Then, with my heart beating wildly, I turned to decipher the document, but even then I found it useless. Indeed, I spent the remainder of that night in vainly trying to solve the puzzle.

That same afternoon I went to Staffurth’s, told him of my inspiration, and showed him my alphabet. Adjusting his big spectacles, he regarded it for a long time in silence, but I saw that, to him, mine was a new and rather striking idea. He took a sheet of paper and tried time after time to make sense of that first long line of bewildering capitals, acting upon the supposition that three was the number.

Suddenly the old man cried excitedly, turning to me —

“I’ve got it! At last! See! The golden number is three. Your alphabet is the correct one, only the letters are reversed three by three. Take these first six, and then reverse them. You have SP HXWE, which by aid of your alphabet reads: ‘On thys’——The Secret, whatever it is, is ours—ours!”

CHAPTER XXXIII
WE DECIPHER THE PARCHMENT

Our excitement over the discovery was unbounded. Old Mr. Staffurth’s announcement seemed hardly possible. His hand trembled as he held the paper whereon I had copied the precious document catalogued among the Oblata Rolls, while I, bending over him, stood eager but speechless.

“See!” he cried. “The cipher is cunningly reversed, in order to make it more complicated. The big threes written by the old Italian were drawn as a silent indication of the correct solution of this document. Besides, there is before and after the entry of the date of the document two threes, one at each end—meaning first the third letter, and secondly each three letters reversed.”

“Let’s decipher it at once—whatever it is!” I exclaimed, hastily pulling up a chair to the table beside him and taking a sheet of blank paper and pencil. Imagine for yourself the tension of my mind at that critical moment. What might not be concealed behind that bewildering array of letters? Was the secret of the whereabouts of the treasure written there, or was it, after all, only some unimportant record having no reference at all to the hidden loot?
