+the engineers harry brought with him wanted to take saws and torches to the table safe but neither
+of us were keen i could see that it would be worth alot to collectors and probably belonged in a
+museum harry said he agreed but i had a feeling he wanted it installed back in headquarters there
+was something proprietor i al in the way he looked at it it took the two of us eighteen hours to
+crack it but with a squadron of special forces from hereford guarding us there was no risk that my
+attackers would return i asked harry how he got authorisation to bring them in after all we still
+werent sure that there were any national security implications but he just laughed and pointed out
+that we were currently somewhere under new scotland yard and it hadnt taken much to convince the
+home secretary that we needed a proper security team to guard the shadow archive another team of
+analysts had camped on one side of the command centre and were combing through blacks codebook and
+the few papers that our antagonists had left behind from time to time one of the troopers would
+arrive with another box of documents retrieved from aside room or a more distant part of the archive
+labyrinth most could be decrypted quickly using the standard tools black had used a range of ciphers
+including substitution and transposition and almost none of it was harder than avi genere it was
+slow since the papers had to be handled with care and the scanner they had brought with them wasnt
+really designed for this sort of work a couple of times they called harry over to show him something
+and he read it nodded then came back to work on the safe as we worked we talked about what i had
+learned concerning the shadow archive and blacks secret work for the government harry didnt give
+much away but i had a feeling he had heard some of this story before and after the second time he
+was called away he seemed particularly thoughtful i asked him what was bothering him but he was
+enjoying being cryptic he said something about the balkan problem then muttered steve turners poem
+history lesson history repeats itself has to no one listens i couldnt get anything more out of him
+except some comment about working backwards through the papers so i turned my attention back to the
+safe the mechanism was bigger and heavier than we were used to and had been exquisitely made the
+components slid almost noiselessly over one another and the loud clicks i had heard when moving the
+table seemed to be the result of a broken cog tooth catching on the barrels that made it even harder
+to open what little noise the lock tumblers made was heavily disguised and we had to resort to
+drilling a small access hole to pass an endoscope into the interior it was as well we had taken the
+effort sitting in the middle of a pile of notebooks and papers was a small pile of what looked like
+explosives the safe was rigged to blow if we made a mistake

+the russo turkish war has been all that we feared russia has played her hand perfectly building
+support for action with her allies in germany and austria and effectively marginalising the british
+position while appearing to be amenable to an international solution our strategy of sowing
+confusion among the allies worked to delay the inevitable and i comfort myself that this delay
+achieved two things first we were able to develop our agent network within the diplomatic services
+of our enemies and second we were able to begin to negotiate with other leading powers to present
+our own solution to the turkish problem nonetheless my methods have not been universally popular in
+whitehall and i have expended considerable energy fighting enemies within now finally with the
+prospect that peace might be bought at the impending congress in berlin i can begin to hope for a
+resolution when i said this to playfair he corrected me and said that i must surely mean brought but
+it is my view that all victories worth winning are bought and often at great cost my hope is that
+our new methods of diplomacy might succeed at a much lower cost in lives all of the major powers
+have begun to see the gathering threat that war may erupt across the continent and all have realised
+that they have something more to lose from further conflict if we can control the agenda at berlin
+then i believe we may see away out of the crisis the pan slavic movement aims to unite the slavic
+states in the same way that germany and italy have been unified but is deeply split between those
+who believe that the locus of its power should lie within russia and those who seek a balkan
+solution the balkan states themselves remain divided with varied cultural and political ambitions of
+their own and no clear idea of which party should lead the unification perhaps that is misleading it
+is not that they lack a clear idea but rather that there are very many rival views and these are
+incompatible the question of how and whether this unification might be achieved is the principle
+concern of the congress all of the major powers william sure have a view but my focus is on the
+smaller states and parties my agents across the balkans have nurtured instability in the hope that
+we can bring pressure to bear through the mon the major powers of course the frenzied atmosphere of
+the diplomatic bazaar in germany will be rich in trading opportunities and i have heard rumours that
+we may gain cyprus cementing our control of the mediterranean trade routes at the same time by
+trading macedonia back to the ottoman state we hope to undermine russian territorial gains and
+perhaps to settle the balkan question permanently if so our agent network in bosnia will give usa
+foothold in that region i will continue to work closely with them in the hope of creating a new and
+more secure future
