more. Okay, assemble them. Smith out.' He glanced back at the two DEA agents. 'Right. Any other suggestions?'
Mike took a deep breath. 'Is he still valuable to us, if we can get him back?'
'Possibly.' Smith stared at him. 'Your call, son.'
Time stood still. 'I need to work on my grammar,' Mike said slowly. 'But of course, after CLEANSWEEP we'll have more subjects to work with.'
Smith held out his hand for the walkie-talkie, watching Mike's face as he spoke: 'Sergeant? Change of plan. Hold the floor sweep, I don't think we've got enough people to risk it, if the target manages to arm himself… Instead I want you to stand by to execute code BLUEBEARD. That's BLUEBEARD. I'm going to make an announcement in a couple of minutes. If the fugitive doesn't give himself up, we'll execute BLUEBEARD, then ventilate and search the place afterward.'
Pete looked shocked. Mike elbowed the younger agent in the ribs to get his attention. 'Go get us all respirators,' he said. Smith nodded at him. 'You really going to do it, sir?'
Smith nodded again. 'We need to test the security system, anyway.'
'Ri-ight.' The desk guard was watching nervously, as if the colonel had sprouted a second head. Mike grimaced. 'I love the smell of nerve gas in the morning.' Pete reappeared and handed over a sealed polythene pack containing a respirator mask and a preloaded antidote syringe.
'It's not nerve gas, it's fentanyl,' Smith corrected him. 'Where's the PA mike on this level?' he asked the desk guard.
'Fentanyl is a controlled substance,' said Pete, a conditioned reflex kicking in.
Mike looked round edgily. BLUEBEARD was a last-ditch antiterrorist defense; on command, compressed gas cylinders plugged into the air-conditioning on each floor would pump a narcotic mist throughout the building. Sure, there was an antidote, and the ventilator masks ought to stop it dead, but the only time it had ever been used for this purpose-in Russia, when a bunch of Chechen terrorists had taken a theater crowd hostage-more than a fifth of the bystanders had been killed. Gas and confined spaces did not mix well.
'Relax, boys.' Smith looked bored, if anything. 'If you're thinking about that Russian thing, forget it-they didn't have respirator masks there. You're perfectly safe.' He pulled the gooseneck PA mike toward his mouth and hit the red button. 'Is this thing-yes, it's live.' His voice rumbled through the corridors and floor, amplified through hidden speakers. 'Matt, I know you're in here. You've got five minutes to surrender. If you want to live, come out from wherever you're hiding, and go to the nearest elevator bank. Hit the button for the tenth floor, then lie down on the floor of the elevator car with your hands on your head. This is your only warning.'
He killed the PA and turned to the walkie-talkie: 'Okay, you heard me, Sergeant. Fifteen minutes from my mark, I want you to execute BLUEBEARD on all floors above ten. You've got ten minutes from right now to do a cross- check on all personnel and make sure they're ready. Antidote kits out, boys. Over.'
Smith unsealed his respirator kit. 'What are you waiting for?'
'The broken window on the twenty-third,' Mike said slowly. 'Has it been repaired? And has anyone secured the window-cleaning system?' He opened the packaging around his respirator as he spoke, peeling the polythene wrapper away and yanking the red seal tab to activate the filter cartridge.
'The-' Pete's eyes narrowed.
'We've agreed Matt's not stupid. He probably guessed we'd have something like BLUEBEARD. Maybe he broke the window because he wanted fresh air to breathe?' Mike pointed toward the nearest outside wall. 'That got me thinking. Someone's got to clean the windows, haven't they? That means a motorized basket, right? Maybe he figured he could ride it down past the security zone while we're busy trying not to choke ourselves?'
'Point.' Smith began to reach for the walkie-talkie again.
'How about Pete and I check out floor twenty-three?' Mike asked, pulling the mask over his head. 'We've got respirators, we're armed, we can take a walkie-talkie. More to the point, maybe we can talk him down. Is that okay by you?'
Smith thought for a moment. Finally he nodded. 'Okay, you have my approval. Stick together, don't take any risks, and remember-I'm not going to cancel BLUEBEARD if he gets the drop on you. Especially not if he takes one of you hostage. Understood?'
'Yes.' Mike glanced at Pete, who nodded.
Smith gestured at the charging station by the security desk: 'Take one of these, they're fully charged.' He picked up his own walkie-talkie. 'Sergeant, I want you to check out the janitorial facilities, find out how they clean the windows above the tenth floor. If there's an outside winch, I want it secured.'
Mike headed for the central service core, opening his holster. 'Come on,' he told Pete, his voice muffled by the mask.
'What's the plan?'
'I want to check out the floor tiles where he smashed the window. Where is it?'
'Twenty-third floor. You turn left at the checkpoint, then take the first transverse corridor past the service core. You want to follow me?'
'He's not armed, is he?'
'I don't think so.' Pete sounded uncertain.
'Well, then.' Mike held his gun at his side and gestured at the door onto the fire stairs with his free hand. 'Let's go.'
They took the steps fast. Mike rapidly discovered that breathing through a gas mask was hard work. He paused, gasping for air, on the twenty-second-floor landing, leaning against a brace of drab green pipes running up and down. Pete seemed to be doing fine: There's no justice, he thought. 'Shit. I can't run in this thing.' I'm too old for this SWAT-team game. I'm not thirty-six yet, and I can't run up flights of stairs in a gas mask anymore. What's wrong with me? He pulled his mask off and shoved it into the inside pocket of his jacket.
'You sure it's safe to do that?' asked Pete. Mike noticed that he wasn't wearing his mask, either.
'I'll hear when Smith trips the gas tanks,' he said with a confidence he didn't feel. 'Anyway, make sure you've got yours, right? Okay, here's how we'll do it when we come out of the stairwell. I'll go first, covering the floor. You follow me, covering the ceiling and my back. We head for the window, and if he's not there, we head for the security station and the PA mike for this floor and I try talking to him. What's wrong with this picture?'
Pete shook his head. 'Nothing obvious to me.'
'Okay, let's go.' Mike shoved himself back onto the stairs and took the last two flights, paused to catch his breath just inside the door, then pushed through.
The twenty-third floor was eerily deserted, a high-altitude Mary Celeste. Beige carpet tiles, slightly scuffed and in need of cleaning, floored corridors where doors stood open on unfurnished office suites. The black bubbles of surveillance cameras sprouted from ceiling tiles, some of them discolored by water seepage. One of the reasons floor twenty-three had been left
vacant was that it had needed more refitting than the rest of the building, thanks to a burst pipe the previous winter. Some of the lighting panels flickered erratically. Mike headed up the corridor, cautiously checking side doors opening off it for any sign of human presence. Just because we don't think he's armed doesn't mean he isn't, he told himself, whenever he felt self-conscious.
He turned the corner onto the last stretch of passageway. There was no door at the end, just a wide open-plan office space, almost a thousand square feet of it, walled in windows. Abandoned desks and shelving units clustered in forlorn huddles around the floor. He could hear something now, the whistle of wind blowing past an empty gap in the glass side of the building. It was slightly chilly, even though it was a hot day down below. Mike paused just outside the door and glanced over his shoulder at Pete, who was staring tensely at the ceiling behind them. 'Going in.'
'Okay.'
Mike ducked through the entrance and spun round. Anticlimax: nobody was lurking in the corners behind him. But what about the desks-he crouched, casting his gaze around at ankle level. No, there were no giveaway legs visible under the furniture. Nothing, no sign that anybody had visited the place.
'He's not here?'
'Hush.' Mike backed toward the wall beside the door. 'Keep me covered from right there.' He slid along the wall, around the edge of the room. Three minutes left, he thought. What if-
There was nobody behind any of the furniture. None of the ceiling or floor tiles had been disturbed. The room
