An American spy in China. Name: Unknown. Status: Sleeper.
He's deep undercover but, so far, the job hasn't been too tough: polishing his Mandarin, drinking every night and falling deeper in love with the beautiful but enigmatic Mei.
Just when he thought life had settled into a pleasant routine, he is called back to Washington and handed a dangerous brief: infiltrate the very core of the Chinese Secret Police. Work alone.
But in Shanghai city you're never alone. Faceless strangers linger in the shadows. No one is safe from the Guoanbo. Not even a spy with no name...
