Query: Not the best, not the worst

CONS: The pace is a bit slow, the ending is built around a hackneyed mystery gimmick, and the idea of a "Watson" as a tortured voice inside the detective's head (created by the psychological scars of WWI shell shock) works better in theory than in practice.PROS: I enjoyed the detective, Rutledge, and his overall likeability, and I appreciated the sort of Golden Age feel that underlies the tone of the work (FYI: There is much more character psychology in this novel than you'd get from a 1930s puzzle mystery, which many modern readers will like while others won't).
