Query: Splendid book about a sordid world

Elizabethan poet and playwright Kit Marlowe famously died in a tavern brawl arguing over the bill, or so the story goes. Nicholl shows pretty early on that it wasn't a tavern, wasn't a brawl, and probably wasn't over the bill. Then he goes into some pretty deep research to try to figure out what it probably was about.It's conspiracy theory, and like all conspiracy theory books there are some conclusions that don't necessarily follow as "obviously" or as "clearly" as the author thinks they do. (But they are at least fairly plausible -- this guy is no nutcase.) Nicholl shares so much detailed background about the sordid, sordid world of Elizabethan espionage, con artists, and political dirty tricks that the book is a gem whether you believe his ultimate Marlowe theory or not.
