Vladimir Nabokov 
Despair 

Self-satisfied, delighting in the many fascinating quirks of his own personality, Hermann Hermann is perhaps not to be taken too seriously. But then a chance meeting with a man he believes to be his double reveals a frightening 'split’ in Hermann’s nature. With shattering immediacy, Nabokov takes us into a deranged world, one full of an impudent, startling humour, dominated by the egotistical and scornful figure of a murderer who thinks himself an artist.
