Top Secret: For your eyes only
Harry, I am sure this must be very hard for you as I know that Charlie was a good friend, but we can’t let that cloud our judgement. Given the content of her letter last week we have to assume she is involved somehow, and work on that basis. Having said that, Charlie doesn’t actually say anything that proves that she is a member of the Lighthouse Conspiracy. Of course, she is an experienced agent, so that might be deliberate, but she does refer to the Trinity group and it’s possible that the Americans were already investigating the conspiracy under that code name. Everything in the email takes on a slightly different meaning if we view it that way, but that raises the question of why they didn’t share the intelligence with us. In the meantime, I tried to track back through Agatha’s record to see if there is anything to suggest that she might have been a double agent. Nothing mentioned in the file raised a flag, but I noticed two things in the attached vetting summary: After her initial run in with the German treasure hunters seeking the Babylon stone she went on the run, and papers reported that she was a passenger on the Titanic. As you know, she never boarded, and used that tragedy as a way to disappear. According to the report she did not reappear for over fourteen months, when she was recruited as an intelligence source in Cairo for the British Embassy. That raises the question of what she was doing for the year. The other thing that struck a chord was the mention of Massourie. George Everest built a retreat there, and his name came up when I was researching the security files of Charles Babbage. It seems that Babbage was introduced to ideas from Indian mathematics by Everest and this influenced the development of the Difference Engine and its successors. Mary Boole wrote about this in her letter Indian Thought and Western Science in the Nineteenth Century. Given what CH wrote about the Difference Engine, this might be more than a coincidence, though perhaps I am reading too much into it. For the sake of our trainees, I should say that the vetting report has been double encrypted using a Vigenere with a second, very simple, twist; I mention it because that threw me off for a while. I suggest that they reflect on what might be going on! Given that we are now trying to avoid raising suspicion by the US and the Lighthouse Conspirators I think we should change our own protocols, so I have switched up to a transposition cipher. I suggest you do the same next time, though you could try something else like a Polybius square. JodieMission Intercept 6B: Vetting update Agatha Highfield

Top Secret: For your eyes only
Vetting update Agatha Highfield Summary June MCMXXXIII: Agent AH is a well-regarded member of the intelligence community with strong connections in the UK and the USA. She has worked extensively with H on major cases and has full access at Top Secret and above. This is a standard periodic review of her clearance. AH joined the organisation one month before the outbreak of the Great War and was initially assigned to Cairo because of her expertise in the Levant. On the outbreak of the conflict she was reassigned to duties in France, where she provided regular and valuable reports on troop dispositions while coordinating sabotage and propaganda. Since Versailles she has been a lead operative in our Europe office, specialising in the Weimar Republic. AH has no permanent base in the UK and is known to spend significant periods in Africa and Asia. At the end of her most recent mission, she took a walking holiday in India, staying in Massourie. She has few friends, and a lifestyle consistent with her known resources, both on and between operations. On her recent return to the UK, AH took an apartment in Greenwich where she lived until her current mission in Germany began. She had a small number of visitors during this period, including Chadwick, Cockroft and the Hungarian scientist Szilard. Presumably this is what led to her latest investigation, Die Alchemisten, which was launched at her own initiative. Before leaving for Munich AH drafted a paper recommending the launch of a new branch of the agency dedicated to forward planning; she nicknamed this group the Lamplighters. The stated aim was to prepare long range reports outlining future threats in order to forestall them. The proposal was rejected by the Foreign Secretary, who regarded it as unlikely to succeed in its stated aims and very likely to distract from the more immediate threat posed by Facism. There are no current grounds for concern, but as a major asset the clearance for AH should be revised biannually.RULE REMINDER: Rapid fire multiple submissions put an unreasonable load on the servers and make it difficult for others to submit. Anyone who makes an unreasonable number of submissions will be open to disqualification. In the first instance this will mean that anyone who submits more than 20 times in 10 minutes will be disqualified.
