Speculation about Shakespeare – who he was, what he did, even whether he really existed – has become a profitable literary subgenre, with new books constantly being released to propound ever more unbelievable theories of the Bard, and others written expressly to dismiss such pie-in-the-sky ideas. It’s actually become difficult for a casual reader to find a straight-ahead, informative, and engaging biography of the playwright, in the same way that it is hard to find a book featuring an objective dissection of American foreign policy under George W. Bush. But “amid all this specialized debate, there is also a steady flow of less agitated books intended for the general reader, including three particularly insightful and well-written ones in the last year or so.”
