There wasn’t anything in there then but laths.’

‘What are they?’

‘Narrow boards,’ he said. ‘They go between the plaster and the outside wall of the house.’ Trent reached into the crack in the wall and once again touched the metal which showed dull white in there. The crack was about four inches long and half an inch across at its widest point. ‘They put in insulation, too,’ he said, frowning thoughtfully and then shoving his hands into the back pockets of his wash-faded jeans. ‘I remember. Pink, billowy stuff that looked like cotton candy.’ ‘Where is it, then? I don’t see any pink stuff.’

‘Me either,’ Trent said. ‘But they did put it in. I remember.’ His eyes traced the four-inch length of the crack. ‘That metal in the wall is something new. I wonder how much of it there is, and how far it goes. Is it just up here on the third floor, or…’

‘Or what?’ Laurie looked at him with big round eyes. She had begun to be a little frightened.

‘Or is it all over the house,’ Trent finished thoughtfully.

After school the next afternoon, Trent called a meeting of all four Bradbury children. It got off to a somewhat bumpy start, with Lissa accusing Brian of breaking what she called ‘your solemn swear’ and Brian, who was deeply embarrassed, accusing Laurie of putting their mother’s soul in dire jeopardy by telling Trent. Although he wasn’t very clear on exactly what a soul was (the Bradburys were Unitarians), he seemed quite sure that Laurie had condemned Mother’s to hell. ‘Well,’ Laurie said, ‘you’ll have to take some of the blame, Brian. I mean, you were the one who brought Mother into it. You should have had me swear on Lew’s name. He could go to hell.’ Lissa, who was young enough and kind-hearted enough not to wish anyone in hell, was so distressed by this line of discourse that she began to cry.

‘Hush, all of you,’ Trent said, and hugged Lissa until she had regained most of her composure.
