Plum Island is a fictional novel about a convalescing New York Police homicide detective named John Corey, who gets involved in a multiple murder investigation while he is supposed to be recovering from serious wounds. John is originally working as a consultant for the small township, where an old friend of his is the Chief of Police, but when he is relieved of this position, he continues the investigation on his own. Eventually the county detective assigned to solve the case, Beth Penrose, invites him to collaborate with her and the team solves the original double murder, and all of the murders committed by the same man, Frederic Tobin. John Corey is relaxing on his Uncle Harry's deck when Sylvester Maxwell, Chief of the local police, asks John to accompany him to the murder scene. Tom and Judy Gordon, biologists at the nearby Plum Island biological animal research center, and recent friends of John, have both been shot in the head on the deck of their home. John meets Detective Beth Penrose of the Suffolk County Sheriff's Office, Foster of the FBI, and a man named Ted Nash who says he is from the Department of Agriculture but turns out to be a CIA agent. The initial investigation focuses on the Gordons stealing a virus from the Plum Island facility and selling it to a foreign government. To this end, the team of Nash, Foster, John, Beth and Max are taken on a lengthy tour of the facility, including the uninhabited part of the island that contains a revolutionary war era abandoned fort. While on the tour, John and the team meet the head of security, Paul Stevens. They also learn that the Gordons were involved in researching a vaccine for Ebola, were amateur archeologists, and had free reign to bring their boat to and from work ... ... John and Beth take Tobin's boat to the ferry dock and Max meets them there. John heads for Manhattan to face the wrath of his NYPD supervisor. At his home, he finds a letter from the Gordons, written before their murder, verifying everything he has now discovered. John goes to meet with his supervisors and negotiate a way out of the trouble he is in for disobeying orders. The last chapter shows John teaching homicide investigation, as a retired police officer. It is several months after the Plum Island incident, and he misses the police force, but accepts what needed to happen. He is also unattached. John is surprised to se that Beth Penrose has enrolled in his class. She catches him up on the latest from Suffolk County, and is gently offering to be in his life again. While he initially resists, he announces to the class that he is taking her for drinks that night.
