Blow Fly is an engaging, well-crafted story that lures you with a series of chilling incidents. Never one to shrink from disturbing material, Cornwell does a particularly fine job of fleshing out her villains — a cruel, depraved, and thoroughly intriguing cast of characters who keep the action moving at a steady pace. This powerful entry in the Scarpetta canon mesmerizes with its unflinching glimpse into the darkest depths of the human heart.
