Biblioklept

Thus Libri, who was the greatest of Biblioklepts, rescued many of the books he stole from dirt and misuse, and had them bound royally in purple and scarlet.

He loved to walk through his library, stopping before this or that special item; and, because there were biblioklepts even among the humanists in the papal employ, he kept the most precious manuscripts for greater safety in his own bedroom.

If the book's authentic, it's a national treasure! A historic find! I shouldn't wonder you'd feel a bit uncomfortable having it in your library at home in the Orchard. It's worth an absolute fortune. Every biblioklept in Britain will be bashing in the panes of your French doors.

That thief was Samuel Raynor Dupree, a novice accompanied by more experienced biblioklepts he knew only as Paul and Swede.
