In the year 2000, Preston moved with his family to Florence, Italy, to write a murder mystery set in Tuscany. Instead of writing the novel, however, he became fascinated by the story of a serial killer named il Mostro di Firenze, the Monster of Florence. He teamed up with an Italian journalist, Mario Spezi, who was an expert on the case. In 2008 they published a nonfiction book, The Monster of Florence. The book won numerous journalism awards in both Italy and the United States. Preston has published a number of solo novels, including Tyrannosaur Canyon, Blasphemy, and Impact. Preston was Co-President of International Thriller Writers and serves on the Board of Governors of the Authors Guild. He is a Fellow of the Royal Geographical Society and a member of the Long Rider’s Guild. In 2011, Pomona College conferred on him the honorary degree of Doctor of Letters.
