Li parked and locked his bike and entered the block where he lived with his uncle—superior apartments, behind high Ministry walls, reserved for top Ministry officials and senior police officers. It was late and the elevator was turned off for the night. Li unlocked the stair gate and climbed the two flights to their apartment. There was still a singing in his ears from the music in the club and his hearing felt woolly and dull, but even as he opened the door, he could hear the deep rumble of Old Yifu’s snoring coming from the further bedroom. He went first into the kitchen, where he took a bottle of chilled water from the refrigerator and drank deeply, washing away the bad taste of cigarettes and beer, and then into his bedroom, where he sat on the bed for fifteen minutes or more, thinking, about the day that had just passed, about the day that lay ahead. He was tired, but not remotely sleepy. There was an ache at the back of his head, and acid burned his stomach.

He tipped forward and slid open the top drawer of a dark-wood utility dresser. Under an assortment of clean underwear, he found the collection of leather strapping he was looking for and pulled it out. He had never worn it beyond the first time he had tried it on. He had adjusted the buckles then so that it still fitted neatly to his shoulder, soft tan leather straps holding the holster firmly in place. It had been a gift from his lecturer in Chicago, a full-time cop, part-time lecturer, who had taken a shine to him and arranged for him to sit in the back of a squad car over several night shifts. It had been an extraordinary experience, frightening, sometimes bloody, often intimidating. It had opened his eyes to a crime culture and the means of combating it that was unknown in China. These cops were as hard and ruthless as the petty criminals, muggers and pimps, junkies and prostitutes they had to deal with. It was a world, Li reflected now, almost shocked by the thought, with which Margaret must be only too familiar. He wondered how it was possible to endure prolonged exposure to it without suffering lasting damage. He saw the soft, freckled skin of her forearm, the unfettered breasts pushing against the thin cotton of her tee-shirt, a recurring vision that somehow emphasised her soft, vulnerable femininity. How long could that survive in the dark, creepy-crawly world she inhabited beneath the rock of civilised Chicago society? How long before the shell she would make to protect herself from it enveloped her completely, making her, like the cops he had shared the night shift with, cynical and hard beyond redemption?
