She has the look of an archetypal farmer’s wife. “Briony Chaplin?” she asks.

The forensic team will follow us up once they’ve assembled their equipment.” Jenny and I lead the way upstairs but before we reach my flat, Zoe stops us. “I’d like you to put these on.” She hands us each a pair of disposable plastic bootie
