Within the foul alleyways in no particular order or balance are narrow, barely lit staircases leading to the vertical series of broken-down flats, the average rising three storeys, two of which are above ground. Inside the small, dilapidated rooms the widest varieties of narcotics and sex are sold; all is beyond the reach of the police – silently agreed to by all parties – for few of the colony's authorities care to venture into the bowels of the Walled City. It is its own self-contained hell. Let it be.

Outside in the open market that fills the garbage-strewn street where no traffic is permitted, soiled tables piled high with rejected and/or stolen merchandise are sandwiched between grimy stalls where pockets of vapour rise from huge vats of boiling oil in which questionable pieces of meat, fowl, and snake are continuously plunged, then ladled out and placed on newspapers for immediate sale. The crowds move under the weak light of dull streetlamps from one vendor to the next, haggling in high-pitched voices, shrieking back and forth, buying and selling. Then there are the kerb people, bedraggled men and women without stalls or tables whose merchandise is spread out on the pavement. They squatted behind displays of trinkets and cheap jewellery, much of it stolen from the docks, and woven cages filled with crawling beetles and fluttering tiny birds.

Near the mouth of the strange, foetid bazaar a lone, muscular female sat on a low wooden stool, her thick legs parted, skinning snakes and removing their entrails, her dark eyes seemingly obsessed with each thrashing serpent in her hands. On either side were writhing burlap bags, every now and then convulsing as the doomed reptiles struck out in hissing fury at one another, enraged by their captivity. Clamped under the heavy-set woman's bare right foot was a king cobra, its jet black body immobile and erect, its head flat, its small eyes steady, hypnotized by the constantly moving crowds. The squalor of the open market was a fitting barricade for the wall-less Walled City beyond.

Rounding the corner at the opposite end of the long bazaar, a dishevelled figure turned into the overflowing avenue. The man was dressed in a cheap, loose-fitting brown suit, the trousers too bulky, the coat too large, yet tight around the hunched shoulders. A soft wide-brimmed hat, black and unmistakably Oriental, threw a constant shadow across his face. His gait was slow, as befitted a man pausing in front of various stalls and tables examining the merchandise, but only once did he reach tentatively into his pocket to make a single purchase. Then, too, there was a stooped quality in his posture, the frame of a man having been bent from years of hard labour in the field or on the waterfront, his diet never sufficient for a body from which so much was extracted. There was a sadness as well in this man, a futility born of too little, too late, and too costly for the mind and the body. It was the recognition of impotency, pride abandoned for there was nothing to be proud of; the price of survival had been too much. And this man, this stooped figure who haltingly bought a newspaper cone of fried, questionable fish, was not unlike many of the males in the marketplace – one could say he was indistinguishable from them. He approached the muscular woman who was tearing the intestines from a still-writhing snake.

'Where is a great one? asked Jason Bourne in Chinese, his eyes fixed on the immobile cobra, the grease from the newspaper rolling over his left hand.

'You are early,' replied the woman without expression. 'It is dark, but you are early. '

'I was summoned quickly. Do you question the taipan's instructions?'

'He is fuck-fuck cheap for a taipan!' she spat out in guttural Cantonese. 'What do I care? Go down the steps behind me and take the first alleyway to the left. A whore will be standing fifteen, twenty metres down. She waits for the white man and will lead him to the taipan... Are you the white man? I cannot tell in this light and your Chinese is good – but you do not look like a white man, you do not wear a white man's clothes. '

'If you were me, would you make a heavenly point of looking like a white man, dressing like a white man, if you were told to come down here?

'I would make the point of a thousand devils that I was from the Qing Gaoyan!' said the woman, laughing through half gone teeth. 'Especially if you carry money. Do you carry money... our Zhongguo ren?'

'You flatter me, but no. '

'You lie. White people lie with heavenly words about money. '

'Very well, I lie. I trust your snake will not attack me for it . '

'Fool! He is old and has no fangs, no poison. But he is the heavenly image of a man's organ. He brings me money. Will you give me money?5

'For a service, yes. '

'Aiya! You want this old body, you must have an axe in your trousers! Chop up the whore, not me!'

'No axe, just words,' said Bourne, his right hand slipping into his trousers pocket. He withdrew a US $100 bill and palmed it in front of the snake seller's face, keeping it out of sight of the surrounding bargain hunters.

'Aiya – aiya!' whispered the woman as Jason pulled it away from her grasping fingers; the dead snake dropped between her thick legs.

The service,' Bourne repeated. 'Since you thought I was one of you, I expect others will think so, too. All I want you to do is to tell anyone who asks you that the white man never showed up. Is that fair?

''Fair! Give me the money!'

The service"?

'You bought snakes! Snakes! What do I know of a white man. He never appeared! Here. Here is your snake. Make love!' The woman took the bill, bunched the entrails in her hand and shoved them into a plastic bag on which there was a designer's signature. It read Christian Dior.

Remaining stooped, Bourne bowed rapidly twice and backed his way out of the crowd, dropping the snake entrails in the kerb far enough away from a street light so as not to be noticed. Holding the dripping cone of foul-smelling fish, he repeatedly mimed reaching for mouthfuls as he slowly made his way to the steps and descended into the steaming bowels of the Walled City. He looked at his watch, spilling fish as he did so. It was 9:15; the taipan's patrols would be moving into place.

He had to know the extent of the banker's security. He wanted the lie that he had told a marksman in a deserted office above the harbour walkway to be the truth. Instead of being watched, he wanted to be the one watching. He would memorize each face, each role in the command structure, the rapidity with which each guard made a decision under pressure, the communications equipment, and above all discover where the weaknesses were in the taipan's security. David understood that Jason Bourne was taking over; there was a point in what he was doing. The banker's note had started with the words: A wife for a wife... Only one word had to be changed. A taipan for a wife.

Bourne turned into the alleyway on his left and walked several hundred feet past sights he scrupulously ignored; a resident of the Walled City would do no less. On a darkened staircase a woman on her knees performed the act for which she was being paid, the man above her holding money in his hand over her head; a young couple, two obvious addicts in near frenzy, were pleading with a man in an expensive black leather jacket; a small boy, smoking a marijuana cigarette, urinated against the stone wall; a beggar without legs clattered on his wheeled board over the cobblestones chanting 'bong ngo. bong ngo!' a plea for alms; and on another dimly-lit staircase a well-dressed pimp was threatening one of his whores with facial disfigurement if she did not produce more money. David Webb mused that he was not in Disneyland. Jason Bourne studied the alley as if it were a combat zone behind enemy lines. 9: 24. The soldiers would be" going to their posts. The outer and the inner man turned around and started back.
