‘Where is Agnes?’ asked Anne, jumping up.

The Applewoman was nowhere in the room. Yet they had all seen her leave the King.

Giles, still a little crazy with happiness, grabbed Barbara by the hand and dragged her wildly down the stairs to look for Agnes.

Luke and Anne followed. There were a thousand questions they all wanted to ask her: Where she had been all these years; how she knew the King was sick; how the cat came to the Countess’s apartments; how the shell got into the pocket of the tunic. And no end more.

Round and round and down the dizzy, winding stairs they went, gabbling like a lot of children out of school.

But at the bottom they found the courtyard empty under the silent stars.

Agnes was gone.
