`Is it hard to administer?’
`Tricky,’ Nordmann said. `There are two different chemicals, atropine and parladoxime. They have to be balanced.’
Graves sighed. `So the antidote is a binary, too.’
`In a sense. The two chemicals treat different effects of the gas. One treats the peripheral nervous system, the other the central. The chemicals are dangerous in themselves, which makes it all much harder.’
`Fighting fire with fire?’
`In a sense,’ Nordmann said.
The two men stood staring out the window at the apartment opposite. Phelps was in a corner using a walkie-talkie. `You in position?’
A response crackled back. `In position, sir.’
`Very good.’ Phelps clicked off the walkie-talkie. `We’ve got two cops stationed outside the door to that apartment,’ he said.
`Fine,’ Graves said. `Just so they don’t get too close to the door.’
`I have them ten feet away.’
`That should be fine.’
In the hallway outside Wright’s apartment, officers Martin and Jencks of the San Diego Police Department stared at the closed door and leaned against the wall.
`You understand any of this?’ Jencks said.
`Nope,’ Martin said.
`But they said not to get too close to the door.’
‘That’s right.’
`You know why?’
`I don’t know nothing,’ Martin said. He took out a cigarette. `You got a match?’
`Maybe we shouldn’t smoke . . .’
`Who’s going to know?’ Martin said.
Jencks gave him a match.
Graves stood with Nordmann in the surveillance room across the street.
‘Wright booby-trapped the apartment?’
`Elaborately,’ Graves said. `He told me some of it. I’m sure he didn’t tell me everything.’
`And it goes off at five?’
`Yes.’
`Forty-five minutes from now,’ Nordmann said. `Is the Navy sending people with protective suits? Because protected people could just walk right in.’
`Nobody can walk right in,’ Graves said. `He’s wired the room with explosive. That’s why we’ve got the guards over there.’
Nordmann grimaced. `Explosive?’
`Twenty pounds of it.’
The TV in the corner of the room showed the Convention. A monotonous voice was saying, `Mr Chairman . . . Mr Chairman, we request the floor . . . Mr Chairman. . .’ There was the loud banging of a gavel.
`Turn that damned thing off,’ Graves said. Someone turned it off.
At the window two men grunted as they lifted a huge lens onto a heavy-duty tripod. It was screwed into place and adjusted. `Ready, Mr Graves.’
`Thank you.’ Graves went to the window.
`What’s that?’ Nordmann said.
`A fifteen-hundred-millimeter telephoto,’ Graves said. `It’s the best look we can get.’
He peered through the giant lens. The view was so enormously magnified that at first he didn’t know what he was looking at. Using a fine-knurled knob, he moved the lens and saw he was focused on a crack in the floor. He moved across the floor to the boxes. He shifted the lens upward, examining each box in detail.
`Take a look at this,’ he said, stepping away.
Nordmann squinted through the lens. `Three stacked boxes,’ he said. `I can’t make out much. . .’
`Neither can L’ Graves folded his arms across his chest and stared out the window. He tried to think logically, but he was having trouble; Wright’s death had unnerved him, whether he wanted to admit it or not.
And the system seemed so complicated. Staging sequences, timers, vibration sensors, explosives . . . His head ached. How the hell would he unravel it?
`Let’s work it backward,’ Nordmann said. `What’s the most important element in the system?’
`The gas.’
`How is it controlled?’
`There are spring-loaded valve mechanisms. They can be tripped by a solenoid.’
`And they presumably have a timer of some kind.’
`Presumably.’
`Battery-powered or line-powered?’
`Well, he’s plugged one of the boxes into the wall. But the valve mechanisms are probably batterypowered.’
Nordmann nodded. `That makes sense,’ he said. `He wouldn’t have the most important elements dependent on an external system. So what did he plug into the wall?’
`I don’t know.’
`Vibration sensors?’
`Maybe,’ Graves said. He looked at his watch. It was 4:20. He would have to move soon. What had Wright expected him to do? The psychological report was folded up in his pocket. He took it out and looked at the last few lines.
IF THERE ARE ANY DEFECTS OR HIDDEN FLAWS IN HIS BEHAVIOUR, THEY ARE HIS IMPULSIVENESS AND HIS DESIRE TO FINISH A TEST SITUATION RAPIDLY.
Well, he didn’t have much choice now. He was going to have to make a move, and soon.
`You know,’ Nordmann said thoughtfully, `most of the equipment in that room is defensive. It’s designed to keep people out of there until the gas is ready to be released. But I suspect some of those defences . are meant to be penetrated.’
`I agree,’ Graves said. `And in any case, we have to start penetrating.’
`Wall current first?’ Nordmann asked.
Graves nodded. He glanced at Phelps, who was sitting in a corner of the room literally chewing his nails. Graves sent Lewis across the street to disconnect power to the apartment. Four minutes later, the power was off. Graves watched through the big telephoto lens. He saw a single yellow pilot light in the vibration sensor box go out.
`Well,’ Nordmann said, `that’s a start. We’ve killed part of the system.’
`Have we?’ Graves said. He watched through the telephoto as the solenoid mechanism tripped open the tank valves, then a moment later tripped them shut.
The apartment became filled with whitish gas.
`What’s happening?’ Phelps said, very agitated.
`Quick,’ Graves said. `Those cops. Tell the cops.’
`What cops?’ Phelps said.
Officer Martin finished his cigarette and ground it out on the floor. His heel squeaked.
`Sssh,’ Jencks said, suddenly tense.
`What is it?’
`Sssssh. Listen.’
The two men listened in silence. There was a hissing. `You hear that?’ Jencks said.
`Yeah. It’s coming from the room.’
`Are you sure?’
Martin moved closer to the door. `I think so -‘
`Maybe you shouldn’t -‘
Martin began to cough. His nose ran. `Shit,’ he said. `What is this?’ He coughed again.
Jencks went forward to help him. Then Jencks felt the stinging in his nostrils, and the liquid began to pour over his shirt. He didn’t know a nose could run that way. His eyes ached and stung; he felt dizzy. `What the hell . . .’ He had a coughing fit.
The walkie-talkie crackled. `This is Phelps,’ a voice said. `Over.’
Martin took a step towards the walkie-talkie and fell to the floor. Now he could see the faint wispy whiteness seeping through the door.
`This is Phelps. Over.’
Jencks was coughing loudly and groaning.
Martin stretched out his hand towards the walkietalkie. He was weak. His arm trembled. Then, without warning, he vomited and lost consciousness.
`I’m not getting an answer,’ Phelps said.
Graves and Nordmann exchanged glances, then looked back out the window at the opposite apartment. The room now had a faint milky haze.
`Are they dead?’ Phelps said.
`Probably.’
`How can you just stand there?F
‘Because,’ Graves said, `it was just a short burst. The valves are turned off again.’
Phelps looked puzzled.
`It wasn’t a full release,’ Graves said. `It’s just a partial release, to fill the room with gas. That’s why Wright carefully closed the windows. Now we really can’t get in there.’
`You sound so appreciative,’ Phelps said.
`I’m not. But we understand now what Wright meant by a complex staging sequence.’
`God damn it, this is not a jigsaw puzzle! Two cops have died and -‘
`We’re all right,’ Nordmann said quietly, `until five PM.,
‘And what do you intend to do between now and then?’ Phelps demanded angrily. `I’m going to call the Navy,’ he said. `Their men were supposed to be here an hour ago. It’s four thirty now.’
Graves stared at the gas-filled apartment. He had a brief mental image of the two cops staggering drunkenly in the hallway. He pushed it away; he could consider it later.
Beside him Nordmann said, `It’s really quite clever.’
Graves said, `How thick is the gas in that room?’
`Hard to say,’ Nordmann said. `The normal colour of the gas is white. I don’t think the density is very great. Why?’
`If you shot me full of those antidotes, could I survive the atmosphere in that room?’
`I don’t know.’
`Would I have a chance?’
`A chance? Of course. But even if you could survive, how would you get in? You said yourself it’s wired with explosives. You can’t go in the front door.’
`I wasn’t thinking of the door,’ Graves said. `I was thinking of the window.’
`The window?’ Nordmann frowned. `I don’t know
. .Graves looked down at the street below, where an ambulance had pulled alongside the wrecked Alfa. A half-dozen cops and orderlies were trying to open the door, but it was still jammed shut. `Damn,’ he said. `I wish he were still alive.’
`It probably wouldn’t matter,’ Nordmann said absently. He was staring across at the other building.
Graves said, `How good are my chances with the antidote?’
`Four thirty-five,’ somebody said.
`Maybe one in two,’ Nordmann said. `At best.’
`All right. Let’s do it.’
`Are you sure?’
‘What choice do I have?’
Nordmann considered this, then nodded. `Sit down,’ he said. `I’ll fix a syringe.’
He quickly filled a syringe with two solutions, one pale yellow, the other clear.
Graves sat and watched him. `How do I take it?’
`Intravenously.’
`You mean, in the vein?’
`Yes.’
`I can’t possibly shoot into my veins.’
`You can,’ Nordmann said, `if I tape on an IV line. Roll up your sleeve.’
Graves rolled up his sleeve, and Nordmann tied a rubber tourniquet around his arm. He slapped the veins to make them stand out. Then he turned back to the syringe. `I hope I’ve got this mixture right,’ he said. He tapped the bubbles of air out of the syringe.
`So do I,’ Graves said.
Nordmann attached the syringe to a piece of flexible plastic tubing. At the end of the tubing was a needle. `I’ll put the needle into your vein,’ he said, `and tape the syringe to your arm. Just before you enter the room, you can inject the contents.’
Graves felt the coldness of alcohol on his forearm, and then the prick of the. needle.
`Don’t move,’ Nordmann said. `Let me tape it down.’ He removed the tourniquet, applied the tape, and stepped back. `Done.’
Graves looked at the equipment taped to his arm. `You sure this will work?’
`I told you the odds,’ Nordmann said.
Graves stood up. `Okay,’ he said. `Time?’
`Four thirty-nine.’
`Let’s go,’ he said, and ran for the elevator.
They came to the street and ran outside. By his side Nordmann was puffing, red in the face. Graves felt no strain at all; he was tense and full of energy. `Rope,’ he shouted to a cop. `We need rope.’
The cop went off to get some.
`Hurry!’
The cop hurried.
Graves looked at Nordmann. `Listen,’ he said. `I just had a thought. The gas leaked out of the nineteenth floor and killed those two cops. Right?’
`Right.’
`What’s to prevent us from getting knocked off in the elevator as we go up to the twentieth floor?’
`Nothing,’ Nordmann said. `It’s a risk we have to take. If enough gas has leaked back into the building, we may die on our way up.’
`Is that all you have to say?’
Nordmann shrugged. `That’s the situation.’
Two burly cops came over. One had a coil of white nylon rope over his shoulder. `Come with us,’ Graves said. And he ran with Nordmann into the apartment building.
The elevator creaked up slowly. Graves fidgeted. Nordmann seemed very calm. The two cops looked at each other, obviously not understanding what was going on. They stared suspiciously at the syringe taped to Graves’ arm.
They passed the tenth floor.
`Listen,’ Graves said. `I had another thought. ZV is an oil, right?’
`Yes.’
`Well, when I get into that room, all the surfaces will be coated with oil. And deadly. Right?’
`Probably not,’ Nordmann said. `It takes time for the droplets to settle. If the room is cleared of gas fast enough, the surfaces should be safe.’
`You sure?’
`I’m not sure about anything.’
They passed the fifteenth floor. Graves resisted the impulse to hold his breath. He looked at Nordmann. Nordmann crossed his fingers.
Seventeenth floor. Eighteenth floor. Nineteenth floor. Graves waited for the gas to hit him, but nothing happened. They came to the twentieth, and the doors opened.
`We made it,’ he said.
`So far,’ Nordmann said.
They hurried down the corridor.
`Time?’
`Four forty-two,’ one of the cops said.
They came to Apartment 2011, the one directly above Wright’s. The building had been evacuated and the door was locked. The two policemen threw themselves at the door. It didn’t move. They tried again without success.
Nordmann went hurrying down the hallway and returned with a fire axe. He swung once at the door. The axe barely bit into the wood.
`Let me do that,’ one of the cops said, and swung hard near the lock.
`Knock it down, knock it down,’ Graves said.
It took time. There was no easy crash and splintering; the wood was new and strong and thick. Finally the cop managed to bash a hole large enough to admit his hand. He reached in and turned the lock. The door swung open, and they came into an apartment that was all chintz and doilies and heavy furniture.
Graves went directly to the window and flung it open. He looked out and down, feeling the hot, gusty August wind. He was sweating hard.
One of the cops tied the nylon rope around his waist.
`Tell me what I do,’ Graves said to Nordmann, and pointed to the syringe.
`Okay,’ Nordmann said. `You press that syringe to give yourself an injection of the antidote. You can push the plunger this far -‘ he touched the side of the syringe `- and be safe. More than that, and you will suffer effects similar to the gas itself. Clear?’
`Christ,’ Graves said.
The cop cinched the rope tight around his waist.
`Remember,’ Nordmann said, `that you’re counteracting the effects of the gas and you must pay out antidote in relation to your exposure to the toxin. Clear?’
`What happens if I undershoot?’
`That’s worse than overshooting. It’s better to give yourself too much than too little. But not too much too much.’
`When do I begin to inject?’
`Just before your exposure to the gas. If you’re exposed before injecting, you’ll have only five or ten seconds of clear consciousness. So do it before.’
`Four forty-five,’ one of the cops said.
Graves swung one leg over the window ledge.
`You afraid of heights?’ Nordmann asked.
`Terrified,’ Graves said.
`Good luck,’ Nordmann said as Graves crawled completely over the sill and hung there for a moment with his hands.
`We’ve got you,’ one of the cops said.
Graves let go and began his descent down the face of the building.
He tried to balance himself against the stone wall. It was remarkable how dirty the outside of an apartment building could be. His fingers scraped over a crust of dirt and grime and pigeon droppings. He tried not to look down, but once he lost his balance and twisted upside-down, so that he was descending head first. He stared straight at the ground.
The people were minute below him. He was vaguely aware of the hot wind whistling in his ears; it was the only sound he heard. He seemed completely isolated completely alone. He reached for the stones of the apartment wall with tense fingers. He slowly pulled himself around until he was upright again.
His descent continued more slowly. He checked his watch. It was 4:47. Plenty of time, plenty of time . . .
He was now just above Wright’s window. He could see the interior of the apartment clearly – the two tanks, yellow and black, the connecting hoses, the equipment, the snaking cables and electrical lines.
`Okay,’ Nordmann shouted. `Inject yourselfl’
Graves hung dangling and twisting on the rope, nineteen floors above the street, and tried to grab his own forearm. He was clumsy; his breath came in hissing gasps; the rope was tight around his ribs: Finally he got the syringe and pushed the plunger partway down.
`Go!’ Nordmann shouted.
Graves kicked away from the wall, swinging out into space, and came back with his legs stiffly extended. The glass smashed under his feet, and he was swung smoothly, almost easily, into the apartment.
