Norman Gortsby sat on a bench in the Park, with his back to a strip of bush-planted sward, fenced by the park railings, and the Row fronting him across a wide stretch of carriage drive. Hyde Park Corner, with its rattle and hoot of traffic, lay immediately to his right. It was some thirty minutes past six on an early March evening, and dusk had fallen heavily over the scene, dusk mitigated by some faint moonlight and many street lamps. There was a wide emptiness over road and sidewalk, and yet there were many unconsidered figures moving silently through the half-light, or dotted unobtrusively on bench and chair, scarcely to be distinguished from the shadowed gloom in which they sat.
