But what about her? Who was there to worry about Yvonne? Her entire world crumbled and she was required to get on with it like nothing happened and then, a decade later, be happy to drag it all back up again.

‘I need to go.’ She puts the phone down and lays her head on the desk. The residual heat of his voice tickles her ear. She should have hung up straight away. She should never have listened to him.

‘Ms Olsson?’ The intern never knocks. ‘Are you okay?’

Yvonne flicks her head up. ‘Yes, fine. I have a headache.’

‘You need a paracetamol?’ A look of genuine concern etches its way across her young face.

‘No. No, thank you.’ Yvonne turns to the window, to the dull blanket of drizzle.

‘I’m sorry about the call. Your brother said it was important, so I wasn’t sure,’ the girl rambles. ‘Did I do something wrong?’

Yvonne needs to get out. She grabs her bag from the floor, jacket from the back of the seat and brushes past the girl without another word. On the street outside she is grateful for the chill, for the way it clears the build-up of tension in her forehead. She walks away from the office towards a little park tucked between groups of council blocks.

Yvonne finds a damp bench, partly sheltered by a tree, opens her bag and takes out her phone. After their meeting ended so abruptly last week she never expected to hear from Kiama again, but then last night there was one message after another. Each one detailing some vague plan for the ten days he will spend in Kenya, from visiting his grandparents in Nairobi, to eating at a particular beach bar in Mombasa. He also wants to spend time with Purity, the woman who cared for him so closely during the six months he spent there.

When he first mentioned Kenya at the coffee shop Yvonne never even thought to ask him where Lewis stood on all this. It never crossed her mind that he would have been kept in the dark about the trip. Why wouldn’t Kiama have told him?

But Kiama’s reasons for going back to Kenya are so unclear. It has to be about more than filling in the gaps from his memory and meeting up with his grandparents. When Yvonne questioned him he briefly mentioned a book he’d read about someone who got over a childhood trauma by returning to its source as an adult. But he seemed embarrassed by this and shrugged it off when Yvonne probed him. It was only later that evening she realised he was talking about one of Lord Mountbatten’s grandsons who survived a terror attack. But it wasn’t the same thing, not at all.
