The Blue Hour by Paula Hawkins: Jen’s Quick Take

- A haunting psychological suspense story, The Blue Hour was one of my favorite reads of 2024
- The story features two third-person narrators, epistolary elements, and an intriguing setting and characters
- I think The Blue Hour is Hawkins’ strongest book yet.
- Will it please fans of The Girl on the Train? It’s a very different book. I found it darker and more complex, both structurally and thematically. This is not a people pleasing book with “relatable” people pleasing characters. It would be a GREAT book club pick.
- Some unhappy readers found it slow paced. Others complained that it was too focused on art and “snobby” art world characters.
- If you prefer a linear narrative and first person POV characters you can root for, this one probably won’t be for you.
- If you like dark, complex characters, a truly spooky setting, and an ending that will disturb you, this might be for you!

Plot Summary for The Blue Hour by Paula Hawkins
I waited too long to write this post after I finished the book, but wanted open up a discussion. If you think I left something important out, please tell me in comments!
Art expert James Becker is asked to look into a shocking accusation: that the late artist Vanessa Chapman incorporated a human bone into Division II, a piece she created in 2005. The fact that her philandering husband mysteriously vanished in 2002 before adds gossipy fuel to the art world chatter.
The Blue Hour is made up of two third-person narratives: James Becker’s narrative and another by Grace Haswell, a friend of Vanessa’s who is the executor of her estate. The book also incorporates diary entries from the late Vanessa Chapman.
Vanessa left her entire estate to the Fairburn Institute, a foundation run by her former gallerist (art dealer), Douglas Lennox. The Lennox family ask James to investigate the bone situation AND get Grace to hurry up and finish her executor duties.
Grace has been dragging her feet on sorting Vanessa’s artwork and papers in her role as executor. She is also extremely hostile to the Lennox family.
James Heads to Eris Island
Eris Island is practically a character in the book. It’s a tidal island in Scotland, a spit of land that becomes inaccessible when the tide in the Irish Sea is high.
Where is the Irish Sea, you ask?

So (I think) Eris Island has to be located on the Southwestern coast of Scotland.
The book mentions Glasgow, and that James is from “down in the Borders,” which means the part of Scotland close to England, so I’m guessing the book is set in the area south of Glasgow.
Who is “The Wicked Witch of Eris Island,” Grace Haswell?

- James Becker visits Eris Island talk to Grace, who is an interesting character. She’s a doctor and extremely prickly.
- Vanessa has been dead for five years, but Grace has still not sorted out all Vanessa personal letters and papers (to fulfill her role as executor).
- The Fairburn Institute claims there are missing paintings.
- James wants to know if Vanessa mentions the mystery bone in her journals.
- An offended Grace kicks James out.

What did you think of The Blue Hour? Please tell me in comments!
Did Grace poison nick? I thought she strangled him.
Did Vanessa know that Grace murdered Nick? It seems like she used his bone in her piece as a way to let Grace know that she knew more than she was letting on about Grace’s true character. It did not seem like a random coincidence but there is no mention of Vanessa finding the bone. I still have so many questions about the ending.
No, you are right! I wrote Nick instead of James in my notes. Thanks so much for pointing that out and I will fix it.
As for whether Vanessa knew, I am not sure. But I really like your theory about her doing it to mess with Grace. I mean, she did paint the strangulation scene, but I guess she was there.
And didn’t Grace say that Marguerite knew or suspected that Grace killed Nick?
I didn’t care for the end, I’m assuming Becker died?
I think so. I sort of saw it coming and I hated it too, but it fit. I guess we can just pretend that someone saved him??
But weren’t the blue lights the emergency services at the end?
I love this interpretation of the ending!!
I didn’t realize Scottish ambulances had blue lights. Where I love in the US they are blue and red (police) or red and white (fire and ambulance).
But even if Sebastian thought something was wrong, I’m not sure he would have realized (as Becker did) that Grace killed Nick and that Becker was in terrible danger. Or if emergency services would get there in time as Becker is nearly underwater.
Plus the book makes a LOT of the fact how dangerous it is to try to drive across at high tide. It’s nicely set up.
My interpretation is that Grace (reluctantly) kills Becker so he won’t expose her as a murderer. Sebastian gets Helena.
But I hope more people read the book and weigh in on their interpretation. I could be wrong. It’s far from clear!!
Aren’t the blue lights the police?
Fiona, I have edited the ending explained because Kathryn also thought he was saved (or at least that someone was coming to save him.)
Are you from the UK? Where I live in the US, a police car has red and blue lights, and a fire/ambulance red and white. I now realize that in Scotland, where the book is set, the rescue vehicles have blue lights.
I still think that James died at the end of The Blue Hour.
a) they are on a small, isolated spit of land, far from help. He can’t use his phone.
b) based on the title of the book, blue is thematic. I am reading a paper copy so I can’t search as easily but I’m going to go back and look
c) as much as I kind of hated the ending, it fits. Grace outwits everyone in the end.
But I could be wrong. I agree with you that it is far from definitive!! I love books like this where we can debate things ๐
This is not my kind of book. I truly dislike ambiguous endings!
I usually agree and am EXTREMELY annoyed when an ending is ambiguous. But:
a) I’m not sure if this ending was intentionally ambiguous. There have been several books recently, like this one or this one where the author thought the ending was perfectly clear. But readers disagreed. In fact in that last example people had multiple endings figured out that were plausible and well-supported in the text.
b) my interpretation of the ending of The Blue Hour, while dark, seems to fit the story and is a great homage to Daphne DuMaurier. So I am okay with it. But fully support the theories of others who want to have a more positive take ๐
I think that you are right. (I’m also not fond of a dark ending either. Lol! Sometimes I don’t mind but maybe I was already too unhappy with this book.)
I love your website! As soon as I finish a book, I come here to see if you’ve read it too. Also, months later, it really helps me when I can’t remember what a book was about. Thank you!
Thanks so much for the kind words! And I am clearly the outlier on this book as the Goodreads rating keeps dropping!
Loved it
Yay. Glad you agree.
I felt the ending was intentionally ambiguous. I thought it made more sense that he was dying, but I thought the random blue lights were the emergency services. I am going with the latter as I prefer to be optimistic at the start of the year,
You are not alone, Deb! In other books I have decided to go with the optimism too ๐
