Steve Cavanagh discussed his new book, Thirteen, on Thursday, August 22, at The Poisoned Pen in Scottsdale. The book is the fourth in the Eddie Flynn series. Flynn, a defense lawyer, believes his client is innocent, but he’s fighting an uphill battle against “a mountain of evidence and a ruthless prosecutor.” To complicate matters (not a spoiler, it’s on the book’s front cover) – “The serial killer isn’t on trial, he’s on the jury.”
