The similarities between Molloy and Moran appear innumerable. To name a few, Moran finds himself in need of crutches just as Molloy. He murders a man in a similar nature to Molloy's act of murder, and both follow the command of a voice whose origins are unknown. Initially I felt Molloy and Malone were one, which they very well may be, but the more I read the more I picked up on the 'criminal/detective mindset'.
I can see myself watching a black and white crime type movie while reading Molloy. The elusive criminal boggles the mind of the detective who vehemently puffs on his cigar, billowing smoke about the local bar he's gone into for information. The criminal and detective have a unique, intertwined relationship, but never meet. The criminal drives himself mad due to paranoia of capture. He must outwith the detective. The detective in turn must outwit the criminal in order to capture him, but neither can complete their goal without studying the other and thinking as if they are in the others position. The criminal must become the detective and the detective the criminal. The two play out these reverse roles so well that they drive themselves mad, losing their sense of self, sinking into insanity.
This is the theme that oozes from Molloy. The piece is 'Cops and Robers' gone mad, lost in the world of Beckett, left to his beautiful mutilating devices.
