The Encyclopedia of Genocide and Crimes Against Humanity, an amazing set by MacMillan Reference USA
here's a review
Coverage is not limited to the modern era, but includes discussions of Rome's treatment of Carthage, the campaigns of Genghis Khan, the Spanish Inquisition and the Atlantic slave trade. Other essays examine the question of whether the definition of genocide applies to the forced removal of Native Americans or the dropping of the atomic bomb on Hiroshima. Also explored is the susceptibility to abuse of such groups as women, children, homosexuals or the disabled. Finally, other scholars explore the sociology and psychology of victims, perpetrators and survivors. From the Supreme Court decision on the Amistad slave captives to the prosecution of Serbian war criminals, a selection of historical documents trace the extension of protections to civilian populations in international law. Though scholarly in its approach, this set is highly recommended for high school, academic and public libraries."

It is ridiculous to set a detective story in New York City. New York City is itself a detective story...
