Murder comes in two familiar forms. Both are heinous and most unlikely to gather any sympathy for the actual act itself from anyone, whatever the circumstances or the reasons. Whether as a crime of passion with high emotions or a cold dispassionate plot to take life in order to gain in some way, the act strikes us all as somehow inhuman. Beneath us as civilised beings. But however we cloak our animal instincts the need to remove a human being and gain relief from abuse or gain from money, the term is just the same - MURDER.Robert Louis Stevenson, Arthur Conan Doyle, J M Barrie, W W Jacobs and many others bring their literary heft to bear in as calculating a way as any killer could. Genius has many names.
