Ben took the Zeiss glasses away from his eyes, and the house was suddenly tiny and white in the distance. Letting the binoculars hang from his neck, he lay prone on his branch for a few minutes, thinking hard.

He thought back to all the places he’d raided alone. He was good at what he did, and he knew it. But to go up against something this size was a suicide mission, not just for him but for the kid. It couldn’t be done. There was no use. He had no choice but to go after Philippe Aragon and give him to Kroll.

He backed along the branch and started climbing downwards, agile and silent. He reached the ground, wiped his hands and made his way towards the road, lighting a cigarette as he walked to the nondescript grey van, shoulders hunched against the biting wind. He sighed as he opened the van door and slid into the driver’s seat. He laid the Zeiss glasses on the seat next to him, leaned back behind the wheel and finished his cigarette. Then he crushed the stub into the ashtray and twisted the ignition. The diesel rasped into life.

It was a long drive to Brussels. He’d better get moving. But before that, he had one other stop to make.

Chapter Fifty-One

Philippe Aragon s residence near Brussels

That evening

It was late, and the two private bodyguards were sitting relaxed in armchairs at opposite ends of the large open-plan main reception area. They had nothing to do but leaf through back-issues of The Economist, astronomy magazines and architecture books while their charge came and went, filled out paperwork and made phone calls.

They weren’t complaining. Their two colleagues were out in the freezing cold patrolling the grounds, while they stayed inside the comfortable building soaking up the warmth from the solar heating system. In two more hours they’d have to put on their coats and exchange places with them, and they weren’t looking forward to that.

Philippe Aragon was feeling mentally drained after working all day. He had four major addresses to prepare, and stacks of files and reports to sift through. His PA, Adrien Lacan, had left him a whole pile of letters to check and sign, and that alone had taken up a big piece of his day. He prepared a cup of organic cocoa with a pinch of cinnamon powder, said goodnight to the two bodyguards, and headed up the spiral staircase to his private quarters at the top of the house, carrying the steaming mug.

The electronic security system sealed him inside the reinforced door. He kicked off his shoes and slipped his feet into a pair of soft slippers, then walked through his private sitting room. Here at last he felt as though he was in his own tranquil space. He tried to forget about the armed men who were watching over him, sitting in his home and walking about his garden. The place was beginning to feel more and more like a fortress. It was mostly down to Colette’s insistence. Ever since the chalet episode she’d been edgy about safety. Maybe she was right, but it was tough living like this, looking over your shoulder all the time. He knew it was stressful for her as well, and he was glad that she’d been able to have a break and get over to Florida for her cousin’s wedding.

He pottered around his sitting room, sipping his cocoa, feeling mentally tired but restless. He sifted through a rack of CDs and slid out the Mischa Maisky recording of Bach’s suites for solo cello. The warm, woody tones of the cello breathed through the speakers and soothed him. He sat in a soft armchair and closed his eyes, listening to the music and tapping gently with his fingers against the armrests. But Philippe wasn’t a man who could switch off his active mind that easily. He jumped up. For a moment he thought about going into his private study next door, firing up the computer and checking to see if Colette might have emailed him from the States. But he knew that once he was sitting behind the keyboard he’d only start tinkering with his speeches for next week again. It could wait till the morning.

Through the patio doors, moonlight cast long inviting shadows in the sunken rooftop garden. It was his favourite part of the house, and one of the designs he was most proud of. The garden was surrounded by a ring of stone pillars and filled with plants and shrubs. It smelled of fresh earth and greenery. A little fountain in the centre splashed and burbled softly under the big glass dome.

It was a beautiful starry night, clear and still. He wondered if he could see Saturn. He pulled a cardigan over his shirt and wandered out into the garden, enjoying the stillness and beauty. On the wall near the doorway was a panel with buttons, and he pressed one. With a subtle whoosh of hydraulics, a glass panel in the dome above him began to slide back. He went over to where he kept his Celestron CGE1400 refractor telescope permanently set up on an electronic mount. The cold night air flooded in through the open dome. He let the scope cool for a while to get a sharper image, then set the coordinates for Saturn. The telescope automatically whirred across and up, aiming through the gap in the roof. Philippe took off the lens cap and looked into the eyepiece. The ringed planet was a thrilling, surreal sight that had captivated him since childhood. He never stopped marvelling at it.

A sudden lancing pain at the base of his neck crippled him. He staggered away from the telescope, disorientated and stunned. A heavy kick to the back of his leg crumpled him to the floor, and he felt a knee between his shoulder-blades, crushing him to the cold flagstones. Hard steel pressed against the back of his head. A quiet, calm voice in his ear said, ‘Any noise, you die.’

Aragon was helpless. He tried to roll over on his side and look up. The man towering over him was dressed in black. Eyes looked at him impassively through the slits in the ski-mask. Moonlight glinted on the steel of the gun pointed at his head.

Chapter Fifty-Two

‘Who the hell are you?’ Aragon said in a daze. He lay back in the armchair, his chest heaving fast with panic and shock. The intruder had marched him into the house and made him sit. His first thought had been that the man was an assassin come to kill him. Why hadn’t he? The gun was back in its holster. The intruder reached up a black-gloved hand and pulled off the ski-mask. Aragon winced at the pain in his neck, and rubbed his shoulder. Why was the man letting him see his face?

Ben sat opposite him in a matching armchair. Between them, a polished pine coffee table shone in the dim light. ‘Someone who needs your help,’ he said.

Aragon was taken aback. ‘You break into my house and point a gun at me, then you say you need my help?’

‘That’s how it is.’

‘People usually approach my office for that kind of thing,’ Aragon said.

Ben smiled. Aragon had guts. He liked him. ‘When you hear what I have to say, you’ll understand why I couldn’t see you the normal way.’

Aragon’s brow creased. ‘I don’t know if I want to hear it.’

‘I don’t know if you have a choice,’ Ben said.

‘You won’t get away with this. There are security cameras watching this room right now.’

‘No, there aren’t,’ Ben said. ‘This apartment is the only bit of private space you have left. You relish it. You wouldn’t let them put cameras in here.’

‘How the hell did you get past the guards?’

‘Never mind that,’ Ben said. ‘Just listen to me. If you help me, I’ll help you in return.’

Aragon laughed. ‘You’ll help me? By doing what?’

‘By giving you the people who murdered Bazin.’

Aragon stopped laughing and went pale. ‘Roger?’

Ben nodded. ‘Your mentor. Your friend.’

Aragon was quiet for a few seconds. He gulped.

‘Roger wasn’t murdered,’ he said in a low voice. ‘He died in a car accident.’
