The Great Arch has considerable if unlikely charm. It is a history of the building of the Sydney Harbour Bridge in a novel about real and imagined people living near its construction site. Hastrich brings to life (potentially dry) detail about huge steel plates, creeping cranes, rivets and cables. We see this mostly in the writings and photographs of her central character, an Anglican vicar who records the progress of the bridge-building in his parish paper and also writes a two-volume book about it. The Reverend Ralph Anderson Cage, rector at St Christopher’s at Lavender Bay (based on a real person, Frank Cash), is an endearingly hapless yet decent man who becomes obsessed with the unfolding engineering marvel that reshapes the population and topography of his once-thriving parish.
