Vera left the Land Rover in Harbour Street and got a lift to North Mardle beach in an unmarked car. A hunch. This was where Malcolm had made promises to Margaret Krukowski, and this was where he came to think. She needed to talk to him before he did anything stupid. The light had almost gone, but the sky had cleared. As the cloud thinned the temperature had dropped, and there were strange white ponds in the bowls formed by the sand at the top of the dunes. Places where hailstones had pooled and frozen. There was a big white moon. Perhaps Kate Dewar would write another song just for the season.

Vera found a vantage point in the dunes. She could see the car park behind her and the beach in front. Further south there were the lights of Mardle town centre and the harbour wall. Out in the bay a boat was moored and on the horizon was a huge container ship making its way towards the Tyne. No sound. Not even of surf on the beach, because there was no wind and the tide slid in like oil. Tomorrow was Christmas Eve and it seemed that everything was breathless, waiting.

Vera’s phone pinged. A text from Holly: Kerr has collected his car from Partington. One passenger. A name. Which meant, Vera thought, that Malcolm wasn’t thinking straight if he hoped to avoid being picked up. More likely, he no longer cared what happened to him. She sent a text in return: In place. Keep your distance.

She supposed that she was taking a risk. Perhaps they should pick him up immediately, go in mob-handed, blues and twos. The press and her boss would like that. But she still sensed that Malcolm felt trapped and desperate and had no concern for his own safety. Again, like a mantra or a popular song, the chorus flashed into her head: No more killing.

She waited. Nothing. No sound of a car in the distance, and surely they should be here by now if Malcolm had come straight from Partington. It was only a couple of miles away. Occasionally she believed she heard something – footsteps in the frozen sand, or the rumble of an engine – but it was all in her imagination. She was chilled despite her thick coat and her gloves and boots. If Malcolm should appear now, she wasn’t sure that she’d be able to move.
