Pill-popping, non-English speaking illegal aliens with super hearing. Derivative trading gone right. A vertigo-suffering former worker, now anonymous extortionist. The older brother and his unaware clone....
Subway Noise begins in near future New York City with Oscar Witz III trading derivatives using a novel surveillance operation. Non-English speaking illegal aliens ingest auditory-enhancement pills, then repeat nearby Wall Street strategy sessions.
Silent on the probability of the auditory pill's long-term effects, Oscar receives an extortion letter from an anonymous ex-repeater suffering vertigo.
What to do? Oscar ponders the future and recalls a family secret. He has a cloned brother, who he has never met. This brother, Seaver, now college age, was born in vitro to a woman unaware of any cloning process during her pregnancy.
Soon, Seaver is interning at Oscar's lab...always leaving alone... at night.
