Thanks for the guidance, Kevin.

I wonder: could the same technique be applied to other texts?  For example,
consider the phrase, "Kevin 's helpful response."  If we take the ten
letters after the apostrophe in that phrase, we get "shelpfulre".  Reading
them backwards we get "erlufplehs".  Ignoring such almost-words as "er" and
"luf," we find just one word: "eh."  Now what can that mean?  Of course,
we'd need many pages of text to get the whole secret message, but at least
it's a start.
