Split personalities and secret identities have always played a major part in the characters of pulp fiction and film. They present themselves as polar opposites of what their lives truly are, which, in actuality are cold-blooded killers or hired hitmen. They must portray themselves as completely different people in order to accomplish their goal. The two lives work against each other, however, one haunting the other while the other one begins to be consumed with guilt or new feelings. The characters cannot survive with two identities and this ultimately leads to the demise of many of them. Throughout the books we have read and the films we have viewed these two-faced characters begin the story acting perfectly as the new role they have chosen, but as the novel progresses clues to their genuine nature leads to the disclosure of their true identity. In many cases the character narrating the story is also leading two lives.
This allows us to see deep inside their mind; giving us a first hand account of each of their two lives and ultimately what leads to their downfall.
