Emily picked up a big piece of iron, in a corner, so heavy she could hardly carry it:

“Do you know what I’m going to do?” she asked in a strange voice.

At the sound of it Rachel stopped scratching and looked up.

“No,” she said, a trifle uneasily.

“I’m going to kill you! I’m turned a pirate, and I’m going to kill you with this sword!”

At the word “sword,” the misshapen lump of metal seemed to Rachel to flicker to a sharp, wicked point.

She looked Emily in the eyes, doubtfully. Did she mean it, or was it a game?
