The detective’s face was as dull and unimpassioned as a caricature carved out of wood. He stood pointing the pistol with a listless air, and his eyes were heavy and sluggish, as if he were not fully awake. He lowered the weapon almost as soon as he saw the Phantom’s face, but did not put it out of sight.
