Then he noticed what looked like an oversized watch on the man’s wrist. Leila had something similar for long runs. It was a basic GPS receiver, relaying her position, speed and when she should speed up or slow down. (He remembered how she had once said it beeped ruthlessly at her when her pace dropped below a pre-programmed speed.) It wasn’t as sophisticated as the military units he and other case officers had been issued with in Africa, but it wasn’t a toy either.
‘What’s happening?’ Leila said, appearing on his shoulder. ‘We were going so well.’
Marchant nodded at the man in front and slowed up a little, falling away from the group.
‘See the guy with the belt,’ he said, as they both slowed to their former pace. Marchant was short of breath as he continued. ‘I don’t think those cartons are for drinking.’
‘Why not?’ Leila asked.
‘And that man up there, the tall one all in white. Isn’t he the US Ambassador?’
‘Turner Munroe? Dan, what’s going on?’
Marchant knew what Leila was thinking. He was deluded, still drunk from the night before, seeing things where there was nothing to see. He’d watched it himself in other case officers who had been called in from the field and tethered to a desk in Legoland (the name employees had given to MI6’s headquarters in Vauxhall), drinking themselves to death to alleviate the boredom of captivity. In his case, though, he didn’t even have a desk. That was the hardest part: knowing there might never be a way back. And now here he was, hard on the heels of a runner in the London Marathon, convinced that the man was shortly to kill himself and everyone around him, including the US Ambassador to Britain. He’d run agents who were less paranoid.
‘What exactly did Cheltenham pick up last night?’ Marchant asked, breathlessly.
‘Nothing like this.’ He guessed Leila was already making her own calculations, weighing up risks. ‘How can you be so sure about the belt?’
‘By asking him,’ Marchant replied.
‘Don’t be stupid, Dan.’
‘For a drink.’
‘Dan…’
Marchant ignored her and moved towards the runner again, pulling up alongside. The man was clearly in trouble. Sweat was pouring off him as his head bobbed like a donkey’s.
‘Hot one,’ Marchant said. The man glanced at him nervously and looked ahead again, wiping his thick eyebrows with the back of his hand. ‘Did you see that last drinks station?’ Marchant continued. ‘Crazy. Shouldn’t have to queue for water, not on a day like this.’ Marchant smiled at the man, nodding towards his belt. Inside, his stomach turned. He was right. ‘Couldn’t have one of yours, could I?’
‘Who are you?’ the man said aggressively. His accent was thick, from India: another cell from the subcontinent. Marchant knew immediately there would be consequences, for him, for his father, but they would have to wait.
‘No problem. Any idea who that is?’ Marchant gestured at the US Ambassador. ‘Brought his own fan club with him.’
‘Please, stay away,’ the man said.
The two of them ran on in silence. Marchant’s mind was racing. Post 7/7, it was bulky clothing that had attracted attention. Here was a man wearing explosives on the outside, and it was so bloody bold no one had noticed. The pouches must be wired together inside the belt, he thought. But if the man was a running bomb, why hadn’t he blown himself up by now? Why was he warning him to stay away? And if his target was the Ambassador, he could easily have bunched in close to him and his babysitters and taken them all out before now.
He remembered the last suicide bomber he had seen, in Mogadishu. They had been talking in the marketplace, making nervous progress. Then a phone rang. Twice. Marchant had run for his life. The man’s head was found on the corrugated-iron roof of a nearby café. The bomber hadn’t wanted to die, Marchant was sure of that. Afterwards, in the British Embassy bar, as his hand shook the Johnnie Walker out of his glass, he kept telling himself, over and over, that the bomber had not wanted to die. It had made it easier to understand. The handler knew it too, which is why he had detonated the bomb himself.
This time, he had to keep his man talking, establish the method of detonation, hope the mobile networks would be too busy for a phone call from a third party. Like the bomber in Mogadishu, this man was also not a volunteer. He had been forced to wear the belt. It was happening more and more these days: genuine suicide bombers were becoming hard to find. Trust your gut feeling, his father had said.
‘That watch you’ve got there,’ Marchant said. ‘GPS?’
‘Sat-Runner,’ the man replied. Better, Marchant thought, much better; a gear and gadgets man.
‘Useful piece of kit.’
The man nodded. Then the GPS beeped. Both of them looked at it. ‘Please, you must go,’ the man said to Marchant. They weren’t the words of a suicide bomber hoping to take as many people with him as he could.
‘Why’s it beeping?’ Marchant asked, recalculating the risk to himself, to others. His lungs tightened, making words difficult. ‘Does it do that when you slow down, when your pace drops?’ he asked, trying to remember how Leila had explained it, cursing himself for not showing more interest at the time.
The man nodded. He had been coerced into this, Marchant repeated to himself, which meant that he could be talked out of it.
‘Then what?’ Marchant glanced down at the belt again.
‘Can you help me?’ They looked at each other for a moment, gauging the fear in each other’s eyes.
‘I can try. What’s your name?’
‘Pradeep.’
‘Keep it going, Pradeep. You’re doing fine. Just fine. Don’t go anywhere. I’m coming straight back.’
Pradeep glanced over his shoulder, stumbling again, as Marchant dropped back down the field to search for Leila, but he couldn’t see her in the crowd. How much faster than her had he been running? He slowed up some more, looking at everyone who overtook him. He shouldn’t have left her, he knew that now. There were too many people, too much noise.
Above him the helicopters circled low again, drowning out the jazz band playing on the roof of a pub. Children by the roadside cheered, holding out bags of sweets. Stout women from St John’s Ambulance were offering outstretched hands of Vaseline. And then he spotted her, over on the far side of the road, hidden behind a small group of club runners. He cut across the flow of people to join her, almost tripping on the heels of another runner. His legs were tiring, more than they should have been at this stage of the race. He was desperate for more water, too.
‘Leila, we’ve got a problem,’ he said, short of breath. ‘A big problem.’
‘Where have you been? I couldn’t see you anywhere.’
In between swigs from her drinking bottle, he told her about the GPS, and how he thought it was linked in some way to the pouches around Pradeep’s waist, which he was now convinced contained explosives–enough to kill dozens of people if he was in a tightly bunched group. He knew how he sounded: a has-been desperate to prove himself in the field.
‘My guess is, if he drops below a certain pace, the isotonics will blow,’ he added.
‘Daniel…’
Leila’s face told him she was struggling to comprehend the situation, trying to decide whether his reading of it was deluded or credible. She was momentarily tearful.
‘You’ve got to leave this to others,’
