This book turned around my sagging reading life in October: I read 400 pages in a day while camping! I enjoyed the mystery aspect, which begins when a mentally ill man bursts into Cormoran's office raving about a murder he witnessed as a child. But my real interest in this fourth novel lay in the personal lives of the detectives, especially after book three's cliffhanger ending. (Sensitive readers will want to know that <em>Lethal White</em> is much less gruesome than books two and three. It's intense, but not gory or graphic.) An altogether satisfying addition to the series. Robert Glenister's narration was fantastic, even though I switched to the hardcover so as to get to the ending faster.
