Tess Gerritsen is the author of the Rizzoli & Isles books, and the second season of the television series based on her work begins tonight. Gerritsen, who practiced internal medicine as a physician for five years, now spends her time penning suspense novels that deal with medicine and forensic science. Gerritsen returned to her first love of writing while on maternity leave. She started with romance suspense novels, because she used to read romances during her medical residency. "I found that after a hard day working in life and death situations, that a romance novel was the perfect way to unwind," she said. Then Gerritsen got the idea for a book about the black market in organs and organ theft, and tried a medical thriller, "Harvest," which became a bestseller. "That was the first book that got me a really big audience, and I realized maybe I should be writing more thrillers. So, I’ve been doing it ever since." Gerritsen's latest book, "The Silent Girl," draws upon her own Asian-American heritage and brings Jane Rizzoli into Boston's Chinatown to work alongside Chinese-American Detective Johnny Tam. On the eve of the international book tour for "The Silent Girl," Gerritsen took a moment to sit down with Speakeasy. Read the interview after the jump.
