The First Patient / Michael Palmer / 371 pages

The author, Michael Palmer, is known for his medical mysteries.  This is the first one I have read and I enjoyed it.  Andrew Stoddard is the President of the United States and has been experiencing unexplained psychotic episodes.  His personal physician suddenly and mysteriously disappears.  The President convinces his Naval Academy roommate, Gabe Singleton, who is now a doctor to come to Washington to become his personal physician.  It is only after taking the job and coming to the White House that Gabe learns about the president's condition.  The President needs Gabe to figure out what is causing these episodes.  There is a lot of excitement, action, and danger as Gabe works to help his long time friend.
