This is the third book in the series. After Sandford was somewhat disappointed in his second book, he says his friend Stephen King told him, "Sometimes you just have to gross 'em out." And Sandford does. This a compelling page-turner featuring one of the nastiest villains in crime fiction. His inherent evil mixed with an insane cocktail of drugs (he's a doctor and can get any drug he wants) makes him unpredictable and horrifyingly dangerous. This is actually my favorite installment in the series. Sandford's writing is tight and his descriptions always spot on. This is John Sandford at his best.
