'How do you know that?'

'It was one dark night, when it was raining hard—I could hear it drip, drip, drip upon the roof just over where I was lying. It was when I was very bad, and lay still all day and couldn't speak. But I knew what grandmother said to me, and I knew everything that was going on, though I didn't seem to—that was the curious part of it. I had been asleep for a bit, and I woke up all of a sudden, and heard some one talking to grandmother in the next room—the door wasn't wide open, only ajar. I shouldn't have known who it was, for I'm not quick at telling voices, like other folks; but I heard grandmother call her Mrs. Darrell; and I heard the lady say that when one was sick and tired of life, and had no one left to live for, it was best to die; and grandmother laughed, and says yes, there wasn't much to live for, leastways not for such as her. And then they talked a little more; and then by and by Mrs. Darrell asked her for some stuff—I didn't hear the name of it, for Mrs. Darrell only whispered it. Grandmother says no, and stuck to it for a good time; but Mrs. Darrell offered her money, and then more and more money. She says it couldn't matter whether she got the stuff from her or from any one else. She could get it easily enough, she says, in any large town. And she didn't know as she should use it, she says. It was more likely than not she never would; but she wanted to have it by her, so as to feel she was able to put an end to her life, if ever it grew burdensome to her. "You'll never use it against any one else?" says grandmother; and Mrs. Darrell says who was there she could use it against, and what harm need she wish to anybody; she was rich enough, and had nothing to gain from anybody's death. So at last, after a deal of talk, grandmother gave her the stuff; and I heard her counting out money—I think it was a hundred pounds—and then she went away in the rain.'

I remembered that night upon which Mrs. Darrell had stayed out so long in the rain—the night that followed her stormy interview with Angus Egerton.

I told Peter that he had done quite right in telling me this, and begged him not to mention it to any one else until I gave him permission to do so. I went back to Milly's room directly afterwards, and waited there for Mr. Hale's coming.

While I was taking my breakfast, Mrs. Darrell came to make her usual inquiries. I ran into the dressing-room to meet her. While she was questioning me about the invalid, I saw her look at the table where the medicine had always been until that morning, and I knew that she missed the bottle.

After she had made her inquiries, she stood for a few moments hesitating, and then said abruptly,

'I should like to see Mr. Hale when he comes this morning. I want to hear what he says about his patient. He will be here almost immediately, I suppose; so I will stay in Milly's room till he comes.'

She went into the bedroom, bent over the invalid for a few minutes, talking in a gentle sympathetic voice, and then took her place by the bedside. It was evident to me that she had suspected something from the removal of the medicine, and that she intended to prevent my seeing Mr. Hale alone.

'You took your medicine regularly last night, I suppose, Milly?' she inquired presently, when I had seated myself at a little table by the window and was sipping my tea.

'I don't think you gave me quite so many doses last night, did you, Mary?' said the invalid, in her feeble voice. 'I fancy you were more merciful than usual.'
