So wrote John le Carré in the afterword to his eighteenth novel The Constant Gardener which was made into a very powerful movie in 2005.
Of course, John le Carré is best known for his espionage novels. Who hasn't read The Spy Who Came in from the Cold and Tinker Tailor Soldier Spy, to name just two?
His book The Constant Gardener - and the movie of the same name - are a frightening exposé of the drug trials carried out by the big pharmaceutical companies on innocent people in Africa.
John Le Carré once said, "Having your book turned into a movie is like seeing your oxen turned into bouillon cubes." This movie is a very well-made bouillon cube.
