Forgery only becomes visible when somebody knows enough to doubt, and the world of rare books has always drawn both the forger and the specialist who eventually notices. Joseph Hone works that territory in The Book Forger, a title announcing its subject without any embellishment at all.
Our shelving is not much of a guide in this case, so take the book on its own terms: fakes, provenance, and the peculiar economics of collectable printing, where reputation and paper turn out to be worth far more than either looks on the surface. Ten hours is the scale of a properly researched account rather than a quick anecdote, which suggests a story with enough turns in it to justify the length.
