Book Recommendation - The President is a Sick Man

I'm currently reading a very interesting book that has some similarities to the JFK assassination.  It's called "The President is a Sick Man."  It's about President Grover Cleveland.  He had a secret operation to remove a cancerous tumor in his mouth from years of smoking cigars.  The secrecy in how he was able to do this parallels the secrecy we see with JFK and his alleged Addison's disease and overall health.  Also, the roll the press played in initially have some questions and then falling in line with the official story foreshadows how they reacted to many other things, none so egregious as the no conspiracy line in the JFK assassination.
