““When one day fate visits us again, Jessa comes running into Hannah’s house to tell us the news that they’ve caught the serial killer. Her tone is hushed and I try hard not to look at Jude, who is working on the skirting boards. But I can feel the humour in his gaze as it falls on me and I know that I will never live down the fact that I suspected him. When I ask her, “Who?” slightly curious, she’s already out the door looking for Hannah and Tate. “No one important!” she shouts from the other room. “Just some postman in Yass.” I look at Jude’s face and I see it whiten and we vow never ever to tell the others.””
