Meanwhile I was watching the old creature with much interest. She had not a common face or a common manner. She was gray, she was toothless, she was haggard, and she was bent, but she was not ordinary or just one of the crowd of old women to be seen on country doorsteps. There was force in her aged movements and a strong individuality in the glances she shot at us as she backed slowly out of the roadway.

"Do they say she is imbecile?" I asked. "She looks far from foolish to me."

"Hearken a bit," said he. "Don't you see she is muttering? She talks to herself all the time." And in fact her lips were moving.

"I cannot hear her," I said. "Make her come nearer. Somehow the old creature interests me."

He at once beckoned to the crone; but he might as well have beckoned to the tree against which she had pushed herself. She neither answered him nor gave any indication that she understood the gesture he had made. Yet her eyes never moved from our faces.

"Well, well," said I, "she seems dull as well as deaf. You had better drive on." But before he could give the necessary jerk of the reins, I caught sight of some pennyroyal growing about the front of the cottage a few steps beyond, and, pointing to it with some eagerness, I cried: "If there isn't some of the very herb I want to take home with me! Do you think she would give me a handful of it if I paid her?"

With an obliging grunt he again pulled up. "If you can make her understand," said he.

I thought it worth the effort. Though Mr. Gryce had been at pains to tell me there was no harm in this woman and that I need not even consider her in any inquiries I might be called upon to make, I remembered that Mr. Gryce had sometimes made mistakes in just such matters as these, and that Amelia Butterworth had then felt herself called upon to set him right. If that could happen once, why not twice? At all events, I was not going to lose the least chance of making the acquaintance of the people living in this lane. Had he not himself said that only in this way could we hope to come upon the clue that had eluded all open efforts to find it?

Knowing that the sight of money is the strongest appeal that can be made to one living in such abject poverty as this woman, making the blind to see and the deaf to hear, I drew out my purse and held up before her a piece of silver. She bounded as if she had been shot, and when I held it toward her came greedily forward and stood close beside the wheels looking up.

"For you," I indicated, after making a motion toward the plant which had attracted my attention.
