All this time, it will be observed, I had been taking it for granted that the lady in black had followed me from Kensington to this shop; that, in fact, she was none other than Mrs. Schallibaum. And, indeed, the circumstances had rendered the conclusion inevitable. In the very instant when I had perceived the displacement of the left eye, complete recognition had come upon me. When I had stood facing the woman, the brief glance at her face had conveyed to me something dimly reminiscent of which I had been but half conscious and had instantly forgotten. But the sight of that characteristic squint had at once revived and explained it. That the woman was Mrs. Schallibaum I now felt no doubt whatever.
