Why is it that we are so fascinated by conspiracy theories? From speculation about who really killed JFK (or assertions that he is still alive) -- to UFO's -- to the President Bush's supposed lying about what he knew to get us into a war with Iraq -- books and "documentaries" and Blogs abound trying to "prove" that what really happened is being "covered up." Certainly it is one of the founding principles of this country that we have the right to "get to the truth." Sam Adams wrote, "The public cannot be too curious concerning the characters of public men."1
But there is a difference between "muck-raking" (actively looking for the worst to report) and honest reporting of the truth. One begins with negative ad hominem assumptions and attempts to prove those assumptions. The other seeks the truth and (as much as humanly possible) reports the findings without prejudice. There is a difference in stating someone is evil and trying to prove it and reporting the facts and letting the reader decide.
That is why Kathryn Lindskoog's book, The C. S. Lewis Hoax (1988, Multnomah Press), was unexpectedly refreshing. Rather than make assumptions about the character of Walter Hooper (and others assigned to the stewardship of Lewis's work after his death), Lindskoog simply presents the facts that she has discovered and leaves the conclusions (mostly) to the reader. This is one book any serious student of Lewis cannot be without.
Kathryn Lindskoog was a Lewis scholar from 1954, when she was an undergraduate student at the University of Redlands in California, until her death from MS in 2003. Her biography, C. S. Lewis: Mere Christian, was first published in 1973, which is probably her most famous book. She has written several other volumes about C. S. Lewis, prose versions of Dante's Divine Comedy, and a series of classic fiction edited for young readers. There is a web site with more information on her life and works: http://www.lindentree.org/.
