Whodunnit v: Introductory theory

So many people have testified, given statements, and written books about the assassination of John F. Kennedy that someone writing another almost finds himself, like a novelist, with everything within the limits of his imagination to draw from. For such an author, the plot he elects to track and the characters with which he carries it to fullness will not only shape how readers will regard his work but reveal something about his thought processes and motivations in writing it.
Some books with the germ of an idea, an observation, an area of inquiry and develop as research and thought takes them. In others the course is set in advance, and the only details that are applied are those which fit the route which has already been mapped out.
Some of these choices make a work compelling.
Others throw it out of whack.
So with that in mind, stay tuned.
