Street to Street is one of Brian Castro’s best books yet, a comic-tragic enactment of the anxieties of the writing life, in which the early twentieth-century Sydney poet Christopher Brennan plays a major role. Castro’s double portrait of the poet and his biographer, the writer-academic Brendan Costa, plays on the disappointment, the guilt, the lack of recognition, which troubles those who live by their imaginations. The novella is the perfect form for Castro’s purpose, its compression heightening the wit and energy of his prose, and his remarkable feel for the embarrassments of character.
