How can you catch a killer you can't see? That's the question forensics expert Lincoln Rhymes faces in Jeffery Deaver's new thriller, The Coffin Dancer. The title character is one of this season's most frightening creations, a psychotic assassin who has mastered the art of blending into any environment he's in -- even a street corner swarming with cops. But what you can't see can kill you, and this psycho may be saving the last dance for Rhymes.
