"When Mrs. Jack told me you were going" I answered boldly.
"Oh! I didn't mean that," she said with a slight blush "but at what time you were to be there." To which I said:
"That will be just to suit your convenience. Will you write and let me know?" She saw through my ruse of getting a letter, and smilingly held up a warning finger.
As we strolled up the road, waiting for the dog-cart to be got ready, she said to me:
"Now you can be a good comrade I know; and you said that, amongst other things, I was a good comrade. So I am; and between Braemar and Aberdeen we must both be good comrades. That and nothing more! Whatever may come after, for good or ill, that time must be kept apart."
"Agreed!" I said and felt a secret exultation as we joined Mrs. Jack. Before they started Marjory said:
"Mrs. Jack I also have asked Mr. Hunter to come on the ride from Braemar. I thought it would please him if we both asked him, since he is so diffident and unimpulsive!"
With a smile she said good-bye and waved it with her whip as they started.
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.
