This put Luke on his mettle. "Look here, you bantams," he cried, "don't you forget that you've got the High Seneschal's son here, and if you know anything about the widow that's ... well, that's a bit fishy, it's your duty to let me know. If you don't, you may find yourselves in gaol some day. So you just spit it out!" and he glared at them as fiercely as his kindly china-blue eyes would allow. They began to look scared. "But the widow doesn't know we've seen anything ... and if she found out, and that we'd been blabbing, oh my! wouldn't we catch it!" cried Toby, and his eyes grew round with terror at the mere thought. "No, you won't catch it. I'll give you my word," said Luke. "And if you've really anything worth telling, the Seneschal will be very grateful, and each of you may find yourselves with more money in your pockets than your three fathers put together have ever had in all their lives. And, anyhow, to begin with, if you'll tell me what you know, you can toss up for this knife, and there's not a finer one to be found in all Lud," and he waved before their dazzled eyes his greatest treasure, a magnificent six-bladed knife, given him one Yule-tide by Master Nathaniel, with whom he had always been a favourite. At the sight of this marvel of cutlery, the little boys proved venal, and in voices scarcely above a whisper and with frequent frightened glances over their shoulders, as if the widow might be lurking in the shadows listening to them, they told their story.

Now Cornflower was a very valuable cow and the widow had given them special injunctions to look after her, so Toby, leaving the other two to mind the rest of the herd, dashed after her into the thinning darkness and though she had got a good start of him was able to keep in her track by the tinkling of her bell. Finally he came on her standing at the brink of the Dapple and nozzling the water. He went close up to her and found that she had got her teeth into something beneath the surface of the stream and was tearing at it in intense excitement. Just then who should drive up in a cart but the widow and Doctor Endymion Leer. They appeared much annoyed at finding Toby, but they helped him get Cornflower away from the water. Bits of straw were hanging from her mouth and it was stained with juices of a colour he had never seen before. The widow then told him to go back to his companions, and said she would herself take Cornflower back to the herd in the morning. And, to account for her sudden appearance on the scene, she said she had come with the doctor to try and catch a very rare fish that only rose to the surface an hour before sunrise. "But
