I dig into some of the scaaariest novels of all time (according to the internet!) and they all turn out to be pretty cut and dry with their endings! Made it easy, but short!

Novels used: "Rebecca" by Daphne Du Maurier, "Those Across the River" by Christopher Buehlman, and "The Hot Zone" by Richard Preston.
