In 1917 a nun walking the unfinished Bloor Street Viaduct in Toronto is blown off the edge. Nicholas Temelcoff, a Macedonian bridge worker who swings on ropes beneath the structure, catches her one-armed in mid-air and dislocates his shoulder doing it. She abandons her habit and remakes herself as Alice Gull, while the bridge's official record keeps the commissioner and the engineering and has no place for the worker who saved her.
Official history credits a public structure to the person who commissioned or designed it, so the people whose bodies built it disappear from the record. Read any bridge, waterworks or civic monument by asking who physically made it, in what language they spoke on site, and who died doing it. The absence of their names is part of what the structure means.
For migrants and outsiders, identity works like a costume that can be put on, painted over or discarded rather than a fixed essence. Taking on a new name, language or disguise is both how the powerless survive and how they are kept unseen.
Patrick Lewis swims through the intake tunnel into the waterworks with dynamite and confronts Commissioner Harris, the man who built it. Harris does not answer with force. He talks, defends his vision, and waits until Patrick falls asleep, then spares him. The novel suggests that established power can neutralise a lone radical by listening and outlasting him more easily than by fighting him, and that one person's violence can't settle a debt owed to an entire invisible workforce.
