Nothing could be worse for the work of mourning, than confusion or doubt: one has to know who is buried and where', writes Jacques Derrida in Spectres of Marx. This paper offers a reading of Charlotte Brontë's Villette and its depiction of haunting, letters and desire through the context of M. Paul's uncertain death at the end of the novel. Using Derrida's notion of spectral ambiguity and the impossibility of knowledge posed by the ghost, I situate the obfuscation of M. Paul's death as a primal scene informing upon the text as a whole; offering a hindsight which underwrites Lucy Snowe's fixation with the perpetual frustrations and losses of erotic desire. I would suggest that this sense of bereavement manifests itself in Lucy's repeated correlation between letters and haunting, and the shared syntax of desire through which she interprets the lacuna permeating both. To Lucy, letters come to stand in the place of bodies and this misreading of the displaced Other prefigures her response to the 'ghost' nun. Both letters and the ghost thus become dialectical in creating the traffic of confused readings instigated by M. Paul's forever absent body, and the haunted 'counter-knowledge' fixed by the text's ultimate, final recalcitrance to pronounce dead or alive.
