I don't usually read much crime fiction, but if Glen Duncan writes a crime novel, I'm in. His writing is delightful on every level. It's clever and philosophical without being didactic or allowing its intellect to obscure the edge-of-your-seat thrills. His characters are wonderfully, tenderly, realistically drawn, which make the moments of human brutality in this book even more terrifying. His pacing is spectacular - I haven't been so gripped by a book for a very long time. Go read this book right now, and don't come up for air until you've finished - you won't want to.
