When a former student turns up in David Mapstone’s office, she seems to have the perfect case for this history-professor-turned-deputy: a letter left by her deceased father, confessing to a forty-year-old murder and providing directions to the body.

The reunion with Robin rekindles memories about their rough upbringing and the deep rift that they may, or may not, bridge. Why is Robin here now?
