Cemetery Dance, Paperback Book, By: Douglas Preston

FBI Special Agent Aloysius Pendergast recently returned to New York and Lieutenant Vincent d'Agosta find themselves investigating the murder of a friend when reporter William Smithback and his wife Nora are brutally attacked in their apartment. The assailant is identified by eyewitnesses as their strange, sinister neighbour a man who, by all accounts, died ten days earlier. Shunning the official inquiry, Pendergast and d'Agosta undertake their own private and unorthodox quest for the truth. Their journey takes them deep into the dark and mysterious underbelly of Manhattan, to a secretive, reclusive cult of Obeah and voodoo which no outsiders have ever survived.
