Author and attorney Scott Turow burst onto the bestseller list more than two decades ago with courtroom thrillers like "Presumed Innocent" and "Burden of Proof." Since then, his popularity has remained steady as he has become more publicly involved with controversial societal issues like capital punishment.

Turow will be in the Valley for two events. On Sunday night, he will sign copies of his new novel "Identical" at the Poisoned Pen in Scottsdale. Then on Monday, he will be at Arizona State University's O’Connor College of Law in an event presented by Changing Hands Bookstore.

"Identical" features Turow’s take on the myth of twins Castor and Pollux. I asked Turow where his interest in twins came from.
