The AP’s Hillel Italie reports that Scott Turow‘s next project is a sequel to his bestselling debut thriller PRESUMED INNOCENT. Turow, speaking to AP on Saturday at BookExpo America, said he has written about one-quarter of a novel featuring the famed chief deputy prosecutor who investigated, and was eventually accused of, the murder of his colleague and former mistress, Carolyn Polhemus. “I got the idea a couple of years ago when I was working on a serialized book for The New York Times,” explained Turow. “I had this image of a man sitting on a bed, near the body of a dead woman. And then I realized, ‘Wait a minute, that guy on the bed is Rusty Sabich!’ And that’s how I began the new book.” The new novel, currently untitled, would probably not come out before the summer of 2009.
