Wu Song
Wu Song grows suspicious of his brother's death. He carries out his own investigations and discovers the truth. In "Water Margin", Wu Song's slaying of the adulterous pair is described in graphic detail and is one of the most memorable scenes in the novel. In "Jin Ping Mei", however, Pan Jinlian marries Ximen Qing as a concubine, and Wu Song kills Pan after Ximen dies from excessive sexual activity.
