Hint 1: Yes, this is in fact a puzzle. Hint 2: The last paragraph tells you how to solve. "Those mixed-up puzzle authors removing character..." Hint 3: The Table of Contents is part of the puzzle. Focus on the all-caps last names. Hint 4: (directions on how to solve) Each name can be found anagrammed, with one letter added, and possibly split into multiple words. The first few are "wisest" = WEISS + T, and "a noble" is LEBAN + O.

The Solution: The extra letters once all the names are found, taken in the order they appear in the letter, spell out the message "to reveal my true name you'd spoonerise me".
