No, this is not a Wall Street saga of government bailouts and astronomical bonuses. It is a dull review of a work of fiction.
As such the plot is fairly common place, and a similar tale could have been told in the setting of any multi-national corporation. Why banking?
Then again, where as the narrative is well paced, the characterisation is weak. A more skilled novelist might have been able to make the characters more true to life. As such they lack depth and complexity. The polarisation of the two main protagonists as paragons of virtue and weakness respectively is too simplistically black and white. So where as the basic idea of the novel has potential, the way it has developed doesn't do it justice. In the hands of a Jeffrey Archer or a Sidney Sheldon - better still a Jhumpa Lahiri or a Vikram Sheth - this novel could have been memorable work of modern fiction, perhaps even a master-piece.
Yet for a first novel and from the pen of one who is not a professional writer - this could have been worse. In fact, I see in it the seeds of a fairly decent Bollywood flick! Ram Gopal Verma, Madhur Bhandarkar, Ashutosh Gowarikar - are you people listening?
