Robert Ludlum's The Paris Option

A fiery explosion shatters a laboratory building in Paris. Among the dead is Emile Chambord, one of the leaders in the global race to create a molecular - or DNA - computer. Unfortunately, Professor Chambord kept the details of his work secret, and his notes were apparently destroyed in the fire.

This is not the work of a clever hacker - only the enormous power and speed of a DNA computer could have caused such havoc. Covert-One agent Jon Smith flies to Paris to investigate. Following a trail that leads him across two continents, he uncovers a web of deception that threatens to re-shape the world for ever...
