Terry Boot Longbottom, once known as boot

Y'know what Sally Anne's been saying about my Mum? I think she may be right. Mum's acting dead strange tonight. And she's staring at the clock that tells whether any of us is in danger. She thinks we don't know what she's doing, but she's shouting at anyone who makes a noise, and she's told us all we have to stay inside and in the back room, but no one's allowed into the kitchen or the lounge or upstairs or anything. And she means it, too, because she went absolutely shouty crackers about an hour ago when Percy went in the kitchen to see about some tea.

I don't know if it's anything to do with Black, but there's something big happening and no mistake.
