The Cobra by Frederick Forsyth

The Cocaine industry is worth billions of dollars a year to the drug cartels who spread their evil seed across Western society. Its usage causes incalculable misery, poverty and death.Slowly, gradually, inexorably it is spreading...it is a blight which must be stopped. One man, Paul Devereaux, intellectual, dedicated, utterly ruthless and ex-CIA special ops, is given what seems like an impossible task. At his disposal, anything he wants – men, resources, money. He will not stop until he has completed his mission.
