Twin Mystery

America's most famous detective receives a letter predicting his own failure. A murder will occur, Nick Carter knows not where or when, but the Brown Robin has promised it. The taunt comes from a phantom who understands the detective's methods as well as he does. Carter's wife Edith suspects the writer is a woman, but the clues point everywhere and nowhere. As the famous detective investigates, the mystery deepens into something far more personal: an adversary who has studied not just crime, but Carter himself. What begins as a straightforward case becomes a battle of wits between two minds, one seeking justice, the other seeking humiliation. The Brown Robin knows exactly how Carter thinks, and that knowledge is terrifying. For fans of early detective fiction, this is a compact, satisfying puzzle box of a story, procedural intrigue wrapped in turn-of-the-century American grit.
