Robert Ludlum's the Cassandra Compact

"What they're going to do, I would never have believed it. It's insanity!" They were the last 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 assassin's bullets. Now Covert-One's Jon Smith has Danko's classified papers, and he's unearthed a terrifying global conspiracy. A Serb terrorist has been despatched from Russia to smuggle hazardous vials of a deadly bacteria into the United States. His mission was to deliver them to an unknown US government agent. Then both men are murdered, and the deadly bacteria is stolen ...It's up to Lt Col Smith to find the madman who possesses it, before he holds a defenseless world hostage with the power to render the human race extinct.
