Top Secret: For your eyes onlyI have drawn a blank in my enquiries about Caistor St Edmund and even Harry is getting nowhere with his contacts in the MOD. We both agree that the silence is very worrying. This is clearly an area of interest as it presents a crucial front in any potential invasion so we would have expected some interest in our intelligence, or at least some push back warning us to keep away from basic defence installations like listening posts. The fact that no-one wants to talk about the facilities in the area suggests that it is all very hush hush. Something important is happening there and we probably want to find out what. Our agents in London kept watch for the touring party and recorded them as arriving at Liverpool Street. The group consisted of twenty three cyclists who split up and stayed with members of local scout groups while their leader was hosted by a member of the local Ortsgruppe. We received reports from K’s network that the group has been invited to stay with the Spalding Rotary Club in Lincoln and we need you to investigate any reports you can find about that visit. I will continue to press for information about strategic developments in Norwich and Norfolk. The Akela initiative has been given approval and I will be setting that up this week. The intention is to enroll leaders and members of local scout groups, train them in counter-intelligence and use them to host the spyclist touring groups in the hope of getting inside their operation. Since future communications may include sensitive operational details of this initiative I intend to increase security by moving to a blocked keyword cipher. The attached document was intercepted by our London agents when the party posted it on arrival at Liverpool Street. As usual it was addressed to Tirpitzufer. Primary analysis suggests that it does not use a substitution cipher. More to follow. Pearl.

Top Secret: For your eyes onlyDear Uncle Wilhelm, Our journey to London was short and charming, the trains rattling along the British tracks through open fields and countryside. Their roads may be almost impassable in places, but these iron tracks provide a very usable way to travel across country at speed. Our hosts in London have organised for us to stay with members of the British Scouting Movement, though I will spend the next few days with the Ortsgruppe, exchanging news about the Fatherland and their activities here in the capital city. It was difficult to tear ourselves away from the pleasures of Norfolk and the City offers far fewer opportunities for open exploration. On the other hand the bustle of the city, as in Berlin, offers a certain anonymity and it is in some ways relaxing to leave behind the gossip and inquisitiveness of village life. As you suggested we will use our time here in London to support our brothers and sisters and to reassure them that they have not been forgotten. I will pass on the gifts that you entrusted to me, together with your instructions for their use, as we did in Caistor St Edmund. The radio you sent me is remarkable. It is able to pick up signals across the spectrum, even from Berlin itself, though I am enjoying listening to British radio, especially the home service. They are building a chain of transmitters across the country which provide information throughout the day and night, something that I think you might want to take into account when planning our own radio services. I am assuming that there are no changes planned for our itinerary, but if there are then perhaps you could forward them to our hosts in Spalding, with a copy sent post-restante to CsE. Yours sincerely
