far as she can manage. She cannot think of an alternative. On the map, the river does not look far from Jin’s flat. She must merely keep walking east until she runs into the Thames at a place called Isleworth. But when she emerges out onto the street, she quickly becomes disoriented; walking in a straight line is not as simple as she thought. She mustrefer to the map book constantly if she wishes to remain on course. Eventually she holds it open in front of her as she walks, checking the names of streets carefully at each intersection.
By the time she reaches Isleworth and the river, she is already tired. But unlike Hounslow, it is very picturesque. Brightly painted old buildings line the shores of the Thames, and a pretty church with spires rises up beside the river. There is nowhere at home that looks like this, she thinks, pausing for a moment to look out upon the swiftly flowing water. In the distance to her right she spies her first two bridges. The near one is low, modern and relatively plain. Though she can see some pale green railings, she does not think it could be the one her brother spoke of. The one behind it, further down river to the south, appears to be a railway bridge, and therefore closed to pedestrians. With a sigh she turns and begins to walk upriver. Two down, she thinks resolutely. Only eighteen more to go.
After half an hour, she passes another bridge, painted red and white. Both sides of the river are lined with parkland here. A gravel path runs beside the water, and for a time she forgets that she is in the middle of a large city. She passes the occasional jogger or cyclist, and a trickle of other walkers, but for the most part she is alone. She and Wen grew up in a small village just outside the city of Tangshan, a three-hour drive south-east of Beijing. A river ran along the outskirts of their village. When they were young, it was clean enough to swim and fish in. But as the region developed, the water became polluted with run-off from factories. Eventually it carried a thick skin of industrial effluent, so dense that birds could alight on it and ride downstream.
The Thames here looks better, she thinks, though not something she would swim in. The late September day is warm and sunny; she has finished the small bottle of water she brought with her and is beginning to get hungry. She follows the path around bend when suddenly a bridge comes into view. She stops short. Itis a tall suspension bridge: graceful, delicately wrought, with two enormous iron spires stationed like guards on either end. The entire bridge is painted green. At once she knows that it is Wen’s.
Quickly she checks the map book. She is just beside Hammersmith. She follows a path that takes her up to the bridge and walks out to its centre, just as Wen must have done countless times. From there she has a good view upriver. The tide is low and there are few boats in sight. A small sailboat drifts along lazily in the distance. She stares down at the map book: she does not know which side of the river Wen’s restaurant was on, but decides on balance to head towards the centre of London.
Minutes later, she regrets this decision, as she finds herself caught in a series of concrete underpasses with cars whizzing by her in every direction. But she perseveres and eventually emerges onto a high street with shops and restaurants. Hungry, she goes into a small sandwich bar, though once inside, she is bewildered by the display of fillings inside the glass case, most of which she does not recognise. A dark-haired man behind the counter raises a bushy eyebrow at her. Lili flushes and turns away.
She carries on walking, and after a few more minutes she sees a small Chinese restaurant on the opposite side of the road. The sign in English reads Taste of Spring , though the Chinese characters across the shop’s front say Fragrant Spring Joy . She hurries over to it and peers through the window. She sees with disappointment that the
