There was one other thing to set out: a small nativity scene, showing Mary leaning protectively over the crib, her face glowing as she watched her child. Alysa had bought it on the way home as an expression of her joy.

Gently she laid it on a shelf, close to the tree so that the lights fell on it, illuminating the baby’s face. He looked up at his mother, perhaps even smiling. Alysa tried to dismiss the thought as fanciful, but it returned, whispering of happiness to come.

Why didn’t James hurry? He was an hour late, and she loved him so much, every moment in his company was precious. But he would be here soon-very soon.

For the hundredth time she checked that everything was perfect, including her appearance. For once she wore her long hair flowing freely. Usually it was pulled back and wrapped up in a chignon. She kept meaning to cut it short and adopt an austere style, suitable for her job as an accountant. But she’d always deferred the decision, possibly because she knew that her hair was her chief beauty.

She had never been pretty. Her face was attractive but, to her own critical eyes, her features were too strong for a woman.

‘No feminine graces,’ she’d often sighed. ‘Too tall, too thin. No bosom to speak of.’

Her women friends were scandalised by this casual realism. ‘What do you mean, too thin?’ they’d chorused. ‘You’ve got a figure most of us would die for. You could wear anything, just like a model.’

‘That’s what I said-too thin,’ she’d responded, determinedly practical.

But then there was the hair-rich brown, with flashes of deep gold here and dark red there, growing abundantly, streaming over her shoulders and down to her waist, making her look like some mythical heroine.

James loved her hair, which she’d been wearing down when they’d first met.

‘I couldn’t take my eyes off it,’ he’d told her afterwards. ‘One look and I began scheming to get you to bed.’
