Craig doesn't answer, but hurries down the stairs. "Where is it? Where is it?" His voice starts to raise, then he must have spotted the package, and falls silent. She can hear how he all but runs up the stairs and then hears his door slam - he must have pushed it close with his hands still carrying the book, as soon as he was inside his room.
The music is turned down soon so she doesn't catch it outside his room anymore - just outside his window, and even there it is faint. Craig stays inside his room the whole afternoon.
