I'm here already, in the bleak, awful hour on Dudley Flats in which the final dereliction of Elsie Williams will come to pass. I'm beginning with it, so you won't be under any illusion as to how it ends. In Blue Lake, David Sornig examines how the 8km-square zone to the west of central Melbourne became the city's blind spot. Once a fertile wetland with a large blue saltwater lagoon, it passed through various incarnations- from boneyards and rubbish tips; through the Depression-era Dudley Flats shanty town; to the modern-day docks. Through it all, one thing that has persisted is its uncanny, liminal quality. As well as being a social history and a psychogeographic contemplation, Blue Lake is a biography of three specific characters- Elsie Williams, a Bendigo-born singer of Afro-Caribbean origin; Jack Peacock, the king of Dudley Flats' tip-scavenging economy; and Lauder Heinrich Rogge, a German hermit who lived for decades with sixty dogs on a stranded ship. By charting the rises and falls in their individual fortunes, Sornig reveals much about the race and class divides of their times and explores questions about those strange and singular places in the urban fabric where chaos is difficult to contain. In masterful prose, Sornig reveals cracks in the colonial mythology of the ordered vision of progressive, urban Melbourne - a place where identities, both personal and public, have never quite been resolved. In doing so, he encourages readers to look harder at the places they live in - at the streets they walk, the buildings they enter, the empty spaces they pass - and to see in them intricate layers of time and history that have been hidden from view.
