Viral : an international thriller
(Book)

Subtitle from dustjacket.

A deadly virus is sweeping through through the Third World with frightening speed and potency. A three-word message in a Washington, D.C. safe-deposit box may be the key to stopping it--if Charles Mallory, a private intelligence contractor and former CIA operative, can decipher the puzzle before time runs out. As he and his brother Jon, an investigative reporter, begin to uncover traces of a secret war, with the goal of creating a technologically advanced society--via a planned "humane depopulation"--they find themselves caught up in a complex game of wits with a brilliant, elusive tactician who believes that ends justify means. --Adapted from Amazon.com summary.
