As shown in this chapter, Blackvillean crime fiction constitutes a special version of metaphysical crime fiction. It is not identical to other Postmodern types of metaphysical variations of the genre, as comparatively illustrated with Jorge Luis Borges’s short story “Death and the Compass”. The rational world that the detective thrives on is in Blackville disturbed by the forces of life itself as auto-affectivity and by constant problematisations of borders and limits on various levels. These phenomenological dimensions do not exclude rational thinking and reasoning. In addition, there are ethical questions that are dealt with alongside the epistemological issues. The concept of secrecy is also pushed to its limits and this comes out as a Janus faced force. Secrecy can be an utterly destructive energy in the way that those in power seek to utilise it in order to remain in power. As concerns amorous and sexual desires, the attempts at suppressing their forces generate suffering and pain, especially for the weaker groups in any society. The other face of secrecy is the necessity of a blank space of unknowing, since it fuels the drive of epistemology and fiction as well. A world (fictional or otherwise) completely lacking secrecy and suspense would be next to impossible to even imagine. The most prominent confirmation about a central motif in Blackville’s writing in this chapter is that Quirke’s motivation and drive towards at least temporary truths and solved cases is ontological. The energy paradoxically comes from the trauma of his childhood.
