He was surprised to find himself humming as he picked up his briefcase in the black-and-white tiled hallway. A glance in the ornate gilt hall mirror cheered him further. Stephen had never belonged to the dusty corduroys and down-at-heel shoes school of University teachers. Today he was wearing a soft grey tweed suit, and a bright blue shirt without a tie. He looked sleek, and younger than his age even with the threads of grey in his silky hair. Satisfied, Stephen went on into the kitchen to say goodbye to his wife.

Beatrice looked round at him, tucking the loose strands of dark hair behind her ears as she did so. It was a gesture that she had used ever since he had known her, and it still made her look like a schoolgirl.

‘Goodbye, darling,’ Stephen murmured. ‘Have a good day. I might be a bit late – faculty get-together.’ They kissed, automatically, not meeting each other’s eyes. Stephen reached out to touch his younger son’s shoulder as he passed, but Joe jerked his head away. Sulking about something, Stephen remembered, but couldn’t recall what. Five minutes later he was in his car, ready to drive the numbingly familiar ten miles into Oxford.

Beatrice watched him go, half regretfully. Fifteen years felt like a long, long marriage, but her husband still had the power occasionally to make her catch her breath and wish that he would stay. Even though she knew him much better than he knew himself, and that knowledge left no room for illusions, she still half loved him, half craved for him. Well, she reminded herself, the days of ducking guiltily out of whatever they were supposed to be doing and staying at home alone together were far behind them now. Beatrice reached for the tendrils of hair again, then remembered the marmalade on her fingers from Sebastian’s plate. She wiped them slowly on her apron, staring out of the gateway where Stephen had disappeared. She was still tasting, as she did every day, the odd mixture of frustration at her dependence on him and the satisfaction that, in spite of everything, they were still together.

‘Mum? My gym shirt?’ Eloise’s voice came demanding from the doorway. Gratefully, Beatrice stopped thinking and began to rehearse the daily list: clean football kit, riding lesson after school, three things beginning with J for Sebastian to take with him. Another day.
