The Darkness of Evil Paperback - 2017

Alan Jacobson is the national bestselling author of several critically acclaimed novels. In order to take readers behind the scenes to places they might never go, Jacobson has embedded himself in many federal agencies, including spending several years working with two senior profilers at the Federal Bureau of Investigation's vaunted Behavioral Analysis Unit in Quantico. During that time, Jacobson edited four published FBI research papers on serial offenders, attended numerous FBI training courses, worked with the head firearms instructor at the academy, and received ongoing personalized instruction on serial killers--which continues to this day. He has also worked with high-ranking members of the Drug Enforcement Administration, the US Marshals Service, the New York Police Department, SWAT teams, local bomb squads, branches of the US military, chief superintendents and detective sergeants at Scotland Yard, criminals, armorers, helicopter pilots, chief executive officers, historians, and Special Forces operators. These experiences have helped him to create gripping, realistic stories and characters. His series protagonist, FBI profiler Karen Vail, resonates with both female and male readers, and writers such as Nelson DeMille, James Patterson, and Michael Connelly have called Vail one of the most compelling heroes in suspense fiction.

Jacobson's books have been published internationally, and several have been optioned for film and television. A number have been named to Best of the Year lists.

Jacobson has been interviewed extensively on television and radio, including on CNN, NPR, and multiple ABC, CBS, NBC, and Fox network affiliates.
