So I finally got enough evidence to escape from Innsmouth with the "good" ending.

Father Mateo, Preston Fairmont, Kate Winthrop and Ashcan Pete went in....only Father Mateo and Preston Fairmont came out.

Given that Preston's insane condition wasn't met (he had to clear all of the search tokens and there was literally no way left to do that by the time he went insane), that means that Father Mateo staying alive is the only reason I could still claim victory. I am surprised actually at how useful Father Mateo's skill was, by making sure he almost always used one of his actions to make another investigator focused it kept us out of a lot of desperate scrapes.

Unfortunately, escape was only achieved at the cost of a gifted scientist getting burned alive just as she was about to step onto the boat and Ashcan Pete getting ripped apart by an angry mob in order to buy everyone else time...which I guess means I also know what happened to Duke ....I'm not crying, you're crying!
