NEW YORK TIMES BESTSELLER • A sinister act of bioterrorism spreads a deadly epidemic across America in this “spine-tingling” (Denver Post) novel from the “master of the medical thriller” (The New York Times).
 
After he loses first his midwestern ophthalmology practice to a for-profit medical giant and then his family to a commuter airline tragedy, Dr. John Stapleton’s life is transformed to ashes. Feeling less the golden boy than a jaded cynic, Stapleton retrains in forensic pathology and relocates to find an uneasy niche for himself that suits his changed perspective: the cold, indifferent, concrete maze of New York.
 
Stapleton thinks he is past pain and past caring, but as a series if virulent and extremely lethal illnesses—capped by a particularly deadly outbreak of a rare strain of influenza—strikes the young, the old, and the innocent, his suspicions are aroused. When the apparent epicenters of these outbreaks are revealed to be hospitals and clinics controlled by the same for-profit giants that cannibalized his old ophthalmology practice, Stapleton fears he has stumbled upon a diabolic conspiracy of catastrophic proportions: Could the for-profit giant be engaged in the systemic elimination of its more costly subscribers?
 
Getting to the truth leads to Stapleton’s unlikely pairing—both professionally and personally—with Terese Hagen, an art director at a hot Madison Avenue advertising firm. Together they discover that the real explanation behind the killer contagions is even more Machiavellian than could be imagined.
