I was hooked from the start. This had good bones and a lot of forensic detail that made it even creepier. I liked how Ritchie included chapters from the murderer's perspective with some slivers of his past. It was also a smooth read, with not too many twists and turns to wear you out. I did feel however that near the end, the climax was rushed and messy - like no one thought to check out all the personnel in the Hospital from the beginning? Really? A good, weekend thriller.
