The Promise. Katerina Diamond

and these games are very competitive. It’s all about displaying how popular you are and how much you’re worth in the game.’

      ‘How much was Erica worth? What was her rank in the game?’ Imogen asked.

      ‘She was a middle-level player,’ Gary said, ‘which is actually pretty high. Imagine it in terms of a Hollywood hierarchy in the real world. She would be a supporting soap star, as opposed to an A-list movie star.’

      ‘I don’t really understand anything you just said,’ Adrian interjected.

      ‘I get it. I may or may not have been on something similar to this in the past. Briefly, mind,’ Imogen said.

      ‘Really?’ Adrian shot her a look and she scalded him with her eyes, hoping he would understand what she was trying to do. Adrian probably couldn’t understand what it was like for Gary, who was lovely but didn’t have the same confidence with women that Adrian did. She had witnessed Adrian’s effect on the opposite sex on several occasions, mystifying as it was, but Gary certainly had completely different experiences when it came to women.

      Imogen noticed that each name had a country flag next to it; she assumed it was the user’s country of origin.

      ‘Is there any way to know where the people who visited are from, like exactly?’ she asked Gary.

      ‘Maybe, if she had a tracker set into the code. It’s pretty standard practice and easy enough to do. It looks like she was well into this game, her wall is quite artistic and stuff, a lot of specialised coding – it wouldn’t be unrealistic to assume she had a tracker built in. Once we get the other side of the account it should be easy enough to find out. Although you can fool the tracker by tricking it into thinking you are from somewhere else by using a VPN, but not everyone would even think to do that, so you never know.’

      ‘Can you track on all social media then?’ Imogen asked, unfamiliar with Gary’s capability or even which code the game developers used.

      ‘It’s much easier on these sites where you power your own HTML code and have access to customise themes and designs through the code itself. Not really as straightforward in apps that don’t give you that kind of access.’

      ‘And what’s this counter for?’ Imogen said.

      ‘It’s how many visits her page has received since she started on the game.’

      ‘Oh good, it’s over a hundred thousand,’ Imogen said sarcastically.

      ‘Looks like she’s been playing it for a couple of years. There’s also a chance that this isn’t her first account. There’s one thing for sure though.’

      ‘What’s that?’ Imogen said.

      ‘She definitely had a personal computer or laptop; there is no way she would have been able to maintain this level of involvement with just a phone. So, if you can find that, you will find out a lot more about her and who she interacted with. Nina Lawless has a big online presence. She was pretty obsessed with this game and, the way it works, it makes sense to have more than one profile, so a dummy account to interact with you to make you look more popular.’

      ‘Really? People do that?’

      ‘Yes, any one of these could be Erica’s profile as well. She might have wanted to make someone jealous, make fake money or tokens in the game to send herself gifts. Who knows?’

      ‘You understand all of this? I can’t get my head around it,’ Adrian said to Imogen, shaking his head.

      ‘Is there any indication of a possible suspect among the evidence we have so far?’ Imogen asked.

      ‘I think judging by the way her attacker has managed to avoid all cameras and stuff, we should work on the assumption that he lives quite close to here. At least in the UK. Once we get into the account I can look at her tracker if she has one. I think most people do,’ Gary said.

      ‘What if she doesn’t?’ Adrian asked.

      ‘How about we set up a profile for me?’ Imogen said, surprising herself. ‘Gary, you would have to be in control and keep an eye on it. But let’s assume the guy found her through that. If he knew where she was from, then it’s possible that he was specifically targeting someone from this area, someone close to him.’

      ‘Not a bad idea, I guess,’ Gary said.

      ‘You can try and connect with the people that she connected with. See if any of them raise any alarms,’ Imogen said to Gary, whose face lit up.

      ‘Ooh catfishing, my favourite,’ Gary said.

      ‘You worry me, mate,’ Adrian said.

      ‘Can you be a convincing girl though?’ Imogen asked Gary.

      ‘Can you?’ Adrian said to Imogen. Imogen thumped him in the arm, relieved to see the trace of a smile on his face.

      ‘This isn’t my first rodeo,’ Gary said. Adrian raised his eyebrow; Gary’s capacity to know things was genuinely impressive. He didn’t know where he found the time.

      ‘OK – make me a profile and I’ll send over some suitably cheesy photos,’ Imogen said. ‘Gary, can I borrow your cat?’

      Gary laughed. ‘Um, sure? I can take the photos for you if you want? I’ll drop by your place with my camera.’

      ‘OK, great.’

      Adrian was still staring at the website. ‘What I don’t get is why use fake photos? Like photos of models and stuff?’ he said.

      ‘Because some people collect other people for friendship, and some people collect styles of pictures.’ Gary clicked on a profile picture that was electric blue digital art; sure enough the rest of the wall was full of electric blue profile pictures interacting with the user. Almost like little cliques within the game.

      ‘You’ve got a handle on this though? You know how to play? You can get up to the same rank as her?’ Imogen said.

      ‘I can. I kind of love this sort of thing. I’ll let you know tomorrow how it’s going. Why are we using your photos though? Why not a fake?’

      ‘In case anyone wants to meet, or video chat or whatever.’

      ‘Try to make your pictures a bit naff, don’t look too hot or anything. Look normal and like a cat person,’ Adrian said.

      ‘What does a cat person look like?’ Gary said, that offended tone in his voice again. Was the bromance over? Adrian seemed to be getting on his nerves, or maybe it was something else.

      ‘I don’t think there’s any danger of me looking too hot,’ Imogen said.

      ‘Nonsense, Grey, you’re a solid nine.’ Adrian got up and walked out.
