    Who is [Edited by Harry – no spoilers!]?

    [And anyway, are you sure you have that right? Harry]

    It could be […] “YES”.

    I wonder what the cipher is, and also, is it always a keyword sunstitution?

    What/who is “[Spoiler! Harry] ? I figured that was the keyword used in Challenge 3A!

    Will do. As always, I am really enjoying the developing story and I am looking forward to seeing what will happen next – these messages are most certainly not “narrés irritantes”. Oops, done it again, and again. Ok, I mean ‘Will do from now on!’.

    Harry, do you have the full newspaper article about spyclists? Could you post it?

    It seems that this article come from the “Daily Herald” of may 24 1937.
    It can be bought here :

    Madness don’t pay. At that age, it should be in the public domain.

    Harry, is the intended keyword PHOTO? Just asking so that next week I can archive the solution.

    Harry, will we ever know the answer to the puzzle at the end of 3B? I tried but couldn’t figure it out!(yet?)

    Hello Harry,

    If you read back the earlier messages you will see that the spyclists have agreed, for now to restrict themselves to substitution or transposition ciphers, and frequency analysis should have ruled out a substitution cipher, so you should be trying to break a transposition cipher. You can find a bit about this in the BOSS codebreaking guide. Cribs are your friend, in other words, you can try looking for particular words (or rather jumbled forms) that you expected in the message.

    Any use?

    Harry
