Simon Kernick - Target

Canaver was a solid career copper, only one year short of his thirty years' service, and he liked to do things methodically and by the book, because he knew that, ultimately, that was the best way. In all his time in the police he'd never had to make a life-or-death decision, and he was truly hoping that this wasn't going to change now. As well as a fleet of ambulances, Canaver had some forty officers on the scene, a dozen of whom were armed. As he'd already announced to the building's occupants on the megaphone several times in the last ten minutes, he had the place surrounded. Neither the hostage negotiation team nor the big guns from Counter Terrorism Command and SOCA were yet at the scene, but the sooner they were, the happier he'd be. In the meantime he'd carry on repeating his request every three minutes for whoever was inside to give him or herself up. So far he'd received absolutely no response, although there were several lights on inside, so he and his people continued to stand silently in the pouring rain using a line of squad cars as cover, waiting to be relieved.

Behind him he heard several of the other officers whispering urgently to one another. The explosion had made everyone jumpy. Luckily, none of them knew its ramifications. The only people within the Essex police force who'd been informed that the lorry was carrying poison gas were the chief constable, his assistant, and Canaver himself.

Canaver fingered his mobile phone nervously, wondering if he was going to get a call to evacuate. As well as terrorists, he'd been told that the building might also contain a kidnap victim, although whether she was alive or not was still unclear. There was definitely someone alive inside though: two of his officers had seen movement in one of the upstairs windows a few minutes earlier. He didn't like the idea of abandoning a potential victim of crime, or letting the criminals holding her get away, but he had to admit that he'd be more than happy to leave this scene and its heavy responsibilities behind.

'I didn't expect an evening like this when I came on duty today,' said DCI Nigel Teasdale, the head of Essex CID and a colleague of Canaver's for more than ten years now.

The two men had never got along particularly well. Teasdale was brash, impulsive, and far too gung-ho – a trait that was definitely not needed in a siege situation – but right now it was all hands on deck and Canaver had no choice but to work with him.

'I don't think any of us did,' answered Canaver, wondering how Teasdale would react if he was told what the lorry contained. For all his bravado, the fat sod would probably run a mile, which given the size of his gut would be a sight worth seeing.

The thought momentarily cheered Canaver, but only momentarily, because as he stared straight ahead at the barn he saw smoke beginning to seep out of one of the windows on the upper floor, and the first flickering glow of flames coming from inside.

Others saw it too, including Teasdale. 'Blimey, he's burning the place down,' he announced loudly in a statement of the blindingly obvious. Then he asked the question Canaver had been dreading: 'What the hell do we do now?'

In the same moment, the head of the armed response team, Sergeant Tony Lennis, appeared at Canaver's other side. 'Do you want us to go in?' he asked.

The truth was that Canaver had no plan of action, no idea of the numbers he was up against or how well they were armed. Even the blueprints for the building hadn't arrived yet. Lennis might have been a firearms officer for close to two decades, but he'd never fired a shot in anger, and if he messed things up now it would be Canaver's responsibility.

The two men were looking at him expectantly. In the skies above, a helicopter circled noisily. Smoke was pouring out now, the flames rising higher. He could call the chief constable, put the onus on him, but that might look like indecisiveness, and time was running out. There could be someone in there in huge danger.

Christ, how he hated being put in this position.

He turned to Lennis, saw the pent-up tension in the man's face, the way he was bouncing up and down on the balls of his feet. 'All right,' he said, the words coming out with difficulty. 'Go in.'

As one armed officer yanked open the left-hand barn door, Tony Lennis, breathing apparatus on, moved swiftly inside, his Heckler and Koch MP5 submachine gun held out in front of him, followed immediately by two of his most experienced officers. Although the lights had been turned off on the ground floor, powerful spotlights from outside were shining through the two narrow windows at the front, illuminating the smoky interior enough for Lennis to spot the corpse of a tall skinny guy in the middle of the stone floor. He had intelligence that there might be a twenty-nine-year-old IC1 female being held captive somewhere in here, but he couldn't see her and had little desire to go upstairs where the fire had clearly been started, in case he got trapped.

A bullet hissed past his head, and one of his people – Jim Walton, a recently divorced father of three kids under ten – went down with a muffled yelp. Another round flew past, narrowly missing Lennis again, and he realized that in twenty years of armed service this was the first time he'd ever been fired at with live ammunition; and worse still, whoever was firing was good.

The shots were coming from behind a partly open door straight ahead, but neither the assailant nor his gun was visible.

To his credit, Lennis didn't hesitate. Nor did his other colleague, recently married Terry 'One Shot' Landesman. They both opened up with the MP5s, the bullets knocking open the door with a loud crack.

A shadow moved beyond it and Lennis let off another burst of fire, the torch beam from his MP5 lighting up the gloom. Where the fuck was he?

'Officer down!' he shouted into his mouthpiece as more officers poured in through the barn door. 'Repeat, officer down! We need urgent medical assistance!'

Lennis knew he had very little time. Ordinarily he would have secured the ground floor then waited while his superiors attempted further negotiation, but the fire was spreading fast above them and it wouldn't be much longer before the wooden ceiling gave way, condemning them all to a fiery grave.

With his heart hammering in his chest, he advanced on the open door, Landesman by his side. Lennis went through first, pointing his weapon up the wooden staircase that led to the next floor. The smoke was everywhere here and he could hardly see a thing.

Then another bullet hit the wall just behind him, and he returned fire, the sound of the discharge making his ears ring.

A shadow flitted across the balcony and Lennis fired again, moving his weapon in a tight arc, his rounds tearing up the woodwork. He thought he heard a scream and saw a figure stumble as if he'd been hit, but visibility could be measured in feet and it was impossible to tell for sure. He became aware of Canaver calling out on the megaphone for the man to surrender, but his voice was stifled by the crackle of the fire and the sound of his own breathing.

With a nod to Landesman, he raced up the stairs, eager to press his advantage, operating on instinct now, not thinking of the dangers inherent in his actions. As he reached the top, the smoke seemed to swallow him up, and he felt the heat of the fire against his protective overalls. He turned the corner, finger tensed on the MP5's trigger, and almost tripped over the body of the gunman at his feet. He'd been shot in the head, the pistol with silencer still in his hand. It was hard to tell whether he was dead or not, but he was definitely in a bad way.

But it was the sight of the girl in handcuffs lying on the floor a few feet away through an open door that grabbed Lennis's attention. Her face was smoke-blackened and she was choking beneath her gag, eyes tight shut in an effort to keep out the smoke.
