She could have sworn that the baker's boy with the tray of loaves on his head was not whistling, that the maid-servant, leaning out of a window to tend her mistress's pot-flowers, was not humming the same tune that they would have been some months ago.

This, perhaps, was natural enough. Tunes, like fruit, have their seasons, and are, besides, ever forming new species. But even the voices of the hawkers chanting "Yellow Sand!" or "Knives and Scissors!" sounded disconcertingly different.

Instinctively, Dame Marigold's delicate nostrils expanded, and the corners of her mouth turned down in an expression of disgust, as if she had caught a whiff of a disagreeable smell.

On reaching the Guildhall, she carried matters with a high hand. No, no, there was no need whatever to disturb his Worship. He had given her permission to visit the prisoner, so would the guardian take her up immediately to her room.

Dame Marigold was one of those women who, though they walk blindfold through the fields and woods, if you place them between four walls have eyes as sharp as a naturalist's for the objects that surround them. So, in spite of her depression, her eyes were very busy as she followed the guardian up the splendid spiral staircase, and along the panelled corridors, hung, here and there, with beautiful bits of tapestry. She made a mental note to tell Master Nathaniel that the caretaker had not swept the staircase, and that some of the panelling was worm-eaten and should be attended to. And she would pause to finger a corner of the tapestry and wonder if she could find some silk just that powder blue, or just that old rose, for her own embroidery.

"Why, I do declare, this panel is beginning to go too!" she murmured, pausing to tap on the wall.

Then she cried in a voice of surprise, "I do believe it's hollow here!"

The guardian smiled indulgently—"You are just like the doctor, ma'am—Doctor Leer. We used to call him the Woodpecker, when he was studying the Guildhall for his book, for he was for ever hopping about and tapping on the walls. It was almost as if he were looking for something, we used to say. And I'd never be surprised myself to come on a sliding panel. They do say as what those old Dukes were a wild crew, and it might have suited their book very well to have a secret way out of their place!" and he gave a knowing wink.

"Yes, yes, it certainly might," said Dame Marigold, thoughtfully.

They had now come to a door padlocked and bolted. "This is where we have put the prisoner, ma'am," said the guardian, unlocking it. And then he ushered her into the presence of her old schoolmistress.
