It dawned on Li. “Long enough to keep me looking in all the wrong places for months on end, trying to make a connection that doesn’t exist. God!” It was so simple. But anyone who understood the modus operandi of the Chinese police would know that they would follow a painstaking and pedantic process of information-gathering that could take months, even years. “The only connection is that there is no connection,” he said. It was a revelation. He gave Mei Yuan a big hug, and Margaret felt a twinge of jealousy. “How on earth did you think of it, Mei Yuan?”

She glowed with the praise and Li’s attention. “Maybe,” she said, “because I did not have to.”

CHAPTER ELEVEN

I

Thursday Night

Red light refracting in hot humid air hung over the city like a veil as the sun dipped in the west, and darkness drew like a curtain from the east across the Middle Kingdom. Below them the lights of the city twinkled in the dusk. Red tail-lights of traffic in long lines snaked east and west, north and south, the growling of their engines a distant rumble. Somewhere down there, Margaret thought, people were crowding the stalls at the Dong’anmen night market, taking pleasure in eating, happy and free at the end of a working day. She wished she were among them.

They had entered Jingshan Park by the south gate, almost opposite the place where the woman in the blue print dress had been knocked off her bike and Margaret had stopped the bleeding from her severed femoral artery by standing on her leg. They were entering the park as most people were leaving. It would close in an hour. They had followed a winding path up through the trees to the pavilion that stood on the top of Prospect Hill. Halfway up, they had stopped briefly to join a crowd of people watching a very old lady in black pyjamas perform incredible contortions. She had laid a mat on the earth and, lying on her back, had wedged both her feet beneath a pole placed behind her neck, effectively folding herself in two. The crowd gasped in amazement, and there was a little burst of applause. The old lady remained impassive, but she was clearly enjoying showing off the suppleness of her joints and muscles. Margaret had guessed she must be in her eighties.

The pavilion was deserted when they got there, orange-tiled curling eaves supported on maroon-and-gold pillars, late evening sunshine throwing warm light on cold marble. Walking round, beneath the eaves, provided a 360-degree panorama of the city below. It took Margaret’s breath away.
