‘I’m sorry,’ Ben said to Simon, jerking Roberta’s arm and cutting in before she said too much. ‘My fiancée’s upset. We’re leaving now.’ He pulled her aside, leaving the inspector standing there staring keenly at them as assistants scuttled around him.

‘Your fiancée?’ she hissed at him. ‘What’s that supposed to mean? And let go of my arm, you’re hurting.’

‘Shut up. You don’t want to spend the next ten hours being grilled by the police, and neither do I.’

‘It’s not suicide,’ she insisted.

‘I know,’ he nodded. ‘Now listen to me. We’ve only got a few seconds. Is anything in here different, moved, changed in any way?’

‘Someone’s been through the place.’ She motioned towards his desk and tried not to look at the huge vertical splatter of blood on the wall and ceiling. The desk was empty, Michel’s computer gone.

‘Rigault, get these people out of here! Come on, let’s move!’ Simon was shouting from across the room, pointing at them.

‘We’ve seen enough,’ Ben said. ‘Time to go.’ He led her towards the door, but Simon intercepted them. ‘I hope you’re not thinking of leaving town, Dr Ryder? I might want to talk to you again.’

As they left the apartment, Simon watched them with a frown. Rigault gave him a knowing look and tapped his head with his finger. ‘Crazy Americans. They see too many of their Hollywood movies.’

Simon nodded pensively. ‘Maybe.’

Montpellier , South of France

‘Marc, pass me the screwdriver. Marc…Marc? Where are you, you dozy little shit?’ The electrician got down from his ladder, leaving loose wires hanging, glaring around him. ‘That little sod’ll never learn anything.’ Where had he disappeared off to now?

The kid was a liability. He wished he’d never given him a job. Natalie, his sister-in-law, doted on her son, couldn’t see that he was just a loser like his father.

‘Uncle Richard, look at this.’ The apprentice’s excited voice echoed up the narrow concrete corridor. The older man put down his tools, wiped his hands on his overalls and followed the sound. At the end of the shadowy corridor was a dark alcove. A steel door was hanging open. Stone steps led down into a black space. Richard peered down. ‘What the hell are you doing in there?’

‘You’ve got to see this,’ the kid’s voice echoed from inside. ‘It’s weird.’

Richard sighed and clumped down the steps. He found himself in a huge, empty cellar. Stone columns held up the floor above. ‘So it’s a bloody cellar. Come on out, you’re not supposed to be in here. Stop wasting time.’

‘Yeah, but look.’ Marc shone his torch and Richard saw steel bars glinting in the darkness. Cages. Rings bolted to the wall. Metal tables.

‘Come on, beat it out of here.’

‘So what is it?’

‘I dunno. Kennels for dogs-who gives a shit?’

‘Nobody keeps dogs in a cellar…’ Marc’s nostrils twitched at the smell of strong disinfectant. He shone his torch around and saw where the smell was coming from, a concrete sluice cut into the floor leading to a wide drain cover.

‘Move it, kid,’ Richard grumbled. ‘I’m going to be late for the next job-you’re holding me up.’

‘Wait a minute,’ Marc said. He stepped over to the glinting thing he’d seen in the shadows and picked it up off the floor. He studied it in the palm of his hand, wondering what it meant.

Richard strode over to the lad, grabbed him by the arm and pulled him towards the steps. ‘Look,’ he warned. ‘I’ve been in this job since before you were born. One thing I’ve learned, if you want to stay in work you mind your own business and keep your mouth shut. OK?’

‘OK,’ the boy mumbled. ‘But-’

‘No buts. Now come and help me with this bloody light.’

Paris

For the last four years, Ben had worked alone. He relished the freedom it gave him, the ability to sleep where he wanted, to move as fast and as far and as light as possible, to slip in and out of places alone and inconspicuous. Most important of all, working alone meant that he was responsible for himself and himself only.

But now he was lumbered with this woman, and he was breaking all his own rules.

He took a convoluted route back to the safehouse. Roberta’s puzzled expression deepened as he led her down the cobbled alleyway, through the underground parking lot, and up the back stairway to the armoured door of his hidden apartment.

‘You live here?’

‘Home sweet home.’ He locked the door behind them and punched in the code for the alarm system. He flipped on the lights and she gazed around the apartment. ‘What is this, minimalist neo-Spartan?’

‘You want a coffee? Bite to eat?’

‘Coffee’s good.’

Ben went into the kitchenette and lit the gas ring under his little percolator. After a few minutes it bubbled up and he served the coffee with hot milk out of a saucepan. He opened a tin of cassoulet, heated it up and dumped the steaming sausage-and-ham stew onto a couple of plates. He still had half a dozen bottles of red table wine. He grabbed one and pulled the cork.

‘You should eat something,’ he said as she ignored her plate.

‘I’m not hungry.’

‘OK.’ He finished his own plate, then pulled hers across the table and wolfed down the last of the stew with gulps of wine. As he ate, he could see she was shaking, her head in her hands. He got up and put a blanket around her shoulders. She sat in silence for a few minutes. ‘I can’t stop thinking about Michel,’ she whispered.

‘He wasn’t your friend,’ he reminded her.

‘Yeah, I know, but still…’ She sobbed, wiped her eyes and smiled weakly. ‘Pretty stupid.’

‘No, not stupid. You have compassion.’

‘You say that as though it were a rare thing.’

‘It is a rare thing.’

‘Do you have any?’

‘No.’ He poured the last of the wine into his glass. ‘I don’t.’ He looked at his watch. ‘It’s late. I’ve got work to do in the morning.’ He drained his glass, jumped up from his chair, and grabbed a pile of blankets and an armchair cushion. He chucked them on the floor.

‘What’re you doing?’

‘Making up a bed for you.’

‘Call that a bed?’

‘Well, you could have had the Ritz if you’d wanted. I did offer, remember?’ He saw her look. ‘It’s only a one-bedroom flat,’ he added.

‘So you make your guests sleep on the floor?’

‘If it’s any consolation, you’re the first guest I’ve had up here. Now, can I have your bag, please?’

‘What?’

‘Give me your bag,’ he repeated. He snatched it from her and began rifling through it.

‘What the hell are you doing?’ She tried to grab it back from him. He pushed her away. ‘I’ll have this,’ he said, pocketing her phone. ‘The rest you can keep.’

‘Why are you taking my phone off me?’

‘Why do you think? I don’t want you making any calls from here behind my back.’

‘Boy, you really have a big problem with trust.’

Roberta couldn’t sleep well that night, couldn’t shut out the memory of the day’s events. What had started out like any other day had turned her whole world upside-down. Maybe she was crazy, hanging on here when she could have taken the money and been on a plane home first thing in the morning.

And what about this Ben Hope? Here she was, locked in a hidden apartment with a guy she’d only met that day and barely knew. Who was he? He was attractive, and he had that winning smile. But there was that coldness, too, the way he could look at her with those pale blue eyes and she couldn’t tell what he was thinking.

There was another thought that wouldn’t go away. It was the knowledge that someone was interested in her research. Very interested indeed. Interested enough to kill for it. That meant several things. It meant that someone was threatened by what she’d been discovering. Which meant it had real value. She was on the right track, and even if it was a dangerous position she was in, she couldn’t help feeling a tingle of excitement. She had to know more.
