Love and Mr. Lewisham by H.G. Wells

Lewisham was not quite clear what course he meant to take in the high enterprise of foiling Lagune, and indeed he was anything but clear about the entire situation. His logical processes, his emotions and his imagination seemed playing some sort of snatching game with his will. Enormous things hung imminent, but it worked out to this, that he walked home with Ethel night after night for -- to be exact -- seven-and-sixty nights. Every week night through November and December, save once, when he had to go into the far East to buy himself an overcoat, he was waiting to walk with her home. A curious, inconclusive affair, that walk, to which he came nightly full of vague longings, and which ended invariably under an odd shadow of disappointment. It began outside Lagune's most punctually at five, and ended -- mysteriously -- at the corner of a side road in Clapham, a road of little yellow houses with sunk basements and tawdry decorations of stone.

Up that road she vanished night after night, into a grey mist and the shadow beyond a feeble yellow gas-lamp, and he would watch her vanish, and then sigh and turn back towards his lodgings.
