‘You chose your words carefully,’ said Shepherd, ‘but I got the implication.’
‘Remember when we first met, in the Special Forces Club in Knightsbridge? I ran a moral dilemma past you.’
‘Sure. Would I kill a terrorist who was on his way to kill civilians but who wasn’t a threat at the time?’
‘Yeah, well, let me give you another. Some scientist in the States has been using it as part of an experiment to see how the brain reacts while it’s making moral decisions.’
Shepherd sighed. ‘If you must.’
Yokely ignored the sarcasm. ‘Say you’re standing by a railway line and a runaway wagon’s racing towards you. You’re beside a set of points. If the wagon carries on the way it’s going, it’ll hit six people on the line. They’ll die unless you do something. If you pull the lever that controls the points you can divert the wagon along another line. But there’s a man on the second line. He’ll die if you change the direction of the runaway wagon. What do you do?’
‘That’s a no-brainer,’ said Shepherd. ‘You pull the lever. Six lives are more important than one.’
‘And ninety-nine per cent of the population would agree with you,’ said Yokely. ‘Now, say you’re standing on a bridge over the line and there’s a runaway wagon heading towards six people. No points this time, but you could throw yourself off the bridge in front of the wagon. Problem is, you’re not big enough to stop the wagon. But standing next to you is a fat guy. More than enough body mass to stop the wagon. Do you throw him off the bridge in front of the wagon to save the lives of the six people on the line?’
Shepherd smiled. ‘I get it,’ he said.
‘It’s a tougher call,isn’t it? Yet the premise is the same. You perform an action that puts six lives ahead of one. But while most people would pull the lever without hesitation, most would not push the guy off the bridge. Why do think that is?’
‘Because most people can’t kill up close and personal. Pulling a lever detaches you from the killing, I guess.’
‘The physical contact, you mean?’Yokely’s brow furrowed. ‘Maybe that’s it. But you’ve never had a problem with that, have you?’
‘I don’t lose sleep over the people I’ve killed,’ said Shepherd. ‘But every time I’ve taken a life, I’ve had right on my side. A moral and legal right. And, more often than not, the people I’ve killed have been trying to kill me.’
‘Sure, that makes the dilemma simpler, doesn’t it? If you’re the one standing in the way of the runaway wagon, you’ll do whatever it takes. It’s when you’re on the bridge that your moral code kicks in. But Hassan Salih is a stone-cold killer. If we don’t stop him he’ll kill Charlotte Button, maybe taking out her family as well. And he’ll carry on killing because that’s what he does for a living.’
‘I’m losing your metaphor. Is Salih the guy on the bridge or the runaway wagon?’
‘He’s the piece of shit that tried to kill your boy and who’s going to kill your boss unless we do something to stop him.’
‘You say “we” but you mean me, don’t you?’
‘She’s your boss,and it’s your country,’said Yokely. ‘I can’t go around killing people on your turf. It’s only the Russians who do that.’
‘So what are we talking about here, Richard? Are we talking about protecting Charlie, or about protecting you?’
Yokely smiled. ‘Tomato, potato,’ he said.
Shepherd drove from Belfast airport to Dublin and caught the Stena Line high-speed catamaran to Holyhead. The sea was mirror flat and the crossing took less than two hours. As he drove off the ferry he used his hands-free to call Martin O’Brien. O’Brien sounded out of breath. ‘You’re not having sex, are you, Martin?’ he asked.
‘Chance’d be a fine thing,’said O’Brien. ‘Just done a twelve-mile run.’
‘How fast?’
‘Just over the hour,’ said O’Brien.
‘Well done you.’
‘And I’ve lost three kilos in the last week.’
‘Kudos.’
‘Mind you, I’d kill for a burger. What’s up?’
A Porsche drove past Shepherd at breakneck speed. The driver was barely out of his twenties with a mobile phone pressed to his ear. Shepherd’s natural competitiveness kicked in and he had to fight the urge to stamp on his accelerator and give chase. ‘How’s it going with Charlotte?’
‘Bloody hard work,’ said O’Brien. ‘I’ve got four guys in rotation but she’s as slippery as an eel.’
‘Yeah, I told you she was shit hot at surveillance.’
‘You weren’t wrong. But we haven’t shown out and we haven’t seen anyone else on her tail.’
‘Have you spoken to the Bradford boys?’
‘Yeah, they said you had a spot of bother in Hereford.’
‘They handled it just fine.’
‘So, all’s well that ends well, as my old gran used to say.’
‘I’m not sure about that, Martin,’ said Shepherd. ‘The guy who went to my house didn’t fit the profile of a professional hitman. A bit young.’
‘So there’s more than one?’
‘I don’t know for sure, but I’m assuming so. I’m going to pick up a weapon from the major, just in case. And I’d like you to keep an eye on Charlie for a bit longer.’
‘Pleasure,’ said O’Brien.
Shepherd ended the call, then rang Caroline Stockmann and explained that he was back in England for two days. ‘We can meet tomorrow evening, say six o’clock,’ said the psychologist. ‘How about the Stag?’
‘In Hereford?’ said Shepherd, surprised. He had assumed she’d want to see him in London.
‘Mountains, Muhammad, and all that jazz,’ she said. ‘You’re a busy man and I get a very generous allowance from SOCA.’
‘Six it is,’ said Shepherd. ‘Inshallah.’
‘Indeed,’ said Stockmann. ‘God willing.’
It was late at night when Shepherd arrived at his house in Hereford. He parked the Audi in the street and let himself in. As he flicked on the light one of the Bradfords put away his gun and grinned. ‘Sorry,’ he said. ‘Didn’t hear you drive up.’
‘Hey, my fault for not calling first,’ said Shepherd. ‘And I’m sorry – normally I’m good with faces but I can’t tell you guys apart.’
‘I’m Billy, the good-looking one.’
Shepherd grinned. ‘Everyone asleep?’
‘They went up at nine,’ said Billy. ‘Jack’s coming at midnight. I was making a coffee. Do you want one?’
‘Thanks,’ said Shepherd. He went upstairs to his son’s room. Liam was asleep, hugging a pillow. Shepherd knelt beside the bed and brushed the boy’s hair away from his eyes. Liam muttered something but didn’t wake. Shepherd kissed his forehead. ‘Sweet dreams,’ he whispered.
He went downstairs. Billy had made the coffee and handed him a mug. ‘Everything okay?’ Shepherd asked.
‘No problems,’ said Billy.
‘Katra and Liam have no idea what went down?’
‘Slept through it all. I’ll show you the damage.’ He took Shepherd to the sitting room and showed him the small hole in the sofa. ‘Bullet’s still in there,’ he said. ‘Probably lodged in the frame. I think you can leave it where it is.’ He went to the wall by the fireplace. ‘This one’s a bit more complicated,’ he said. There was a picture on the wall, a pen-and-ink drawing of the clock tower at the old Stirling Lines barracks. Engraved on it were the names of SAS members who had died in action. He moved the picture to reveal a hole that had been gouged in the wall. ‘We dug out the bullet and moved the hook a few inches to the left so that the picture covers the hole but you’ll have to get it patched up,’ said Billy.
‘I’ll decorate the room as soon as I have a chance,’ said Shepherd.
Billy put the picture back and sat in an armchair.
‘The guy who came here, Tariq?’
‘Tariq Chadhar,’ said Billy.
‘What sort of gun did he have?’
‘Glock 17 with a silencer.’
‘A professional rig,’ said Shepherd. ‘Did he seem like a pro to you?’
‘Definitely not,’ said Billy. ‘Nervous as shit, slow reactions, damn near pissed himself. Is there a problem?’
‘I don’t know,’ said Shepherd. ‘I was warned there was a pro around, a pro who knew where I lived. But the guy you dealt with doesn’t fit the profile.’
