My mother and sister had spoken so many last words, and had begged me to wait another five minutes so many times, that it was nearly midnight when the servant locked the garden-gate behind me. I walked forward a few paces on the shortest way back to London, then stopped and hesitated.

The moon was full and broad in the dark blue starless sky, and the broken ground of the heath looked wild enough in the mysterious light to be hundreds of miles away from the great city that lay beneath it. The idea of descending any sooner than I could help into the heat and gloom of London repelled me. The prospect of going to bed in my airless chambers, and the prospect of gradual suffocation, seemed, in my present restless frame of mind and body, to be one and the same thing. I determined to stroll home in the purer air by the most roundabout way I could take; to follow the white winding paths across the lonely heath; and to approach London through its most open suburb by striking into the Finchley Road, and so getting back, in the cool of the new morning, by the western side of the Regent’s Park.
