a Glock or something. I didn’t imagine it.’
Ben felt like pointing out that French plain-clothes detectives routinely carried concealed sidearms in shoulder holsters on, or even sometimes off, duty – but he kept quiet and let her go on talking.
‘I was terrified the carriage would empty and I’d be left alone with him. I waited a couple of stops, then at Saint-Georges I got off. He did the same. Then just as the doors were about to close I pushed through the crowd and jumped back on again – like the trick they do in movies? Worked. I left the sonofabitch standing there on the platform.’
‘And then?’
‘Then nothing. I stayed on the line all the way to Concorde and then ran like hell back up to the street and hailed the next cab I saw.’
Ben was silent for a moment. ‘You mean that’s all that happened?’
Roberta stared at him. ‘What did you want to hear? That he abducted me at gunpoint? Tried to punt me onto the electrified rail in front of all the crowds?’
‘I thought perhaps—’
‘Ben, you weren’t there,’ she said imploringly. ‘It was obvious what was happening. I was so scared. That’s when I had the idea of calling you.’ She paused, blushed a little. ‘I … I’ve looked you up a few times. Maybe more than a few times. So I knew you were in France. At least, I thought you were. When I called, this Jeff person told me you’d moved to England. Gave me an address in Oxford but said you’d been spending a lot of time at this village called Little Denton. Anyway, I didn’t know what else to do except jump on the next Eurostar. Arrived in London a couple of hours ago, rented that car and drove like crazy all the way to Oxford. Took me forever to find your place, then you weren’t home, so I found this place on the map and came out here hoping I’d find you. Ben, please. I’m exhausted and I’m terrified. You’ve got to help me.’
Ben was silent for a minute as he tried to put the breathless rush of details together in his mind. ‘I’m confused about this man who followed you from your friend’s apartment,’ he said. ‘You told me before you thought he was a detective. Now it sounds like you’re trying to imply he’s the murderer.’
‘Maybe he is,’ she said. Her expression was intense.
‘Roberta, think about it,’ he protested. ‘The serial killer? You really believe this “handyman” would linger about the scene of his own crime pretending to be a plain-clothes detective, hoping to knock off his victim’s friends as they came to visit? He might be a maniac, but nobody’s that crazy.’
She shook her head. ‘Uh-uh. That would be a little far-fetched, even for me. That’s why I’m totally certain that this serial killer thing is a blind alley. It wasn’t the “handyman” who killed Claudine. Don’t you see? It’s just been set up to appear that way. Some bullshit story to lead the cops off the track while … Oh, Ben, don’t look at me like that. Like I’m some kind of paranoid conspiracy loon.’
‘I don’t think that about you.’
‘You mean, you don’t want to think it. But you’re thinking it.’
‘I don’t know what to think,’ he said. ‘If it wasn’t this sicko who killed her, then who did?’
‘How can I know that? Nobody does, that’s the whole idea. They do this kind of thing all the time, when they want to rub someone out who gets in their way.’
‘They do it all the time?’
‘Yes, they,’ she snapped.
‘All right,’ he said. ‘Leave that to one side. Next question: who came after you on the metro with the apparent intention of doing you harm?’
‘I don’t know that either.’
‘Roberta, if you don’t know these things, isn’t it simpler just to accept what the police say?’
‘Since when did you ever take a cop’s word for a single damn thing, Ben Hope?’ she demanded hotly. ‘You trust them even less than I do. Besides, the letter proves it’s not that simple.’
‘The letter we don’t have any more,’ Ben said. ‘And even if we did, it proves nothing.’
‘Hold on. She knew she was in danger. That’s the whole point.’
‘If this murderer hasn’t been caught yet, maybe it’s because he’s careful,’ Ben said. ‘Psychopaths are often extremely cunning and devious. Sick, but smart. They’ve been known to plan their attacks, weeks, months in advance.’
‘So?’
‘So he might have been watching your friend for some time before he struck. But maybe he wasn’t so careful that she didn’t spot him and somehow sensed that something wasn’t right about him. That could easily explain how she knew in advance that something was about to happen. She panicked.’
‘Oh, so you’ve got this whole thing figured out,’ Roberta snapped. ‘Then you tell me who the guy was on the train.’
He shrugged. ‘Maybe your first impression was the right one. He could have been a detective. You know the way their minds work. He might have wanted to ask you more questions. About the letter, perhaps. Or else maybe the whole thing is just …’ Ben checked himself from saying more. He’d already said too much, and could see the fire in her eyes.
‘Just what?’ she said fiercely.
‘All I’m saying, Roberta, is that maybe you need to think again. That maybe, for once in their lives, the police are right about this terrible thing that’s happened to your friend.’
‘And the rest I just cooked up in my imagination. That what you’re saying, Ben?’
‘You told me yourself you felt dazed, disorientated, after you left Claudine’s place. It would be understandable. People can suffer from all kinds of confusion at a time of great emotional stress.’
‘You’re so sure about this, aren’t you? In one way you haven’t changed at all, Ben Hope. You’re still just as much of a pigheaded bastard as when I first met you.’
‘Thanks,’ he muttered. ‘Remember, you came to me. You’re not giving me much of a chance here.’
‘What about the numbers?’ she demanded. ‘The GPS location and whatever else is there? You got a theory for those too? I have. If something happened to her, she intended for me to figure it out. There’s more to this, and I’m going to find out what.’
Ben leaned forward with his elbows on his knees, gazing at the ground between his feet and trying to understand. He knew Roberta well enough to know there was absolutely no point in trying to convince her to go home and wait for the police to do their job. And he couldn’t ignore the voice in his head reminding him of all the times he’d seen the cops botch everything up.
‘All right, then explain it to me,’ he said. ‘Someone murdered your friend, and now they’re coming after you, and it has something to do with this letter and a coded message. Who are they? What’s it about?’
Roberta paused to brush away a strand of dark red hair that had fallen into her eyes. Her brow was creased with strain. ‘Fact is, Ben, I think I know. Something tells me this all has to do with Claudine’s research.’
While they were deeply involved in their conversation, a hundred yards away at the other end of the park, a sleek black Audi saloon purred to a halt next to Roberta’s rental car. Its front doors opened and two men silently got out. Neither of them looked out of the ordinary. The one who’d been driving was in his early-to-mid thirties with nondescript brown hair and sunglasses, the other about ten years older, more heavily built, with a receding stubble of grey and eyes narrowed to slits against the early afternoon glare. They were casually dressed in jeans and lightweight jackets.
Neither spoke. As they both gazed impassively
