Read it through once

I shut it, and took up another and another, till I had examined all. Catherine’s library was select, and its state of dilapidation proved it to have been well used, though not altogether for a legitimate purpose: scarcely one chapter had escaped a pen-and-ink commentary—at least the appearance of one—covering every morsel of blank that the printer had left. Some were detached sentences; other parts took the form of a regular diary, scrawled in an unformed, childish hand. At the top of an extra page (quite a treasure, probably, when first lighted on) I was greatly amused to behold an excellent caricature of my friend Joseph,—rudely, yet powerfully sketched. An immediate interest kindled within me for the unknown Catherine, and I began forthwith to decipher her faded hieroglyphics.
