+harry we managed to tap the phone lines in oslo and intercepted german military police reports to
+the ss headquarters they established that the gunner side operation was effective in wiping out the
+existing stocks of heavy water but that the nazi engineers were able to restart production this was
+confirmed in communications smuggled out of the plant by jomar brun and e in nar skinner land the
+chief engineer and designer of the plant who are still working there as soe agents the information
+was sent to intelligence headquarters in london in toothpaste tubes using a cipher developed for
+boss by leo marks this intelligence was passed to usaaf who started to develop a plan to bomb the
+plant running the risk of significant civilian losses luckily one of our boss officials spotted the
+map on the wall of a briefing room during a protocol visit and realised what it was he flagged the
+operation and got me involved i was able to contact swallow via the oslo branch of mil org and we
+have been working together with usaaf to refine the mission despite the risks they agreed to a
+daylight raid in the hope that the added accuracy would reduce norwegian casualties unfortunately
+the raid was a mixed success as you can see from the attached report it is double encrypted again
+but was alot tougher to crack they have used an affine shift for the substitution phase before using
+the same sort of transposition take a look and let me know what you think meanwhile i will try to
+contact ronn enberg to see what he wants to do next given the need to protect our network i will
+increase the key length for my message to you next week to atleast six
