Marie Wilson is an aged black woman who is nearly blind. She lives alone although is apparently well liked by neighbors. Marie's neighborhood was once family-oriented and safe but has now become blighted with crime. She lives in an urban center that shows much decay. Marie habitually carries a serrated knife with her whenever she leaves her apartment, and she has used it on one occasion to slash a would-be purse-snatcher's hand. Marie subsists on her Social Security disability payment and lives in constant fear that the Social Security people will cut her off. She knows that any disruption in payments would be financially difficult and almost impossible to rectify.
