I don't disagree with you, in principle anyway. I supposed where I begin to disagree is with the notion that Brindlewood Bay is the latter rather than the former, which it plainly isn't (setting aside notions of whether it succeeds at that design task). I
I have not read or played Bindlewood Bay.
However, what has been described to me is - you go about and find clues. You then put together clues to make a theory - when your party has consensus on what theory they are going with, you roll to see if that theory is correct. If it is not, you gather more clues until you can put together a new theory.
That, if accurate, seems very much "telling the story of solving a mystery", in that there is no predetermined puzzle for the players to solve. The mechanics effectively decide whodunnit, without anyone knowing that before play began.
... but given that there are many, many, fans of BBay who think the mechanics work marvelously as a mystery game, and who experience wonderful fulfilling games with it
The number of people who have wonderful games with may indicate if it is a fun game, but it does not determine whether it is "solving a mystery" or "telling the story of solving a mystery," as I defined it above.
