I want to know the answer to the following question:
What do the novels The Mystery of a Hansom Cab, Monkey Grip, and The Slap have in common?
All the background I'm provided with is that "Significant novels set in Melbourne include Fergus Hume's The Mystery of a Hansom Cab, Helen Garner's Monkey Grip and Christos Tsiolkas' The Slap.". Is that enough to answer the question?
