Reply To: Yet another 10B post
(Harry: I have tried to be a little cryptic, but I do not know if it is too early for discussion about the key.)
Following on from Case File 10.8, I have been wondering about the key to 10B. It had me going round in circles for a bit, but I think I have it. However, it does not quite seem consistent with Case File 10.8. [Edited by Harry]
Since the cipher you allude to had not been invented at this point, it would be surprising if the assignment was that accurate! Think of 10.8 as pointing you at the broad structure of the cipher rather than the details and you should be fine. Harry
