.
That way there is money left for Holy Name Society raffle tickets and free cruises.
Peter had said, in an interview not very long ago, that he had other ideas for the book's title (I don't remember if he said what the other possible title(s) might have been) -- then he added that he had a feeling the publisher would want him to call it "Just One More Thing".
Which is understandable, and believable.
Seems to me the title is a good fit with the book's format, as a series of collected anecdotes and thoughts, one after another without an overall narrative plot. But the marketing purpose is pretty clear, as with the cover-photo of Columbo. Who can blame them.
Obviously the title has a twofold interpretation. One: it was a catch-phrase from his defining role; Two; it really is descriptive of the essence of the book.
I bought a book several years ago by Clayton Moore. It had a lot of things in the book other than The Lone Ranger. Of course it was truly interesting and informative, but he didn't go into feelings and real behind the scenes riveting data. Of course I wasn't on a Lone Ranger website either where I got a lot of info. His info was therefore new to me.
His book was aptly entitled: "I Was That Masked Man". (For those of you who never saw the show...every episode ended with someone asking: "Who was that masked man?"...and someone replying "Why that's the Lone Ranger".
