Best-selling author Harlan Coben (The Stranger, Missing You, Stay Close) is launching his new novel, Nobody’s Fool, on Tuesday. What may surprise some fans is where the inspiration for it came from.

“This new book is actually about Adeel Akhtar’s character Sami Kierce in Fool Me Once one year after the events of that series,” Coben tells THR. “And what’s weird is that the Sami Kierce character, and his wife, weren’t major characters in the Fool Me Once book. So it’s almost more of a sequel to the TV series than the book. I don’t know any time that’s ever happened. Certainly, it hasn’t happened in my career.”

“Adeel’s character Sami was quite a small part in the book, so it was a big change we made for the series to really build that character out,” echoes series co-adapter and co-writer Danny Brocklehurst.
