I fear that logic, as understood in books, had little to do with my kiss on reading this; the reasoning belonged to that higher plane of thought on which rests the happiness of men and women in this world and the next. There was not a thought in the postscript which did not give me joy--utter and unspeakable joy; and the more I thought of it and the oftener I read it the more it seemed to satisfy some aching void in my heart, "Have you deciphered the papers"--the papers whose existence was only known to her and me! It was delightful that we should know so much of a secret in common. She had been 'thinking over them'--and other things! 'Other things!'--I had been thinking of other things; thinking of them so often that every detail of their being or happening was photographed not only on my memory but seemingly on my very soul. And of all these 'other things' there was one!!... To see her again; to hear her voice; to look in her eyes; to see her lips move and watch each varying expression which might pass across that lovely face, evoked by thoughts which we should hold in common; to touch her hand.... I sat for a while like one in a rapturous dream, where one sees all the hopes of the heart fulfilled in completeness and endlessly. And this was all to be on Tuesday next--Only six days off!... I started impulsively and went to the oak chest which stood in the corner of my room and took out the papers. After looking over them carefully I settled quietly down to a minute examination of them. I felt instinctively that my mandate or commission was to see if they contained any secret writing. The letters I placed aside, for the present at any rate. They were transparently simple and written in a flowing hand which made anything like the necessary elaboration impossible. I knew something of secret writing, for such had in my boyhood been a favourite amusement with me. At one time I had been an invalid for a considerable period and had taken from my father's library a book by Bishop Wilkins, the brother-in-law of Oliver Cromwell, called "Mercury: or the Secret and Swift Messenger." Herein were given accounts of many of the old methods of secret communication, ciphers, string writing, hidden meanings, and many of the mechanical devices employed in an age when the correspondence of ambassadors, spies and secret agents was mainly conducted by such means. This experience had set my mind somewhat on secret writing, and ever after when in the course of miscellaneous reading I came across anything relating to the subject I made a note of it. I now looked over the papers to see if I could find traces of any of the methods with which I was acquainted; before long I had an idea.
