Mafia 90. The Tale of Oldforest.

The clue is actually bad. G.K. was right.

It should have a feedback loop. That is, the GM, looking at the player's profile/quest, can ultimately come to the conclusion indicated in the clue.

That's why I doubted my clue. It didn't quite lead smoothly from his profile to Trianon. It's even worse with Mika.

I figured out how to get from Mika to Trianon.
