‘Ready?’ DS Forbes says again and this time I sit up straighter in my chair and take a deep breath in through my nose. I can smell DS Forbes’s aftershave and the faintest scent of motor oil emanating from Mark, who’s sitting on the other side of me. I can sense him watching me, but I don’t turn to look at him before I pick up the prepared statement on the desk in front of me. I can do this. I no longer need a hand on my knee.

‘Six months ago today,’ I say, looking straight into the camera lens, ‘on Thursday the fifth of February, my younger son Billy disappeared from our home in Knowle, South Bristol, in the early hours of the morning. He was only fifteen. He took his schoolbag and his mobile phone and he was probably dressed in jeans, Nike trainers, a black Superdry jacket and an NYC baseball hat …’ I falter, aware that some of the journalists are twisting round in their seats, no longer scribbling in their notebooks. Mark, beside me, makes a low noise in the base of his throat and DS Forbes leans forward and puts his elbows on the desk. ‘We all miss Billy very much. His disappearance has left a hole in our family that nothing can fill and …’ I keep my eyes trained on the camera but I’m aware of a commotion at the back of the room. One man is wrestling with another in the doorway. ‘Billy, if you’re watching, please get in touch. We love you very, very much and nothing can change that. If you don’t want to ring us directly, please just walk into the nearest police station or get in touch with one of your friends.’

The producer standing next to the cameraman taps him on the shoulder and signals towards the back of the room. The camera twists away from me and a shout emanates from the doorway.

‘Get off me! I’ve got a right to be here! I’ve got a right to speak.’

Chapter 5

‘What’s Jake doing here?’ Mark stares over the heads of the journalists and several flash bulbs fire at once, lighting up the corner of the room where Jake is remonstrating with a male police officer. ‘I thought you said he was ill.’

‘He was … is. Let me deal with this.’

‘Mrs Wilkinson, wait!’ DS Forbes shouts as I hurry across the room and shoulder my way through the circle of journalists that has formed around my son. I can just about make out the back of Jake’s head. His fair hair is wild and tousled without a liberal application of hair gel. He disappears as a policeman steps in front of him, blocking my view.

‘Excuse me. Excuse me, please.’

The TV cameraman hisses as I push past him but he’s shushed by his producer. ‘That’s the mum, get her in shot.’
