Greg Ahlgren is a criminal defense lawyer in Manchester, New Hampshire. He received his B.A. degree from Syracuse University and his J.D. from the University of Pennsylvania. He has been a criminal justice professor, a state legislator, and a political activist, and has appeared as a frequent guest on both national and local television and radio shows on true crime and historical issues. His books include the alternative history time-travel novel "Prologue" and the international thriller "The Medici Legacy," and along with Stephen Monier he co-authored the true crime book "Crime of the Century: The Lindbergh Kidnapping Hoax."
Prior to "Crime of the Century's" publication, most commentators on America's most famous crime had questioned Hauptmann's guilt, but had been unable to offer a cogent alternative hypothesis. Combining their respective expertise as a criminal defense lawyer and a seasoned police investigator, Ahlgren and Monier were the first to theorize that perhaps there had been no stranger abduction and that the "kidnapping" had been hastily concocted to mask a domestic tragedy. Controversial at the time of original publication, this theory has now gained widespread acceptance as a plausible explanation of the Crime of the Century.
In his novel "Prologue," Ahlgren inverted the usual time-travel plot line. Instead of creating protagonists intent on preserving a recognized time line from attack by those seeking to change history, Ahlgren devised an alternative future, and then, set against the backdrop of the JFK assassination, presented his protagonists with the challenge of creating a better today.
His novel, "The Medici Legacy," utilized a plot convention rare in an American thriller when Ahlgren created a non-American chief protagonist, Deputy Inspector Antonio Ferrara of the Italian Polizia di Stato.
In an interview, when asked to name two fiction writers, one past, one present, who have influenced his writing, Ahlgren named Daphne duMaurier and Tim Green.
In a pretentious law school alumni questionnaire, when asked to list his greatest personal or professional achievement, he reportedly scribbled, "never, ever having voted Republican."
Recreationally, Ahlgren has been a licensed private pilot, an avid sailor, and a not-so-avid skier.
