“Well, Mr. Holmes, you would hardly say it was a face at all. That’s how it looked. Our milkman got a glimpse of her once peeping out of the upper window, and he dropped his tin and the milk all over the front garden. That is the kind of face it is. When I saw her⁠—I happened on her unawares⁠—she covered up quick, and then she said, ‘Now, Mrs. Merrilow, you know at last why it is that I never raise my veil.’ ”

“Do you know anything about her history?”

“Nothing at all.”

“Did she give references when she came?”

“No, sir, but she gave hard cash, and plenty of it. A quarter’s rent right down on the table in advance and no arguing about terms. In these times a poor woman like me can’t afford to turn down a chance like that.”

“Did she give any reason for choosing your house?”
