Official Decrypt

Top Secret: For your eyes only

We found the attached message hidden in the underlying code of an image sent in junk mail to people at the US embassy. It might have slipped past us, but luckily, Harry and I had already figured out that they might try to communicate this way. The conspiracy had avoided detection for over a century, so they were unlikely to make the mistake of sending messages explicitly addressed to one another. It is always best not to make links between members of a network and a well-hidden message in junk mail avoids that risk, especially if it is widely distributed by one of the bot networks, like this one. I was too focussed on the decrypt at first and wasn’t reading what it said until I found her name staring back at me at the end. Perhaps we should have already realised that Trinity could be involved, but it never occurred to me that her name was anything other than a coincidence. The fact she’s Charlie’s niece should have lit up the lights on the dashboard though and I am worried that Harry didn’t raise it. Perhaps he is already shadowing her, and didn’t like to say so out of loyalty, but he didn’t tell me that, and somehow, I think he would. I think it’s more likely that she’s beyond suspicion in his mind. She has played an important role in his network for fourteen years, and the fact that she might be a double agent will be a real blow. That was bad, but it wasn’t the worst of it. The detail Trinity gives on the conspiracy’s recent activities is truly frightening. What could they want at the heart of the pandemic response groups? Surely they can’t have been responsible for the outbreak? And what were they doing at COP? I desperately want to take this to Harry, to talk to him about it, but the final paragraph stopped me in my tracks. Why on earth does Trinity think I might join them? What have I said or done that would make them think I could be a traitor? And will that make Harry distrust me too? I’m not sure I can take that risk. I might have to finish this mission alone.

Top Secret: For your eyes only

Charlie, I don’t think you should have come to London; we can’t risk meeting, and your arrival has been noticed by BOSS heightening suspicion. Harry’s team is actively investigating our organisation and we have to do everything we can to put them off the scent. Unfortunately, I’m working with very constrained resources. Despite all our pandemic preparations it has been hard work over the last eighteen months. As planned, we used the crisis to embed more operatives at the heart of government decision making. Under the cover of SAGE and the other new committees, we now have a network of scientists and engineers in Whitehall with the direct ear of senior civil servants and politicians. They also helped us to infiltrate COP, giving us direct access to a number of other governments that had remained beyond our reach. While we were not able to fully deliver on our plans for that event, the connections we made with some of the world’s largest companies and smallest states will surely pay off in the medium term. On the downside, I haven’t had the capacity I need to work on the BOSS investigation into our organisation that is being run from the Archaeology Division here at GCHQ. I had hoped that assignment meant that the case was regarded as low priority, but Harry assigned his best agent, Jodie, to run it and gave her almost unlimited resources. She has teams all across the UK trawling through the papers we left behind at the Lighthouse and trying to work out what they mean. I am so angry at myself for that, but I have personally checked, and all the major items from the foundation archive were shipped out to Massourie and have been secured at the Park. I assigned a team to make sure that the key documents were properly encrypted in case Jodie’s team finds them, but given the talent she is working with, I now think we might need to take further steps, and I plan to visit the HQ as soon as I can get away. Whether or not Jodie and her team work out what we are doing, the best way to make sure that Harry does not find out might be to convince her not to tell him. I have been carrying out some background checks, and I am wondering if we should just try to recruit her directly. If she was working with us, then I’m sure she would see the need for secrecy. The direct approach is risky, but the organisation has never shied away from that before, or you and I wouldn’t be working for it. I think it is a risk worth taking. Your loving niece, Trinity
