This return engagement for quadriplegic criminologist Lincoln Rhyme is strong on forensic details as Rhyme tracks an elusive assassin known only by the tattoo that gives this fast-paced thriller its title. Three witnesses to a murder could put a millionaire arms dealer behind bars for good. When one of them, the co-owner of Hudson Air, is blown up in a plane bombing with the Dancer's fingerprints all over it, the FBI takes the other witnesses into protective custody. Only Rhyme can decipher a crime scene, read the residue of a bombing, or identify a handful of dirt well enough to keep up with the killer.
