The first question I am asked by curious freshmen in my Shakespeare course is always, "Who wrote these plays anyway?" Now, because of Robin Williams' rigorous scholarship and artful sleuthing, Mary Sidney Herbert will forever have to be mentioned as a possible author of the Shakespeare canon. The real beauty of "Sweet Swan of Avon" is not, however, primarily academic; this book reminds of us a day when scholarship was fun, and important and original books were written for curious readers everywhere.
