So the bonfire had been started by the murderer. That was the way Vera saw it. A mistake. Better to take any incriminating paper away with him and dispose of it carefully. So why the hurried fire in the garden? What was that about? Why the rush?

There were really only scraps of text. Handwritten. By Jenny Lister. The forensic handwriting woman had been certain of that. It said so in the email: I’d be quite happy to appear in court. I’d stake my reputation . . . Blah, blah. Very dramatic. But good enough for Vera.

They’d retrieved three different pages containing text, it seemed, and all three were partially charred, one so severely that they’d been lucky to get anything. The first page was the most intact, but contained what looked like a final paragraph. At least, the writing stopped a third of the way down the page. According to the lab, one corner was burned so the ends of some of the sentences were lost, and they’d re-created the pattern of the writing as accurately as they could on the screen. Vera thought that it wasn’t hard to make out the sense.

to sustain a normal and healthy relationship with his or her own children. However, in the case study described, we see deep problems that were never properly addressed and which would be impossible at this point to solve.

Social-work bollocks, Vera thought. If Jenny had been hoping to write a popular book to explain her job to the layperson, she wouldn’t achieve it with stuff like this. Was she talking about Mattie in this piece? Vera assumed so. In that case, Vera had learned nothing from the notes on this page. Still, assumptions were always dangerous. There was no indication here about the gender of the subject of the case study, and Jenny could have been writing about somebody quite different. Besides, she’d been working with Mattie since she was a child. Would the model social worker really admit that she hadn’t ‘properly addressed’ Mattie’s problems during all those years of intervention?

Vera moved away from the computer and stretched. In the lean-to at the back of the house she could hear rain dripping. The flat roof there leaked when the wind blew from the west. Usually it did blow from the west. She fetched a bucket and a bowl to catch the drips and went back to the office. Outside it was raining more heavily than ever.
