The Bennet flat needs processing. Had Dru been forced to participate in getting rid of the body? Or cleaning the floor? One of them had had to collect Grace’s belongings from the help flat, without Katja or Mum or Max seeing. My stomach hurt.But CSI had come and gone. They’re back at the lab already. The hair from the hammer is indeed a superficial match with the hairs from Grace’s brush, just as Keene had eyeballed. The brand of hammer matches a brand popular in Mr. Bennet’s admittedly haphazard tool collection. It’s suggestive. You can say that with authority if you’re a prosecutor, or a sneer if you’re the defence.I’m parked on the grounds of the school, facing across Trumpington Road. I look through the windscreen towards the brook beyond. Why would he bring it all the way here? I can understand avoiding the original dump site, and the rain in which he’d dumped the body had kick-started the flooding that closed that road, anyway. But why not with Grace’s things, which Keene had found?
