Black Rock White City (Melville House, £16.99) is ostensibly about a spate of sinister graffiti in a Melbourne hospital. ‘The Trojan Flea’ is scrawled across X-ray screens; ‘I am so full of your death I can now only breathe your rot’ on a stairwell; and, on a dead body, ‘cut into the flesh with a scalpel, from throat to navel, is the word INSPIRATION’.
