The Hades Factor - Robert Ludlum

Hades is the hame of a seemingly unbeatable doomsday virus. For three frantic days, scientists in a US government laboratory have been trying to unlock the virus’s secrets as people across the continent die in excruciating agony.

Lt. Col. Jonathan Smith, MD, is a career soldier with intelligence training. Summoned to a clandestine meeting with his oldest friend, an FBI agent, Smith is attacked. But he escapes only to find the woman he loves  is also dying of a virus: Convinced she was murdered Smith turns rogue to find the killer. With the help of  a beautiful CIA agent, he uncovers a horrifying plot to infect millions with a deadly pandemic.

From London to Californía, Washington to Iraq, Smith risks everything against a powerful corporation, the US government and army, and a determined genius out to destroy his efforts at any cost while the world is held to ransom for billions of dollars.
