The Master Executioner — Loren D. Estleman

Ordinary people do not understand Oscar Stone. Everything he does, he does impeccably. He is a profound student of his art, completely versed in its traditions over the centuries. He is a student of ropes and their properties, a master of the latest scientific knowledge about the human neck, a careful calculator of weights and drops, and an exacting observer of results.

For more than a quarter of a century he has worked to create a reputation as a man peerless in his craft: the master executioner.

Yet he is utterly alone: His devotion to his work costs him his marriage. Suddenly, one day, a piece of his past catches him unawares, and Oscar comes to a moment of devastating truth and for the first time knows himself.
