Gears to Riches: Story Of Success And Tragedy

In the world of the Mafia, you can't trust anyone.
In the future, life is uncertain.
In steampunk, you don't know if it will work

Not good with words
Wrong place wrong time

What if from one of McKenzie's mistakes changed him from fighting detective to new head of the Mafia? From a mechanical mishap and appearance change, soon McKenzie went from detective to an agent to spy on The Jungle; one of the most influential crime syndicate to date. Will the weight of guilt and pressure on him, can he take the heat? Or will he malfunction under command?
