"Are you the babysitter?" Awful Sykes asked, directing a look at her visitor such as a lioness might have turned on a gazelle.
Ace didn't seem to notice. "That's right," she said.
"Dad never learns. The last one lasted eight minutes forty seconds."
"Takes me back," Ace said. "I got my record down to seven. So what're you going to do to me? Itching powder?"
Awful gave her a long look. "What did you use?"
"Nitrogen triiodide. One touch and boom. I could show you how to make it."
Ace nodded. "But I'm not telling you for nine minutes."
