Who is Killing the Great Capes of Heropa?

Heropa: A vast, homogenized city patrolled by heroes and populated by adoring masses. A pulp fiction fortress of solitude for crime-fighting team the Equalizers, led by new recruit Southern Cross - a lifetime away from the rain-drenched, dystopic metropolis of Melbourne. Who, then, is killing the great Capes of Heropa? In this paired homage to detective noir from the 1940s and the "60s Marvel age of trail-blazing comic books, Andrez Bergen gloriously redefines the mild-mannered superhero novel.
