An excellent book which explores the close relationship between Southwell and Shakespeare. There are more verbal parallels, echoes and borrowings from Southwell by Shakespeare than from any other author, not excluding Holinshed and North (Plutarch). On the basis of John Klause's discoveries much of Shakespearean biography will have to be rewritten. I highly recommend this book to all those interested in Shakespeare's inner life.  
The book is currently out of print but is available on line here on the Sonnets web site. Click here for further details.
