Sioux City is linked to Calvin Evans’s childhood in a boys’ home, making the city an important clue to the institutional past he left behind. The novel gives little description of Sioux City itself; its significance comes through the home, the records connected to it, and the effort to identify where Calvin grew up.

Association with Calvin’s Childhood

Calvin Evans is described as having grown up in a boys’ home in Sioux City, an institution with religious overtones. The home’s appeal for donations, associated with All Saints Boys Home, recalls that a former donor had supported scientific educational opportunities and healthy outdoor activities for its residents. The appeal suggests that the home depended on outside support and had lost its principal donor.

A Clue Recovered from the Trash

The connection between Calvin and Sioux City emerges through a discarded letter. Madeline finds a piece of paper wadded into Calvin’s trash and retrieves it; the letter asks him, as a former resident, to contribute to the home. His own response is discarded there too, and its furious rejection of the institution sharply contrasts with the appeal’s account of its past educational and recreational support.

The City as an Inference

In a later conversation about locating the boys’ home, the librarian points out that Iowa is too large to identify a place from the limited information available. Reverend Wakely proposes Sioux City as the likely answer. The suggestion turns the city into a narrowing clue in the search for Calvin’s origins, while the earlier letter supplies the stronger connection between Sioux City and his childhood.
