‘No, indeed,’ said Giles quickly. ‘You look to me like a very—er—sensible woman. But we can’t quite understand those cats. That one over there, now, he has a sort of queer, creepy look in his eyes when he stares at me. Seems almost as though he were listening, taking in everything that’s said.’

Agnes chuckled.

‘Would you like him to come over here and join us by the fire? ... All right. Here he comes, look.’

The big sleek creature, with the firelight glinting green in his eyes, stalked slowly across the floor and planted himself solemnly at Giles’s feet.

‘But there you are!’ cried the boy. ‘You didn’t call him, you gave him no order, and yet he came as soon as you wanted him. How do you do it?’

‘You mean, how does he do it?’ said Agnes. ‘Well, I’m not sure that I know, myself. They are a pair of ordinary cats to look at, as you see. Larger than most—but very much cleverer. They were born twins, kittens from the same litter, you know. Perhaps it’s because we have lived together so long. They are older than either of you. And they are both very fond of me—quite jealous about it, sometimes, it would seem. Though, strange to say, they never fight and have never cried or made a single sound since I’ve had them. When they were younger I used to teach them all manner of tricks. It was very easy with such clever creatures. But now they seem to teach themselves—or one another. Sometimes I fancy that they are continually on the watch to know, or guess at, what I want, what I am going to do next. And that seems to sharpen up their wits. For anyone can see that they watch one another as well as watching me. But, be that as it may, they certainly often carry out my wishes without being told. And, after all, what’s strange about that? The same thing happens with people. But we are getting away from your father and his troubles.’

‘You will be able to help him, yes?’ asked Anne eagerly.

‘Well, now,’ said Agnes, ‘wait a minute. First of all I want you children to have one or two things quite clear in your minds. Since I am called a witch, I am in daily danger of being hauled up before the magistrates and perhaps even of being burned for my sins.’

Both the cats suddenly sprang on to her lap together. Anne fancied that one looked fierce and the other looked sad. Agnes smiled, patted them and pushed them gently down.

‘Therefore,’ she went on, ‘it is necessary that we go about the matter with much care. For there may be danger in it—for you and others. I don’t want you to tell any lies, to your parents or anyone else. But for the present I want you to keep your little mouths shut very tight.’
