‘I don’t know,’ she said simply. ‘How can I be? By now it should be all behind me, and yet-somehow it isn’t.’

He nodded, and the sight gave her an almost eerie feeling, as though she and this stranger were linked by a total understanding that reduced everything else to irrelevance.

‘Is that why you came?’ she asked.

‘Partly. I also came for my daughter’s sake.’

He indicated the child standing a little way off with an elderly woman who was leaning down, talking to her. It was the same child who’d been in the picture, a year older.

As Alysa watched, the two moved across to where the flowers lay, so that the little girl could lay down her posy in tribute. Looking up, she saw her father, and she smiled and began to run towards him, crying, ‘Poppa!’ At once he reached down to pick her up.

Alysa closed her eyes and turned slightly. When she opened her eyes again the child would be out of her sight line. Something was happening inside her, and when it had finished she would be all right. It was a technique she’d perfected months ago, based on computer systems.

It started with ‘power up’ when she got out of bed, then a quick run-through of necessary programs and she was ready to start the day. A liberal use of the ‘delete’ button helped to keep things straight in her head, and if something threatened her with unwanted emotion she hit the ‘standby’ button. As a last resort there was always total shut-down and reboot, but that meant walking away to be completely alone, which could be inconvenient.

Luckily, standby was enough this time, and after a moment she was able to turn back and smile in a way that was almost natural. She could do this as long as she aimed her gaze slightly to the right, so that she wasn’t looking directly at the child.

Drago was absorbed in the little girl, whom he was holding up in his arms. Alysa marvelled at how his face softened as he murmured to his daughter, words she could not catch.
