‘Huh. Yes, something like that. You’d think it was a boring nine-to-five, wouldn’t you? But no. He works such a lot; unsocial hours … often away.’ She gives a short snort of a laugh. ‘There! Pull up over there a minute,’ she yells, causing me to panic so much I almost make an emergency stop.

I indicate and stop just outside Sports Direct. It’s double yellow lines and the car park is only around the corner. ‘I can’t park here, Dav—’

‘We’re not parking, we’re waiting. Look!’ Davina points.

Carl is walking in the direction of the car park.

‘What are we going to do, follow him?’ I laugh, but know that’s exactly what Davina has in mind. The adrenaline rushes through my body.

‘Absolutely we are,’ she says. I can’t help but smile. This is possibly the most excitement either of us have had in a while. My house issues aside.

‘I can’t see him now, though. How are we going to know when he’s driven out?’

‘Let’s give it a few minutes, then drive slowly in that direction.’

We do this and as I’m approaching where the exit of the car park joins the road, I spot Carl’s car.

‘Good,’ Davina says. ‘Right, there’s a few cars behind him waiting to drive out as well. Make sure a couple are between you and him.’

‘God, Davina. Have you done this before?’

‘I watch a lot of crime films and documentaries for research.’

Of course, that makes sense. I manage to keep two cars behind Carl and get through the next set of traffic lights at the same time as him. So far, so good.

‘What are we hoping to gain by following him?’ I ask.

‘I don’t really know – but it seems like a good idea.’

I haven’t yet told Davina what I learned from Yolande in the playground. Now might be a good time. I explain how the conversation went; Davina remains quiet while I retell it.

‘So, I was actually coming over this morning to ask you if you knew about this affair Carl was having, then when you came up with this plan, I completely forgot to ask.’

Davina is so quiet I have to nudge her to make sure she’s even heard me. ‘Did you know about it?’ I ask again. She seems to be deep in thought, manically twiddling her damn cardigan again, but eventually she speaks.

‘I had my suspicions, but no. I didn’t know about that affair,’ she says, her voice flat.

From her choice of words I suspect she maybe knew about a different affair; with someone other than Miss Emery.

‘I thought you always had your finger on the pulse of Stockwood.’ I laugh.

‘I’m not as nosy as you think I am, Amber.’
