‘I’ll come with you,’ offered Quarry.
‘No. I switched it on; I’ll switch it off.’
It seemed to him a long walk across the trading floor to the computer room. He could sense the eyes of everyone like a weight upon his back, and it occurred to him that if this were a sciencefiction movie, he would now be denied access to the motherboards. But when he presented his face to the scanner, the bolts slid back and the door opened. In the cold, noisy darkness, the forest eyes of a thousand CPUs blinked at his approach. It felt like an act of murder, just as it had at CERN when they’d closed him down there all those years ago. Nevertheless, he opened the metal box and grasped the isolator handle. It was only the end of a phase, he told himself: the work would go on, if not under his direction then under someone else’s. He flicked the handle, and within a couple of seconds the lights and the sound had faded. Only the noise of the air-conditioning disturbed the chilly silence. It was like a mortuary. He headed towards the glow of the open door.
As he approached the cluster of quants gathered around the six-screen array, everyone turned to look at him. He couldn’t read their expressions. Quarry said, ‘What happened? You couldn’t go through with it?’
‘Yes, I went through with it. I turned it off.’ He looked past Quarry’s mystified face. On the screens VIXAL-4 was continuing to trade. Puzzled, he went to the terminal and began flicking between the screens.
Quarry said quietly to one of the quants, ‘Go back and check, will you?’
Hoffmann said, ‘I am capable of throwing a goddam switch, Hugo. I’m not so completely crazy I don’t know the difference between on and off. My God – will you look at that?’ In every market VIXAL was continuing to trade: it was shorting the euro, piling into Treasury bonds, adding to its position on VIX futures.
From the entrance to the computer room the quant shouted, ‘The power’s all shut down!’
An excited murmur broke out.
‘So where is the algorithm if it’s not on our hardware?’ demanded Quarry.
Hoffmann didn’t answer.
‘I think you will find that is something the regulators will also be asking,’ said Rajamani.
Afterwards no one was sure how long he had been watching them. Someone said he had been in his office all along: they had seen his fingers parting the blinds, staring out as Hoffmann delivered his speech on the trading floor. Someone else claimed to have come across him at a spare terminal in the boardroom with a mass storage device, uploading data. Yet another quant, a fellow Indian, even confessed that Rajamani had approached him in the communal kitchen and asked if he would be willing to act as his informant inside the company. In the somewhat hysterical atmosphere that was about to overtake Hoffmann Investment Technologies, in which heretics and disciples, apostates and martyrs split into their various factions, it was not always easy to establish the truth. The one thing everyone could agree on was that Quarry had made a grievous error in not having the chief risk officer escorted off the premises by security the moment he had been fired; in the chaos of events, he had simply forgotten about him.
Rajamani stood on the edge of the trading floor holding a small cardboard box containing his personal effects – the photographs of his graduation, his wedding, his children; a tin of Darjeeling tea he kept in the staff refrigerator for his personal use and which no one else was allowed to touch; a cactus plant in the shape of a thumbs-up; and a framed handwritten note from the head of Scotland Yard’s Serious Fraud Office thanking him for his help in prosecuting some tip-of-the-iceberg case that was supposed to herald a new dawn in policing the City but which had been quietly dropped on appeal.
Quarry said hoarsely, ‘I thought I told you to bugger off.’
‘Well I am going right now,’ Rajamani replied, ‘and you’ll be glad to know I have an appointment at the Geneva Finance Ministry tomorrow morning. Let me warn each and every one of you that you will face prosecution, imprisonment and millions of dollars in fines if you conspire in the running of a company that is unfit to trade. This is clearly dangerous technology, completely out of control, and I can promise you, Alex and Hugo, that the SEC and the FSA will revoke your access to every single market in America and London pending an investigation. Shame on you both. Shame on you all.’
It was a tribute to Rajamani’s self-confidence that he was able to deliver this speech over a tin of tea and a thumbs-up cactus without any loss of dignity. With a final sweeping glare of fury and contempt, he thrust out his chin and walked steadily towards reception. More than one witness was reminded of the pictures of staff leaving Lehman Brothers with their possessions in boxes.
‘Yes, go on, clear off,’ Quarry called after him. ‘You’ll find ten billion dollars buys us a heck of a lot of lawyers. And we’re going to come after you personally for breach of contract. And we’re going to bloody well bury you!’
‘Wait!’ shouted Hoffmann.
Quarry said, ‘Leave him, Alex – don’t give him the satisfaction.’
‘But he’s right, Hugo. There’s a lot of danger here. If VIXAL’s somehow migrated out of our control, that could pose a real systemic risk. We’ve got to keep him on side until we can figure it out.’
He set off after Rajamani, ignoring Quarry’s protests, but the Indian had quickened his pace. He just missed him in reception. He caught up with him by the elevators. The corridor was deserted. ‘Gana!’ he called. ‘Please. Let’s talk.’
‘I’ve nothing to say to you, Alex.’ He was clutching his box. His back was to the elevator control panel. He hit the call button with his elbow. ‘It’s nothing personal. I’m sorry.’ The doors opened. He turned, stepped smartly through them and plunged from view. The doors closed.
For a couple of seconds Hoffmann stood motionless, unsure of what he had just witnessed. He walked hesitantly along the corridor and pressed the call button. The doors slid open on to the empty glass tube of the elevator shaft. He peered over the edge, down maybe fifty metres of translucent column, until it dwindled into the darkness and silence of the underground car park. He shouted hopelessly, ‘Gana!’ There was no response. He listened, but he could hear nobody screaming. Rajamani must have fallen so quickly, no one had noticed it.
He sprinted along the corridor to the emergency exit and half-ran, half-jumped his way floor after floor down the concrete staircase, all the way to the basement and out into the subterranean garage and across to the elevator doors. He jammed his fingers into the gap and tried to prise them apart, but they kept closing on him. He stepped back and prowled around looking for some tool he could use. He considered smashing the glass on one of the parked cars and popping the trunk for its jack. Then he saw a metal door with a lightning-flash symbol and tried that. Behind it was a space for storing tools – brushes, shovels, buckets, a hammer. He found a big crowbar almost a metre long, and ran back to the elevator doors and jammed it into the gap, working it back and forth. The doors parted just enough for him to shove his foot in between them, and then his knee. He wriggled the rest of his leg into the space. Some automatic mechanism was triggered and the doors trundled open.
Light falling from the upper floors showed Rajamani lying face down in the well of the elevator shaft. There was a puddle of blood the size of a dinner plate that seemed to be growing out of the top of his skull. His photographs lay scattered around him. Hoffmann jumped down next to him. Broken glass crunched under his feet. There was an incongruous smell of tea. He stooped and grasped Rajamani’s hand, which was shockingly warm and smooth, and for the second time that day tried to feel for a man’s pulse, but again he couldn’t find one. Behind and just above him, the doors rattled shut. Hoffmann looked around in panic as the elevator car began its descent. The tube of light shrank rapidly as the car hurtled down – the fifth floor went, and then the fourth. He grabbed the crowbar and tried to jam it back between the doors, but lost his footing. He fell backwards and lay next to Rajamani’s corpse, looking up at the bottom of the car as it hurtled at him, holding the crowbar upright in both hands above his head like a spear to fend off a charging beast. He felt the oily wind on his face. The light faded, vanished, something heavy hit his shoulder, and then the crowbar jumped and went as rigid as a pit prop. For several seconds he could feel it taking the strain. He was screaming blindly into the absolute darkness at the elevator’s floor, which must have been only inches from his face, braced for the crowbar to bend or slip. But then a gear changed, the note of the motor became a whine, the crowbar came loose in his hands and the car began to rise, accelerating rapidly all the way up its cathedral column of glass, uncovering floor after floor of fresh white light, which poured down into the pit.
He scrambled up and shoved the crowbar back between the doors, working it into the gap, parting them a fraction. The elevator had climbed to its highest point and stopped. There was a clunk, and he heard it start to plunge again. He hoisted himself up and jammed his fingers into the narrow opening. He clung there, feet wide apart, muscles straining. He threw back his head and roared with the effort. The doors gave slightly, then flew wide open. A shadow fell across his back, and in a rush of air and a roar of machinery he launched himself forward on to the concrete floor.
