This story begins by reporting the deaths of six women by a person known as the Viaduct Killer,
the place where the victims were found. But then Peter Straub launches into what appears to be the description of a city, one that might appear in a travel book.
At first it seems like an ordinary Midwestern city with the typical harsh winters, a vaguely incompetent mayor, the usual distribution of housing, classes, schools, political parties. But gradually we descend into a much more ominous landscape where feral children roam, where ethnic groups clash, where wolves, raised for unknown reasons, by one generation, still exist. More and more we find traditions, creatures, habits that seem frightening or fantastical. There is a unfinished bridge that no seems to find unusual.
Straub's descriptions are so well done, alternating the real with the surreal that we willingly follow him along. The story succeeds on the evocation of an atmosphere rather than any specific plot. The horror is palpable if somewhat vague.
In an interview Straub says that he wanted to take his native city of Milwaukee, and exaggerate its weaknesses to the point of horror.
