Wittgenstein's Mistress is a novel unlike anything David Markson or anyone else has ever written before. It is the story of a woman who is convinced and, astonishingly, will ultimately convince the reader as well that she is the only person left on earth. Presumably she is mad. And yet so appealing is her character, and so witty and seductive her narrative voice, that we will follow her hypnotically as she unloads the intellectual baggage of a lifetime in a series of irreverent meditations on everything and everybody from Brahms to sex to Heidegger to Helen of Troy. And as she contemplates aspects of the troubled past which have brought her to her present state―obviously a metaphor for ultimate loneliness―so too will her drama become one of the few certifiably original fictions of our time.
