This is an easily readable and short life of Shakespeare written for a series called "Eminent Lives" and strangely coming after books on George Balanchine and George Crick!! In it Bill Bryson, in his inimitable witty style, tells us how little is known of WS's life but then goes on to examine what others have conjectured about it, pouring scorn on so many of the theories. I have read several attempts at Shakespeare biographies but still learned something from this [especially on the Bard's neologisms] but my favourite was the final debunking of the attempts to say the plays were written by someone else. Bryson does this so amusingly [can it be true that of the 5000 books written to prove Shakespeare's plays were written by someone other than Shakespeare, three were by Messers Looney, Silliman and Battey?!] that I was actually laughing as I read it. For example, on the claims for Marlowe to have been the real Shakespeare, Bryson writes "He was the right age ..., had the requisite talent and would certainly have had ample leisure after 1593, assuming he wasn't too dead to work."
So, Bryson has produced just what his publishers wanted, a brief biography that anyone can read and learn from, which appears both learned and well researched on the one hand, but also enjoyable and amusing on the other.
