Solving Approach
This one works out to about 5.2 letters per word on average. This puzzle leans toward longer words — apostrophes and doubled letters will likely crack it open faster than word length alone. This is rated hard — the substitution pattern is less forgiving, so patience with frequency analysis pays off.
