It was him, Bolt was sure of it. He wiped his eyes, spat on the ground to get the taste of gas out of his mouth and kept ru

Thirty-five, thirty, twenty-five, twenty yards. His footfalls sounded artificially loud on the tarmac. Two uniformed cops in full riot gear stood in the road surveying the crowd uneasily, their batons drawn. One of them heard Bolt's rapid approach and, as if he was looking for someone to lash out at, lifted his baton menacingly and shouted at him to stop. Bolt didn't even slow down. He just pulled out his warrant card and yelled 'Police!' as loud as he could, and miraculously the cop simply got out of the way.

Unfortunately, the suspect also turned round. The expression on his face was one of pure shock, even behind the black shades, and in that single moment Bolt knew he was looking at the right man.

The suspect took off down the street, knocking over a middle-aged woman in his haste and stumbling before regaining his balance. Her husband shouted something and threw out a hand to grab him but he was nowhere near quick enough. This guy was speedy, and he had one hell of a lot of incentive to get away from his pursuers.

Bolt was less fit than he should have been. These days he only got to the gym once a week at best, and he was begi

Bolt sneaked a quick look over his shoulder. Two of the team, Dan Blakeley and Cliff Yakonos, were ru

'Suspect two ru

'This is control. Back-up on way. ETA one minute.'

Without warning, a large man in his thirties, with a kid of about ten who must have been his son, jumped at the suspect as he ran past, trying to grab him in a bear hug. It was a brave move. Brave, public-spirited and totally rash. He got a grip, knocked the suspect against the window of a charity shop, but wasn't quick enough to neutralize the knife. The suspect reacted ruthlessly and instinctively, driving it directly into the man's upper body with a single bloody lunge, his face contorted with rage and desperation. The man went down like a falling tree, probably dead before he hit the ground. His kid cried out, 'Dad!' It was a terrified, shocked howl, a sound that would live with Bolt for a long time. It was a savage reminder that death can be so quick. One second you're a living, breathing, smiling human being out with your boy to see your team play football on a glorious evening, the next you're gone. For ever.

'Suspect two has stabbed member of public; urgent medical assistance required,' Bolt yelled into his mike, but it wasn't urgent. The guy was dead. Like Andrea's cleaner and Jimmy Galante. Maybe even Emma. Laid low by a killer without the slightest regard for human life.

A fury filled Bolt. It was stronger than any he'd felt in a long, long time, maybe ever, dwarfing the emotion that had soared through him as he kicked and beat Marcus Richardson, and it seemed to give him a blind, terrible energy.

The man's intervention might have cost him his life but it also cost the suspect five or six yards. He took off again as soon as he could, waving his bloody knife as he ran past the son he'd just deprived of a father, but he now had only a handful of yards on Bolt. A junction was coming up ahead, and when he reached it he turned hard right, his body almost jack-knifing in his bid to keep momentum. Bolt kept coming, not even thinking about hesitating as he too took the corner, even though he knew the suspect could use the blind spot as an ambush point. He was moving beyond logical risk assessment and into the realms of pure revenge. He was going to beat the information he needed out of this bastard, would kill him if he had to, but there was no way he was losing him. No way at all. It was an incredibly liberating thought.

When he rounded the bend, the suspect had gained a few yards and was racing across to the other side of the road through the blocked traffic. There were fewer people milling about on the pavements here, and no sign of any police either. But also less cover for his quarry, and Bolt knew that as long as he kept pace, feeding the suspect's position into the mike, then he wasn't going to get away.

After thirty more yards, the suspect looked round and saw Bolt still right behind him. He turned back and kept ru

The suspect turned a hard left. Bolt did the same, shouting the street name into the mike, but he wasn't looking where he was going properly and he slipped and lost his balance, jarring his knee as he hit the deck hard, and rolling on to his side. He ignored the pain, jumped up and kept ru

The street led up to the entrance to a high-rise council estate. It was a dead end for cars. Bolt cursed. He knew that if the suspect got inside the warren of alleys that these characterless sixties estates always featured it would mean he'd almost certainly slip through the net. Jesus, where the hell was the back-up? Even the helicopter was no longer overhead; doubtless it had been sent to chase the money. It disgusted him that the recovery of the half a million pounds was more important to his bosses, and their bosses, than capturing a brutal knife-wielding killer and possibly saving the life of a fourteen-year-old girl, but then in his heart he'd always known it would be. The whole British justice system was built on the protection of property above the protection of lives, which was why armed robbers were always put away for two, three, sometimes even five times as long as child molesters.

Bastards. In those taut, desperate seconds, Bolt was a man entirely on his own, out on a limb and having to do everything himself, knowing that failure was unthinkable.

The armed response vehicle seemed to materialize from nowhere. In fact it had come out of a side road up ahead, just in front of the entrance to the estate. It stopped dead, blocking the way, and the three officers were out in an instant, their MP5s pointed straight at the suspect, who was twenty yards from them.

'Armed police! Drop your weapon!'

Bolt reached into his pocket for the pepper spray, knowing that the suspect was going to turn and run back his way, away from the guns, meaning it would be up to him to make an arrest.

But the suspect didn't. He kept on going. Charging right at them, yelling something that sounded remarkably like a battle cry.
