This thesis explores the representations of violence and urban space in Lawrence Block’s hard-boiled detective novels. With critical analysis of representative Scudder novels, I contend that while employing the hard-boiled writing style Block takes on a great challenge to define violence, an essential element of hard-boiled world that has been presented as indefinable. He attempts to see beyond the boundary of morality while exploring the alternative functions and purposes of violence. Meanwhile, by varying violent behaviors in the context of contemporary New York, Block loads them with social significance, manipulating representations of violence as response or commentary on the society. However, while proposing Block’s achievements in genre writing as well as social critique, I discuss his limits and failures, some of which are due to Block’s own bias while others stem from inherent instability of the violence motif itself.
