My Readers Guide for Nobody’s Fool by Harlan Coben has character lists, plot summary, spoilers and the ending explained. I’m here to help you sort out some tomfoolery: Fool Me Once, a 2016 Coben book, was adapted for Netflix in 2024 with some changes. Then Coben wrote Nobody’s Fool, a 2025 spin-off to Fool Me Once which incorporated those changes. It’s classic Coben mayhem and I’m here to help you figure it all out!

Jen’s Quick Take on Nobody’s Fool:

What is the deal with Nobody’s Fool? Is it a sequel and to what?
Here’s my most succinct explanation:
- Nobody’s Fool follows a minor character (an NYPD detective) from the 2016 book version of Fool Me Once who was renamed and made a major character in the 2024 Netflix series. Still with me?
- So I’d call Nobody’s Fool a spin-off of the Netflix series which is an adaptation of the book.
- Nobody’s Fool is a PI Procedural with a morally gray main character and some very clever twists and turns.
- It also has a couple of inconsistencies (one timeline, one character background). I will check the finished copy before mentioning them here.
- Thanks so much to Grand Central Publishing for the advance copy. I really do enjoy Coben’s punny humor, chaotic mind, and out-there plot lines.
- Publication date: March 11, 2025

Do you need to read and/or watch Fool Me Once before reading Nobody’s Fool?

Every reader has their own rules about reading sequels without reading the original book.
But this is a weird situation: Nobody’s Fool is not exactly a sequel to either the book or the series. It combines elements of both the Netflix show and the 2016 book.
I think it’s up to you. While reading or watching Fool Me Once does provide important backstory, it also makes reading Nobody’s Fool a little more confusing.

You can also read my full plot summary of Fool Me Once!
- Sami Kierce was called Roger in the book
- He was one of the NYPD detectives investigating the death of a guy named Joe Burkett
- The Burketts run a huge pharmaceutical company (think the Sacklers from Painkiller on Netflix) and some of them are pretty shady
- Two Burketts factor in Nobody’s Fool: Judith Burkett is the family matriarch and Caroline is her daughter
- The Netflix show gave Kierce a new fiancee (now wife) named Molly and a partner named Marty McGreggor

You can also read my series summary of Fool Me Once
- Sami Kierce is no longer British! He has morphed back into an NYPD detective, as he was in the book Nobody’s Fool.
- Sami and Molly had their baby, named Henry
- Sami’s prior Britishness and prior health problems (remember that he was poisoned by a Burkett drug) are not mentioned.
- But Sami has been suspended from the NYPD and is now freelancing as an investigator for a law firm.
- Nicole was a character in the show (Sami’s AA sponsor) and now Sami has an ex-girlfriend named Nicole, an NYPD detective and murder victim. I don’t think they are supposed to be the same person, but … maybe? Why give them the same name. Paging Harlan!!

Whoa! That was quite a ride! What do you think about this book and the ending? I guess we will get another Sami Kierce book?
I haven’t read anything by Coben yet. Or watched any of the Netflix shows – but the books always come highly recommended so maybe one day lol
There are SO many books. He has standalones and multiple series. I really liked this one, but it is a spin-off/sequel so you might not want to start with it!
Who is Maya ? . Is she a Burkett and why does Judith ask if Kierce has seen her grandaughter , Lilly ? Does it have to do with Fool me once I loved this book Nobody’s Fool
First off, I agree with you! I think Nobody’s Fool is one of Coben’s best.
Yes, these are Fool Me Once characters. Maya was married to Judith’s son, Joe Burkett, and Lily is Maya and Joe’s daughter. Kierce investigated Joe’s death and got to know Lily and Maya.
