Watson, could it be that you are mistaken, and therefore making an error?

What kind of error could there be?
The clue is a book about little people.
Kyle's profile mentions the Nibelungs.
This is:
1) People,
2) Little,
3) There is a fairly well-known book written about them.
There simply cannot be an error. I don't believe in such coincidences. Especially when there are no other coincidences.
