An instant’s reflection reminded me that when she had spoken to me a few moments before, both her eyes had looked into mine without the slightest trace of a squint. My thoughts flew back to the lump of sugar, to the unguarded milk-jug and the draught of tea that I had already swallowed; and, hardly knowing what I intended, I started to my feet and turned to confront her. But as I rose, she snatched up her change and darted from the shop. Through the glass door, I saw her spring on to the footboard of a passing hansom and give the driver some direction. I saw the man whip up his horse, and, by the time I reached the door, the cab was moving off swiftly towards Sloane Street.
