Writers tend to be solitary creatures. We toil alone for months on end, then, once a year, we emerge from our dens to publish a book. It can be a daunting experience, especially for someone like me, who is not gregarious and outgoing by nature. But there is one aspect of promotion I truly love: meeting my readers and answering their questions. During each stop on my book tour, I reserve the bulk of my time for a lively conversation with the audience. I learn much from these encounters-indeed, some of the comments are so insightful they take my breath away. There is one question I am asked each night without fail, and it remains my favorite: "How in the world did you ever think of Gabriel Allon?" The answer is complicated. In one sense, he was the result of a long, character-construction process. In another, he was a bolt from the blue. I'll try to explain.

In 1999, after publishing The Marching Season, the second book in the Michael Osbourne series, I decided it was time for a change. We were nearing the end of the Clinton administration, and the president was about to embark on a last-ditch effort to bring peace to the Middle East. I had the broad outlines of a story in mind: a retired Israeli assassin is summoned from retirement to track down a Palestinian terrorist bent on destroying the Oslo peace process. I thought long and hard before giving the Israeli a name. I wanted it to be biblical, like my own, and to be heavy with symbolism. I finally decided to name him after the archangel Gabriel. As for his family name, I chose something short and simple: Allon, which means "oak tree" in Hebrew. I liked the image it conveyed. Gabriel Allon: God's angel of vengeance, solid as an oak.

Gabriel's professional résumé-the operations he had carried out-came quickly. But what about his other side? What did he like to do in his spare time? What was his cover? I knew I wanted something distinct. Something memorable. Something that would, in many respects, be the dominant attribute of his character. I spent many frustrating days mulling over and rejecting possibilities. Then, while walking along one of Georgetown's famous redbrick sidewalks, my wife, Jamie, reminded me that we had a dinner date that evening at the home of David Bull, a man regarded as one of the finest art restorers in the world. I stopped dead in my tracks and raised my hands toward the heavens. Gabriel Allon was complete. He was going to be an art restorer, and a very good one at that.

Over my objections, the book was entitled The Kill Artist and it would go on to become a New York Times bestseller. It was not, however, supposed to be the first book in a long-running series. But once again, fate intervened. In 2000, after moving to G.P. Putnam & Sons, my new publishers asked me what I was working on. When I mumbled something about having whittled it down to two or three options, they offered their first piece of advice. They really didn't care what it was about, they just wanted one thing: Gabriel Allon.

I then spent the next several minutes listing all the reasons why Gabriel, now regarded as one of the most compelling and successful continuing characters in the mystery-thriller genre, should never appear in a second book. I had conceived him as a "one off" character, meaning he would be featured in one story and then ride -- From Amazon.com Amazon.com Review
