Captain Did It

The secret "blame the captain" bad ending. Progress far enough to have viewed every accessible memory, then attribute every death to Captain Robert Witterel - assign a homicidal cause ("axed" is simplest) to each soul, and set the captain himself as suicide; correct names aren't needed. The two souls only revealed in Chapter VIII (Perrott and Dahl) stay unassigned. Board the rowboat when the boatman warns of the coming storm. Do this on a separate save so you don't corrupt an honest solve.
