query: What was Alan Jacobson's first published book?
passage: Alan Jacobson (writer)
Twenty years later, in the early stages of his writing career, Jacobson realized the professor had a point. If you were going to write about something like war and abdominal wounds, you needed to know what you were talking about.[17] While writing his first published novel, False Accusations, his path crossed that of the head of the California Department of Justice. During a phone call with Jacobson, he requested a reference on one of Jacobson's employees who was applying to be a forensic scientist. Jacobson then asked the director a question about a novel he was writing (False Accusations) involving the character of Ryan Chandler.[18]
passage: Alan Jacobson (writer)
Jacobson has become known as a novelist who heavily researches his books. During his twenty-five year career, Jacobson has embedded himself with law enforcement officers across a range of agencies, including several years with the FBI's Behavioral Analysis Unit in Quantico; the DEA, US Marshals Service, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the NYPD, SWAT, and local bomb squads. He has also worked extensively with the US military, Scotland Yard, criminals, armorers, helicopter and fighter pilots, CEOs, historians, combat surgeons, astronauts, rocket scientists, and Navy SEALs.[42] He said that working with the agents, detectives, and officers allows him to go behind the scenes, ask them questions, see them in their environment, and try out their equipment. Hearing their stories, seeing how they approach different scenarios, sitting in their labs or tactical vehicles, observing them handling criminals and running investigations are the things he takes back with him to the keyboard when writing his novels.
