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 at the blue Vauxhall the older man was receiving instructions via a mobile phone. He listened until his instructions were complete, then gave a short nod to his colleague.
The driver opened the boot. He took out the black holdall from inside. It sagged heavily in his hand.
The two men scanned the near-empty park. Within a few seconds they’d located their target on the green wooden bench in the distance and taken note of the unknown male accompanying her. The men exchanged glances when they saw how the target’s companion was dressed.
It was no ordinary camera that was built into the mobile phone the older of the two men was carrying. He quickly, discreetly, used it to snap the figures on the bench, then redialled a number. ‘She’s not alone,’ he said when the voice replied on the line. ‘She’s talking to a priest.’
Pause. ‘Yeah, that’s what I said. I’m sending the image now. Got it?’
‘I’ve got it,’ said the gruff voice on the other end. ‘I see them. Okay, it’s her last confession. His too. Make it quick and quiet.’
The call was over. The two men divided the contents of the holdall. Then moved unnoticed around the edge of the park to their position.
Chapter Five
The word research , from the lips of Roberta Ryder, held certain negative past associations for Ben. After all, it had been some bizarre experimental research of her own that had first not only brought them together but drawn the attention of ruthless people who’d very nearly succeeded in killing them both.
‘You told me Claudine was a lecturer,’ he said. ‘Lecturer in what?’
‘Physics,’ Roberta replied.
‘It doesn’t sound very dangerous.’
‘But then, what do you know about physics?’
He said nothing. Aside from weapons ballistics, the complexities of calculating long-range rifle bullet trajectories, the cold mathematics of war and
