‘Love the sound of it,’ said Chloe, ‘but does such a sum of perfection do anything as ordinary as have tea?’

The sound of their laughter reached Rose as she slid across the dark hallway below, and it brought a flicker of a satisfied smiled to her broad face.

‘Now I’m sitting here drinking champagne and talking to you as if I’ve always known you,’ Helen went on. ‘Odd, isn’t it? It feels a long way from home, too, and that isn’t fair.’ The sadness flooded back into her face.

‘Listen to me, Helen,’ Chloe said firmly. ‘It would be wrong to destroy the value of being back here by immersing yourself in guilt and grief. That would make your family’s sacrifice useless, wouldn’t it? You can’t forget your father’s death – how could you? – and you shouldn’t try. But you can find your own strength to carry on positively, where he couldn’t.’ Chloe broke off and bit her lip. Her face reddened as she met Helen’s serious straight gaze. ‘I don’t know why I’m preaching at you,’ Chloe said uncomfortably, ‘particularly when I’ve got the feeling that there are several things for me to learn myself before too long.’

The silence stretched on for a second or two before Helen broke it. ‘You’re right, though. Thank you, Chloe. Tea on Friday with Oliver,’ she added lightly. ‘I’ll have to be profoundly positive to cope with that. Will you … do you think you could lend me something beautiful to wear?’

There was relief in Chloe’s face as she responded warmly, ‘With pleasure. To seal the deal, let’s go out and eat now – I’m ravenous. You tell me where’s good, and I’ll treat you. Okay?’

‘Sounds wonderful.’

The two girls left Follies House together and climbed the cold, slippery steps up to the bridge. Inside her Renault, Chloe revved the engine decisively and glanced at Helen’s profile beside her. ‘Well then, Oxford, here we come,’ she murmured into the icy air.

On Friday afternoon Helen slipped through the great wooden gates of Christ Church and crossed to the porter’s glassed-in box, incongruously snug under the splendour of Wren’s tower.

‘Oliver Mortimore’s rooms, please?’ she asked, remembering that Oliver had made no mention of where he was to be found. Perhaps he just assumed that everybody knew.
