Pradeep didn’t respond. He was really struggling now, continually losing his footing. Marchant looked at his frame, lean and sinewy, and thought that in other circumstances he would be a natural marathon runner. No doubt that was why he had been chosen. But the mental pressure on Pradeep was sapping every ounce of his energy. Marchant could feel them slowing moments before the GPS beeped.
‘Come on, Pradeep, we’re going to get through this,’ Marchant said, trying to pick up the pace again. They had to keep running until Leila rang. She would have an answer.
‘Two beeps and we’re gone,’ Pradeep replied, suddenly grinning, almost laughing. Marchant realised Pradeep was losing control. ‘You don’t understand, my friend,’ he continued. ‘The American. I can’t leave him.’
‘The Ambassador?’
Marchant looked up at Turner Munroe, who was five yards in front of him. The Ambassador checked his watch, and for the first time Marchant noticed that its bulky design was identical to Pradeep’s.
‘Eight minutes a mile. He always runs the same,’ said Pradeep, suddenly sounding like a trainer admiring one of his charges.
‘Three hours thirty,’ Marchant said. ‘He’s running a 3.30.’
‘One hour forty.’
‘What?’
‘He reaches Tower Bridge after one hour forty minutes.’
‘And?’
Pradeep smiled again, tears welling now. They had been running for one hour thirty minutes. Marchant desperately wanted Leila to ring, more than when they had first tried to split up, more than after their first date at the Fort, MI6’s training centre in Gosport. He looked at the phone in his hand and saw that the commercial networks had been knocked out. Should he try ringing her? The office would be surprised to hear his voice, but she would have told them and they would patch him through to wherever she was. He lifted his head, looked around, and for a moment he thought he saw his father running ahead of him, trundling along at a surprising speed for his age.
He blinked, wiping the sweat away from his eyes, and looked again at the handset. He had to stay on top of this: Pradeep was wearing a belt of explosives linked in some way to the GPS receiver on his wrist. He seemed to be an unwilling participant, rather than a suicide bomber. If he slowed down, the explosives would detonate: ditto if he took any deviation from the marathon course, the waypoints for which had been entered into his GPS. And for some reason it seemed that Pradeep had to stay close to the Ambassador, possibly because of a similar GPS receiver on his wrist.
Suddenly Leila’s TETRA phone was vibrating in his hand. A couple of runners ahead of him glanced around at the sound of the loud ringtone.
‘Leila?’ he said, hearing the panic rise in his own voice. He had to remain calm.
‘Did you try ringing me?’ she asked.
‘No.’
‘Don’t, OK?’ she insisted. ‘Please. Just don’t. There’s some sort of problem with TETRA. Are you still with him?’
‘Yes.’ Marchant glanced across at Pradeep, managed a smile, then pulled back a few yards, out of earshot.
‘Listen very carefully,’ Leila was saying. ‘I’m on the grid at Thames House. MI5 picked up someone in Greenwich and have been sweating him all morning. You’ve got to get the GPS off the Ambassador’s wrist.’
‘Why?’
‘It’s just like you said. The Asian guy’s GPS receiver is linked to his belt using Bluetooth. Only we think the belt can be triggered by Munroe’s GPS too.’
‘If Munroe drops off the pace as well, you mean,’ Marchant said.
‘Yes.’ Marchant thought of Pradeep’s words, how he said he couldn’t leave the Ambassador. ‘And maybe if the link between the two GPSs is broken, if they’re separated,’ Leila added. ‘Technical’s working on the permutations now.’
Marchant could hear other people in the background. He imagined the scene at Thames House, MI5’s headquarters, as news of the situation spread and increasingly senior people arrived, duty officer giving way to Harriet Armstrong, MI5’s Director General, who had helped to hound his father out of office. Leila would be consulted less and less, particularly once his own involvement had become clear. It was a nightmare for MI5: having to rely on someone from MI6, and a discredited case officer, too. It would confirm their worst suspicions about their rivals south of the river. And then the US Secret Service would try to take over, reigniting old turf wars.
‘What about the Americans?’ Marchant asked. ‘Are they running the show now?’
‘Not yet. They wanted to lift Munroe and for us to escort the bomber down a side road, away from the crowds, but the risk of collaterals is too high. We don’t know how quickly the belt might be triggered by removing Munroe.’
‘So I get to wear the Ambassador’s GPS, then what?’
Leila paused. ‘You both keep running while Cheltenham tries to intercept the satellite signals.’
‘Tries?’
‘They’re keen to pull you out, Daniel, put someone else in.’
‘I bet they are.’
‘But it’s going to take time, and we haven’t got any.’
‘Pradeep’s knackered.’
‘I know. We’ve got a feed from the BBC helicopter above you now.’
Marchant had forgotten about it, hovering high above him. So Armstrong could see them, he thought. He could never forgive what she and others in MI5 had done to his father. Stephen Marchant was a man who had lived and breathed for the Service, only to be accused, at the pinnacle of his career, of the very thing he had always despised in others. Some people died of a broken heart; his father had died of shame, within weeks of being forced to retire as Chief. There was nothing more important to his father than loyalty. Even the best assets he had recruited, the ones who made his reputation in Delhi, Moscow, Washington, Paris, had filled him with a deep loathing for mankind and its willingness to betray.
‘Don’t Munroe’s babysitters have a radio link?’ Marchant asked. Things might become easier for him and Leila after this; the family’s reputation might be restored; he might get his old job back.
‘They’re linked to each other,’ Leila replied, ‘not to the outside world.’
‘That figures. Is there a code for this yet? Something to reassure the Ambassador I’m not from Albania when I relieve him of his watch.’
‘Tell them it’s a Defcon Five. Try “Operation Kratos” if that doesn’t work. Once you’ve got the GPS, persuade Munroe to leave the course as soon as possible. He must be out of there before Tower Bridge.’
‘What is it with the bridge?’ Marchant asked, remembering Pradeep’s words.
‘It’s where the biggest crowds are, apart from the finish. We’re trying to clear the area now. Bomb disposal are on the way. We’ve got blues assembling in all the back streets, from you to Tower Bridge.’
The line suddenly dropped. There was not much more to say. Marchant moved up to join Pradeep again.
He had some jelly beans on board for the final few miles, but he decided to pull the bag out from his pocket now and offer them to Pradeep, who visibly rallied at the sight of them.
‘Beats the gels,’ Marchant said, taking a couple himself after Pradeep had grabbed a desperate handful. ‘I’m going to talk to the Ambassador, then I’m coming back,’ Marchant said. ‘It’s
