I can guess the remainder of your story now.

You carried this news to the Baron de Carjorac, and he, breaking down, confessed to you that he had lost something." "Yes, yes--a dreadful 'something,' Mr.Cleek: the horrible thing that has been making life an agony to him ever since.

On the night when that abominable 'Red Crawl' first overcame him, there was upon his person a most important document--a rough draft of the maps of fortification and the plan of the secret defences of France, the identical document from which was afterwards transcribed the parchment now deposited in the secret archives of the Republic.

When Baron de Carjorac recovered his senses after his horrifying experience--" "That document was gone ?" "Part of it, Mr.Cleek--thank God, only a part! If it had been the parchment itself, no such merciful thing could possibly have happened.
But the paper was old, much folding and handling had worn the creases through, and when, in his haste, the secret robber grabbed it, whilst that loathsome creature held the old man down, it parted directly down the middle, and he got only a vertical section of each of its many pages." "Victoria! 'And the fool hath said in his heart, There is no God,'" quoted Cleek.

"So, then, the hirelings of the enemy have only got half what they are after; and, as no single sentence can be complete upon a paper torn like that, nothing can be made of it until the other half is secured, and--our German friends are still 'up a gum-tree.' I know now why the baron stayed on at the Chateau Larouge, and why 'The Red Crawl' is preparing to pay him another visit to-night: he hoped, poor chap, to find a clue to the whereabouts of the fragment he had lost; and that thing is after the fragment he still retains.
