The Cassandra Compact - Robert Ludlum

"What they're going to do, I never would have believed it. It's insanity!" They were the final words spoken by Yuri Danko, an officer in the medical division of Russia's security service, before his body was ripped apart by a spray of assassins' bullets. In possession of Danko's classified papers, Covert-One operative Jon Smith and CIA undercover agent Randi Russell have unearthed a terrifying global conspiracy that threatens to unleash a plague of immeasurable proportions. A Serb terrorist has been dispatched from Russia to spirit hazardous vials of deadly bacteria into the United States. His mission: deliver it to an unknown American government agent-- a shadowy figure whose own motives for acquiring the bioweapon are made all the more unfathomable when both men are found murdered, and the strain is stolen.
