CHAPTER XII

       The Cipher

       Table of Contents

      I went straight to my own room and commenced to work afresh on the biliteral cipher. More than ever had I the conviction upon me that the reading of the secret writing would be the first step to the attainment of my wishes regarding Marjory. It would have been strange therefore if I had not first attempted the method which she had herself suggested, the reducing the Baconian cipher to its lowest elements.

For many hours I laboured at this work, and finally when I had reduced the Baconian five symbols to three I felt that I had accomplished all that was possible in that way.2

When I had arrived at this result, and had tested its accuracy in working, I felt in a position to experiment with my new knowledge on the old number cipher. First I wrote out my method of reduction as a sort of addendum to the paper which I had prepared for Marjory. Then I made a key to cipher and one to de-cipher.3 By this time the night was well on and the grey of early morning was beginning to steal in by the edges of the blinds; I was not sleepy, however; I was too much excited to think of sleep, for the solving of the problem seemed almost within my grasp. Excited to a state which almost frightened me by its intensity, I got ready my copy of the number cipher and my newly prepared key. With an effort which took me all my resolution I went on steadily writing its proper letter under each combination without once looking back; for I knew that even should some of the letters be misplaced in the key the chance of recognising the right ones would be largely increased by seeing a considerable number of letters together.

      Then I glanced over the whole and found that many of the symbols made up letters. With such a basis to work on, the rest was only labour. A few tentative efforts and I had corrected the key to agreement with some of the combinations in the cipher.

      I found, however, that only here and there were letters revealed; try how I would, I could not piece out the intervening symbols. At last it occurred to me that there might be in the paper two or more ciphers. On trying to follow out the idea, it became apparent that there were at least a quantity of impeding numbers scattered through the cipher. These might be only put in to baffle pursuit, as I had surmised might be done when I made the cipher; or they might have a more definite purpose. At any rate they hampered my work, so I struck them out as I went along. That I continued till I had exhausted the whole list of numbers in the script.

      When I looked back over the letters translated from the cipher thus depleted, I found to my inexpressible joy that the sequence and sense were almost complete. The translation read as follows:

      “To read the history of the Trust use cipher of Fr. Bacon. The senses and the figures are less worthy than the Trinity B. de E.”

      One step more and my work was done. I set the discarded numbers in sequence on another sheet of paper, and found to my intense satisfaction they formed an inner record readable by the same key. The “encloased” words, to use Bacon’s phrase, were:

      “Treasure Cave cliff one and half degree Northe of East from outer rock.”

      Then and then only did I feel tired. The sun was well up but I tumbled into bed and was asleep in a moment.

The gong was sounding for breakfast when I awoke. After breakfast when I resumed my work I set myself to construct a variant of my number key to suit the dotted letters, for my best chance, now that I was on the track was to construct rather than to decipher. After some hard work I at last constructed a cipher on this plan.4

      I then began therefore to apply my new key to the copy of the cipher in the printed pages.

      I worked steadily and completed the whole of the first page, writing down only the answer to those combinations which fitted into my scheme, and leaving all doubtful matters blank. Then I laid aside my key, and with a beating heart glanced over the result.

      It more than satisfied me, for in the scattered letters though there were many blanks, was manifestly a connected narrative. Then I took the blanks and worked at them altering my key to suit the scheme of the original writer, till by slow degrees I had mastered the secret of the cipher construction.

      From that hour on, till I had translated the cipher writing from beginning to end I knew no rest that I could avoid. I had to take my meals, and to snatch a few hours of sleep now and again; for the labour of translation was very arduous and slow, and the strain on my eyes was too great to be kept up continuously; with each hour, however, I acquired greater facility in the work. It was the evening of the fourth day, however, before my work was complete. I was then absolute master of the writer’s intent.

      All this time I had not heard from Marjory, and this alone made excessive work a necessary anodyne. Had I not had the long and overwhelming preoccupation to keep my mind from dwelling on the never ending disappointment, I do not know what I should have done. I fully expected a letter by the last post that night. I knew Marjory was staying somewhere in the County; it was by that post that we received local letters. None came, however, and that night I spent in making a fair transcript of the whole translation.

      The first part of it was in the shape of a letter, and ran as follows:

      “My deare Sonne, These from the towne of Aberdeyne in Scotland wherin I lie sick, and before I go on my quest for the fullfillment of my Trust. I have written, from time to time during my long sickness, a full narrative of what has been; so that you may know all as though your own ears had heard and your own eyes had seen. All that I have written is to the one end—that you my eldest sonne and the rest of my children, may, should I fail—and I am weak in bodie to so strive—carry on the Trust to which I have pledged you as well as myself; so that untill that Trust be yielded up complete, neither I nor you nor they are free to any that may clash with the purpose to which our race is henceforth now devoted.
