You feel shocked and angry.
Several weeks pass.
This time you feel more alarmed, remembering the fairly recent murder of another architect. Two months later, driving home from work, your car radio tells you that police found a third architect's body along the barge canal. Few of us know prostitutes or have friends or relatives who are prostitutes. And since prostitution is generally thought of as a dangerous and despicable lifestyle, the murders of prostitutes give us some sense of insulation against these killings. But there is something else the 16 murdered prostitutes have in common besides their occupation, they were all female.
