Western biofiction narrative is a literary genre in which a historical personae’s life is presented through narrative devices of fictionalization based on narrative imperatives of his/her biomemes. As the main characters of “disputes over authorship”, Christopher Marlow and William Shakespeare frequently appear in recent western biographies and biofiction narratives. Integrating both academic and detective elements, Steven Duggan reconstructs, in The Case Of The Dead Dane: A Marlowe and Will Mystery, the creation process of Hamlet in the form of biofictions instead of academic works, thus creating an alternative collusion hypothesis. To certain extent, The Case of the Dead Dane represents the new trends of postmodern biofictional narratives, namely, academicalisation, alternativisation and unnaturalisation.
