Before trying this you should read the introduction to Virtual Colossus.
This scenario is an intercept of 5668 characters with K2 and P5 limitations
on the "Bream" patterns, accessed in Virtual Colossus as "BRPcipher"
When you have got out all the wheel starts you can access the same
cipher text and patterns in Virtual Tunny, put in the starts and then
decipher the message.
You may need to print this then
go look for tools.
