I recently read Plum Island, a novel by Nelson De Mille (2011).
An NYPD detective, John Corey, is convalescing in a rural Long Island area after being shot in the line of duty. During his recovery he is befriended by a young couple of Ph.Ds who work at the federal research facility on Plum Island. The focus of that facility is on animal diseases, but it has long been suspected of also being involved in germ warfare research.
When the young couple is murdered, Corey gets invited into the investigation by local law enforcement. The story takes off from there. More murders, more intrigue, pirate treasure, a hurricane, romance. A little something for everyone.
Love De Mille.
