John Harris and Richard Wilbourn have been researching the Rudolf Hess case since 1987, shortly after Hess died in Spandau, Berlin. Since then they have written five authorative books on the Hess flight and mystery. Their professional disciplines and varied mix of skills and interests have been extremely pertinent when addressing the various issues relevant to the Hess affair. When not so engaged, they have full time employments; Harris as a Chartered Accountant in Northamptonshire and Wilbourn a farms manager on a large Norfolk estate. Over the past 25 years they have made some major discoveries pertaining to the Hess affair and now are regularly quoted as reliable sources by others.
