Unfortunately, as the reader suspects immediately, the water contains prions that act very rapidly to destroy the brains of those who consume it. In a race against time, the WHO team and Elise Renard try to find and stop the greedy owners who don't seem to care that they are selling a very horrible death along with the water. The reader knows the major characters involved in this complex coverup, but is not fully able to separate the good guys from the bad guys until almost the very end of the novel. It moves along at a nice pace, back and forth between the settings of French provincial farms and small cities, to the cold ice of the Antarctic.
My favorite genre is the medical thriller and I read them mainly for the science and this idea of the CJD was original and well done. I knew that the doctors would save the world from drinking the contaminated water and having a massive CJD outbreak, but the story of how they solved the case was interesting and I really enjoyed it. I saw that Kalla has written another novel, Of Flesh and Blood, and I may have to read it at some point, but I'm really waiting for another with the Haldane and McLeod characters as I want to see what happens to them next!
