‘Come on,’ he said kindly. ‘I’ll walk you back to Follies. I’d like to drop in and see old Rose for half an hour before Hall.’

Helen nodded dumbly. As they walked together across the Quad the ancient bell, Great Tom, struck six. The long, tolling notes lapped sonorously inside her head, uncomfortably like a knell. Yet Oliver drew her arm snugly through his as they turned down St Aldate’s. He was whistling softy, a single phrase over and over again, as if he was trying to tease the rest of a forgotten theme out of his subconscious. Helen fell into step with him, half carried along by the support of his arm. He was wearing a shabby, brown leather aviator’s coat with a lining of tightly curled sheepskin, and in the warmth of a deep pocket his hand still held Helen’s. Remembering the first of his questions, she knew that this was a moment she would like to freeze for herself. If only it was possible to keep him here, beside her, just like this.

When they reached Follies Oliver handed her elegantly down the steep stone steps to the island, walked up through the silent house and stopped outside her door. His eyes glowed very bright and amused in the darkness.

‘I’ll be back,’ he told her, ‘to check out the bolster before too long. Such uncomfortable, old-fashioned things.’

‘That’s good,’ Helen responded equally brightly. ‘I shall look forward to that.’

Oliver raised his arm in a half wave and turned away again. Helen stood listening until the sound of his footsteps had been swallowed up in the recesses of the house. She heard a burst of radio music followed by a door closing, then silence. The thought of her own cold, empty room was uninviting. Helen slipped down the stairs to the grander spaces of the gallery below.

‘Come in,’ Chloe’s low, musical voice answered her knock at once.

Chloe was sitting curled up in her armchair in a pool of lamplight. There was a red-embered fire burning in the grate and her hair was glowing even brighter in the double warmth of the two lights. She closed her book with an exaggerated gesture of relief and grinned up at Helen.

‘Well, and how did it go?’

It was easy to tell Chloe things. Helen clasped dramatically at her heart and stumbled forward into the light. ‘Wonderful. And awful. He asked me to go to bed with him and I said no. Oh God, Chloe, what shall I do?’ It was half a joke, but only half. Something intriguing had come in to fill a cold, empty space inside Helen, and now she didn’t want to let it go.

Chloe’s eyebrows lifted a fraction. ‘Horny little bugger,’ she said, amused. ‘You were quite right to tell him to get lost. He’ll be back, love, don’t you worry.’
