"One Soul At A Time," by Dana Cameron, in Ellery Queen's Mystery Magazine, June 2012.
The story begins with her receiving the obituary of her mentor, a former college professor who changed her life forever. She spots a clue in the obituary that the death was not the accident the authorities claimed and goes rushing off to Maine to discover the truth. This turns out to involve some very bad locals with even worse allies. Our nameless character reluctantly finds herself getting deeper and deeper into the mess, first to pay the debt to her mentor and then, when that is done, for "extra credit, bonus points."
The wise heads tell me that suspense stories are personal and thrillers are global. The world is in danger! But to my mind a suspense story is about what we might call a civilian in danger, while a thriller is about a pro. This story is a thriller, and a very good one.
