‘Let’s sit,’ Ben said a few yards further on, motioning towards a green park bench under the shade of the trees.
Roberta nodded. She sat on the bench beside him and gazed across the park in the direction of the kiddies’ roundabout and swings in the distance. They could hear the child’s gurgling laughter as his mother began to swing him gently back and forth.
Ben said, ‘Start from the beginning.’
‘Claudine and I went back a long way. When I was teaching in Paris years ago, she used to lecture at the Sorbonne. We met through some mutual acquaintance I don’t even remember now. We hit it off, became friends, stayed that way ever since. After I went to live in Canada she used to call me every so often, birthdays, Christmas, and emailed me now and then to keep me updated about her work projects. Some of them were real fascinating. I hadn’t heard from her in a little while, just assumed she must be busy at work or something. Then yesterday, I get this letter from her by registered mail.’ Roberta glanced anxiously at Ben. ‘I thought it was strange that she’d write me that way, instead of the usual email. When I opened it I saw it was more like a note, real short, and you could see it was written in a hurry. She said she was in deep trouble, that she was certain she was being followed and that something bad was going to happen to her. Said not to contact her by email or phone because they’d know. They were watching every move she made.’
‘Who was?’ Ben asked.
‘If she knew, she didn’t say.’
‘Have you got the letter with you? Can I see it?’
She shook her head. ‘The Paris cops have it now.’
‘Did it say any more than that?’
‘She asked me to go to Paris to help her. To hurry before … before it was too late.’ Roberta gave a bitter laugh.
‘No indication what it was about?’
‘No, she said she’d explain everything once I got there. Said I was one of just two people in the world she could turn to.’
‘Why not the police?’
‘Something else was going on, Ben. Something that meant she couldn’t go to the police. The last line she wrote was this rushed scrawl that just said “If something happens”. That was it. Underneath were a bunch of figures. She didn’t even sign her name.’
‘Figures?’ he asked.
Roberta dug a crumpled sheet from her handbag and handed it to him. ‘I copied them out before I passed the letter on to the cops. Still have no idea what they mean, though.’
Ben looked at the paper and studied the three lines of what appeared to be some kind of cipher.

Codes weren’t his favourite things. He stared at the sheet for a few moments, completely baffled, until the two letters in the top line suddenly flew out at him and he realised what they were. They stood for North and East.
‘I don’t know about the rest,’ he said, ‘but the top line’s definitely a set of GPS co-ordinates, scrambled together. If you teased it apart it’d pinpoint a geographical location.’
‘You’re sure? What location?’
‘I’m sure. But that’s something we can come back to afterwards. Keep talking.’
‘What could I do?’ Roberta continued. ‘She was my friend. I cancelled everything. Managed to get on a late flight to Paris. I was so worried, all I could do on the plane was sit there trying to understand what those goddamn numbers meant, but it was no use. I got into Paris just after seven this morning and took a cab straight to Claudine’s apartment in Montmartre. She lived alone on the top floor of this crumbly old building in Rue des Trois Frères. When I arrived, there was a police car and a van parked outside but I didn’t think anything of it at first. Then as I was heading up the stairs, these cops and forensics people were coming down, with the concierge who looks after the building. I asked if everything was okay. They asked me who I was coming to see. I said “Claudine Pommier”. They told me what happened.’
Roberta paused for a moment to compose her emotions. ‘It was her neighbour, Madame Lefort, who found her the morning after she was killed. The door was open, and there she was on the bed. Old lady had to be hospitalised for shock. It’s so … so horrible.’
‘It’s bad,’ Ben said. ‘I’m sorry.’
Roberta sniffed, dabbed away a tear and went on. ‘It happened on the same day as the postmark on the letter. She must have posted it just a few hours before she died.’
‘Did she have family?’ Ben asked.
‘She lived alone. Lost touch with her relatives a long time back. Parents were a couple of religious assholes who disapproved of her career in science … oh, shit, Ben. I didn’t mean—’
‘It’s okay.’ He smiled.
‘The only person in her life was a bum of an ex-boyfriend, Fabien. But he was never around even when they were together. The cops couldn’t trace him, had to get a work colleague to identify the body in the morgue. Thank Christ I didn’t have to do it. You can imagine …’ Roberta shook her head, as if trying to clear the horrific picture from her mind. ‘Meanwhile, they were still combing through her apartment for evidence, DNA. Nothing was stolen, apparently. The cops asked me all these questions, who I was, what I was doing there. I gave them the letter she’d sent me, but they didn’t seem interested that Claudine had known beforehand she was in danger. All they could talk about was this bricoleur. Then I talked to the concierge, Madame Bunuel. Gave her my card and said to call me right away if there were any developments. That was when I noticed him the second time.’
Ben narrowed his eyes. ‘Noticed who?’
‘About thirty, tall, dark hair. I thought he was a plain-clothes detective at first. He was hanging around in the background while I was talking to the other cops. Then while I was talking to the concierge, there he was again. Looking at me kind of strangely. But I didn’t think much about it at the time. I left there soon afterwards and just started walking. I was so badly shaken up about what happened to Claudine, I barely knew where I was, let alone where I was going. Before I know it I’m heading into a metro station. Abbesses, I think. Then I noticed the guy from the apartment building again, following me down the escalator, through the tunnels, hanging back like he didn’t think I’d spotted him and didn’t want me to. I kept walking. Tried to lose myself in the crowd. By the time I got to the platform I couldn’t see him anymore. I was thinking I must have imagined it. But then as the train pulled into the station, there he was again, just a few steps away. Staring at me. It totally freaked me out, Ben.’
‘He didn’t do anything?’
‘Not then,’ she said. ‘He never came any closer, didn’t speak to me. I got on the train and he boarded the same carriage. I didn’t look at him directly but I could see his reflection in the window. Just standing there at a distance, still watching me in this real creepy way. He had his arm up to hang onto the safety strap, and his jacket was hanging open. He had a gun in there, a black handgun, like 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
