Lincoln Rhyme #6, The Twelfth Card by Jeffery Deaver (2005)

Bestselling master of suspense Jeffery Deaver is back with a brand-new Lincoln Rhyme thriller. To save the life of a young girl who's being stalked by a ruthless hit man, Lincoln and his protege, Amelia Sachs, are called upon to do the impossible: solve a truly "cold case" -- one that's 140 years old."The Twelfth Card" is a two-day cat-and-mouse chase through the streets of uptown Manhattan as quadriplegic detective Lincoln Rhyme and Amelia Sachs try to outguess Thompson Boyd -- by all appearances a nondescript, innocuous man, but one whose past has turned him into a killing machine as unfeeling and cunning as a wolf. Boyd is after Geneva Settle, a high school girl from Harlem, and it's up to Lincoln and Amelia to figure out why.The motive may have to do with a term paper that Geneva is writing about her ancestor, Charles Singleton, a former slave. A teacher and farmer in New York State, Charles was active in the early civil rights movement but was arrested for theft and disgraced. Ass
