Miss Block did not appear daunted by the abrupt answer she had received. On the contrary, she gave a curious smile when Madge declined to tell her name, and nodded her head, repeating softly to herself, "I thought so. Just as I thought."

"What did you think?" said Madge at last, feeling intolerably irritated at her customer's mysterious words and manners.

"Well, it wouldn't require a very clever person to guess what you are!" replied Miss Block triumphantly. She spoke as if she had just made some great discovery that gave her infinite pleasure.

"You don't really know who I am, do you?" said Madge with considerable anxiety.

"Well, I am generally considered as sharp as my neighbours, I believe!" retorted Miss Block. "And I can make a pretty good guess! When I find somebody in a shop who doesn't know where any of the things are kept, although I see her pulling them all about as I come in; and when she gets very frightened, and won't tell her name or how she got there, I call that person a thief!"

"A thief! You think I am a thief!" cried Madge, almost more astonished than offended by such an extraordinary accusation. "Why, Mrs. Winter herself told me to stay in the shop while she went off to find the man who—"

"Oh yes! A very fine story. I have heard of that kind of excuse before!" interrupted Miss Block mockingly. "It's my belief you just slipped in when poor old Mrs. Winter was out of the way for a minute, and if I hadn't luckily caught you in the very act you would have been off with your pockets crammed—"

"How can you say such things!" cried Madge. "Why, I have money to pay for everything I want, only it's dropped down the grating into the cellar of the next house, as I was just going to tell you. And while Mrs. Winter went to get the key I was making up my mind what I would buy presently. And as I have five shillings and sevenpence to spend (it's not all mine exactly, but nearly the same thing), you certainly need not say that I wasn't going to pay!"

"Now that's a very interesting story! So interesting that I'll give you the chance of repeating it to a policeman, and we'll see what he says to it," remarked Miss Block, at the same time moving towards the street door as if to go out.

Madge could hardly believe her ears. A policeman being called to examine her just as if she were really a thief! It seemed impossible, but Miss Block, with a most unpleasant smile, was actually turning the door-handle, when she was suddenly seized round the waist by two strong arms.
