It’s difficult not to get anxious whenever Sienna hears any sound in the house. She’s safe: nobody is coming for her; there’s no reason for them to. She turns her attention to getting everything ready for Jackson leaving tomorrow. She should do his washing; prove to Holly that she can look after him so that she agrees to make this a regular arrangement. Sienna’s sure it will help Holly out to have extra childcare.

Upstairs, she tidies his room, gathering all his clothes together. A scraping sound downstairs makes her freeze, her breath catching in her throat. She has nothing to defend herself with if someone’s broken in. She waits to hear it again, but everything is silent. She needs to check downstairs. Scooping up the pile of Jackson’s clothes she’s collected, she spots a red T-shirt sticking out of his rucksack, which he’s left on the floor by the bed. She pulls it out and something drops to the floor. Bending down to pick it up, she’s puzzled when she sees what it is.

A bank debit card.

Dropping the clothes on the floor, she turns it over and stares at the name on it.

Gregory Michael Wells.

It takes a moment for the realisation of what this means to hit her, and when it does, Sienna drops to her knees.

It’s minutes before she can pick herself up from the floor. In her hands is Greg’s debit card, the one that was used in Brighton. The police have never believed it had actually been Greg who’d used it, but she had wanted to cling on to this hope. Until it hadn’t been in his wallet when they’d found his body.

What she’s struggling to comprehend is why it’s in Jackson’s possession. Did he see Greg before he disappeared? Does he know something? It doesn’t make sense. All she knows is that somehow Jackson is right in the centre of this and she needs to confront him. He’s still a kid, though; she needs to be careful.

It’s nearly three p.m. and Sienna realises that Holly will be landing soon. Sienna will talk to her about this first and let her be the one to confront her son. Still, she searches through the rest of Jackson’s belongings, rooting through every pocket without feeling a shred of guilt. She finds nothing else, and she abandons the idea of washing Jackson’s clothes. It seems pointless now – trying to prove she’s a good stepmother when she’s about to approach Holly with something so awful.

A car pulls up outside, and Sienna rushes to the window. Part of her is hoping that it’s Abby, even though she knows Abby is well on her way to Ipswich by now.

It’s at least two hours too early but it’s Holly’s black Audi in the driveway.
