Hence Ludlum's books continued to be published and - as is evident by The Moscow Vector and its predecessors - even survived his passing, with the able assistance of Patrick Larkin.
The Moscow Vector is in a class of its own in the series not because of the principals involved, who include the reliably competent Colonel Jon Smith - the Army doctor and virologist, and the quietly enchanting but dangerous Fiona Devlin, operating under the journalist cover. Nor the bad guys like Wulf Renke, the mad scientist whom Victor Dudarev, the President of Russia, employed to bring about the reinstitution of the Soviet Union with the involuntary involvement of the former member states.
At an international conference in Prague, Smith is contacted by a Russian colleague, Dr Valentine Petrenko. Petrenko is concerned about a small cluster of mysterious deaths in Moscow and about the Russian government's refusal to release publicly any information or data on the outbreak. When the two meet, they are attacked by a group of mysterious armed men and Petrenko is killed. His notes and medical samples are lost, and Smith barely escapes with his life.
Since the lethal bio-weapon is targeted at the US intelligence analysts, the duly-elected leaders of the former Soviet satellites and also the US president, Smith and Covert-One must quickly unravel the source of this mysterious plot. They are in a race against time, not only to prevent Dudarev from hatching his plot, but also to stop the implementation of the bio-weapon as it moves, slowly but quietly, into place in the White House.
