Sure, we found out who killed Laura Palmer. But what happened to the rest of the characters on Twin Peaks?

We’ll get some of the answers when Showtime revives the cult classic in 2016, 25 years after the show’s original debut on ABC. But co-creators Mark Frost and David Lynch have said the show will pick up in present day, leaving lots of blanks to be filled in.

That’s why Frost is penning a novel to fill in fans on what’s happened since they left the small town in Washington State. Flatiron Books, a division of Macmillan, will publish The Secret Lives of Twin Peaks in late 2015.

Frost promises that readers will get an inside look at the mystery of who killed Laura Palmer, the central mystery of the original series, and a wrap-up of several story lines that were left incomplete when the show was abruptly canceled in 1991. “This has long been a dream project of mine that will bring a whole other aspect of the world of Twin Peaks to life, for old fans and new,” Frost said in a statement. “I couldn’t be more thrilled.”

But the real question is: did Big Ed’s flannel ever go out of style?
