Schwartz (Citadel Press) In 2011, Russ Faria came home from a night of watching “Conan the Barbarian” with friends, to find his wife, Betsy, lying on the floor in a pool of blood. A knife was sticking out of her neck. In a state of panic, Faria called 911 to say he thought his terminally ill wife had committed suicide.
