I’m a fan of Catherine Ryan Howard, whose books are always suspenseful and never predictable. The Trap, based on a series of real true crime cases, was no exception. Check out my Review of The Trap by Catherine Ryan Howard, which I have deemed the Creepiest Mystery I Read in 2023 AND put on my list of Travel Thrillers Set on Airplanes Boats Trains and Cars!

Plot Summary for The Trap by Catherine Ryan Howard
One year ago, Lucy’s sister, Nicki, left to meet friends at a pub in Dublin and never came home. Nicki is the third Irish woman to vanish inexplicably in as many years, and the agony of not knowing what happened that night has turned Lucy’s life into a waking nightmare. So, she’s going to take matters into her own hands.
Angela works as a civilian paper-pusher in the Missing Persons Unit, but wants nothing more than to be a fully-fledged member of An Garda Síochána, the Irish police force. With the official investigation into the missing women stalled, she begins pulling on a thread that could break the case wide open—and destroy her chances of ever joining the force.
A nameless man drives through the night, his latest victim in the back seat. He’s going to tell her everything, from the beginning. And soon, she’ll realize: what you don’t know can hurt you.
Review of The Trap by Catherine Ryan Howard

I’m a fan of Catherine Ryan Howard’s books. I’ve read 56 Days and Run Time.
Both those books (56 Days especially) featured an interesting narrative structure, family relationships, and a lot of surprises.
The Trap was, according to the author, inspired by the Vanishing Triangle murders of the 1990s, a still-unsolved series of disappearances and murders in and around Dublin from the late 1980s to the late 1990s.
Ryan uses these real-life cases to point out that decades ago, there was a great deal of institutionalized sexism and religious-based slut-shaming in the police department, something that prevented these cases from being solved. Now they have gone cold and someone got away with it!
Another mystery writer has written a non-fiction book about these cases. I thought it was fascinating and I definitely recommend reading that as well!

In The Trap, Lucy is distraught over her missing sister Nicki, who Lucy is certain must have been taken by a local serial kidnapper of women. When Lucy becomes convinced that the task force investigating the cases isn’t doing their job, she starts poking around on her own.
Denise, a missing persons investigator for the Garda, the Irish police, is the Family Liaison Officer assigned to Nicki’s case, is trying to balance office politics with finding the missing women.
Angela, is a civilian employee of the Garda, dreams of becoming an officer herself. One day, she takes a phone call at work from a woman who claims to have important evidence in a missing persons case.
Then, finally, we have the chilling POV of a man who has forced a young woman into his car and wants to tell her a story…
The Trap was a very twisty read, and I enjoyed all the strong female characters, from Lucy to Angela to Denise.
The ending of The Trap was definitely unexpected. First, the ending makes you realize that a lot of things you assumed are wrong.
Based on the comments, most of us were only partially successful in understanding everything the first time around.
I have read other books with a similar technique but I definitely didn’t see these twists coming. At all.
If you enjoy true crime-inspired books and love a book that can take you by surprise, try out The Trap!
UPDATE: I hadn’t planned to do a Spoiler Post for The Trap and just read it for fun. But clearly there is a LOT to talk about in this book.
I know that most mystery readers hate and avoid spoilers but honestly (!) this is a book that makes more sense if you do know the end. I ended up reading it twice and the second time everything made sense.
I will ask going forward that all spoiler discussion happen on the Spoiler Post here for those readers who want to be surprised or try to figure things out themselves.

The comments below this post DO contain spoilers, so proceed with caution.
Please don’t leave new spoiler comments here, come over and discuss the twists. I figured out a few new things!
I felt this one was much darker than her previous books…not sure if I liked that.
I agree. It was VERY dark!
I have no idea what happened at the end!! Would you be able to tell me…if there was a twist, I didn’t get it😬
SPOILERS AHEAD BEWARE
Lucy is worried about not being able to find her sister Nicki and thinks that she got taken by a serial killer who has been abducting women. Lucy tries to get the police to take her seriously. The killer does have a woman he’s taken whom he speaks to in his POV chapters and whom we assume is Nicki.
However, Nicki is just irresponsible and was just went off and didn’t tell her sister.
Lucy, in her investigation of her sister’s disappearance, makes a TV appeal to the abductor and says: come and get me. I will go with you. And he does! So Lucy is the one in his car, not Nicki.
And of course, Nicki will not do the same and try to find her.I deleted that sentence because I think David (below) was right. Nicki DOES try to find her sister and even ends up briefly in the guy’s car but then I think its suggested that Denise spots the guy at Circle K and is suspicious of him? And hopefully finds Lucy too?
This story is so dark and the sister switch twist really got me! I can’t say I liked the ending but it did really surprise me.
SPOILERS BELOW. DO NOT READ IF YOU HAVE NOT READ THE BOOK.
Now I’m even more confused. You write “Nicki will not do the same and try to find her,” yet it’s revealed that it was Nicki not Lucy who is acting as bait in the titular trap we see at the beginning of the novel (and we’re seeing the same scene fleshed out more at the end, unless we believe both sisters had an almost identical experience there). So she is indeed putting herself at risk to find her sister.
The part I didn’t understand was that the killer (we assume) lets her go at the Circle K, and when Denise, the cop, sees her emerge from the bathroom, she’s crying. Why? Did the killer tell her what he did to Lucy? But if so, why did he let her go? It seems people are confused by the ending in different ways! I like your review, by the way, but I’m still not sure I’ve fully grasped the ending, and I’m scouring the internet to see if there’s a definitive interpretation.
THIS COMMENT HAS SPOILERS FOR THE ENDING
David I am so glad you left this comment because I went back and looked and you are right.
It IS confusing. And I am the worst with character names, which is one of the reasons I started taking notes which turned into my Spoiler Posts.
I got the sisters’ names switched. So Nicki went off with the boyfriend, then Lucy uses herself as bait to try to catch the guy who she thinks took her sister and gets kidnapped. Then Nicki emerges and and tries to do the same thing (weird!). But doesn’t Denise shows up at the Circle K and gets her “feeling” and hopefully arrests him and finds Lucy?!?!?
Let me know if you have further thoughts!!
It really is confusing! I liked the novel a lot, but I was slightly disappointed, not so much that the ending was ambiguous (I have a high tolerance for ambiguity) but more because I didn’t feel I fully grasped it. I always have to remember that the problem could be me, though! 🙂
But I loved 56 Days by the same author so much that I did feel slightly disappointed by this. And since I commented here, I kept searching and found almost nothing in terms of an explanation for the ending. I did find this answer on Goodreads, which addresses some of the questions we’re asking (but again, it’s only one person’s interpretation):
How odd that they used the same phrase, “fleshed out,” but it does feel a little closer to how I thought it ended. In other words, if the same guy (he does appear to be the same) who stopped for one sister at the beginning also stopped for the other sister at the end of the novel, that would be too much of a coincidence, I think. So if they’re actually the same event, we’re just given more details the second time around (that Denise was observing, for example, and therefore there is hope he might be apprehended), and I think we’re meant to think Nicki is so racked with guilt now Lucy has been taken that she is putting herself in danger to try and save her (trying to atone for her earlier indifference and irresponsible behaviours). We’d just all assumed it was Lucy at the start as that made sense initially, without all the other details.
But yes, I’m speculating a little here, but it’s driving me nuts, lol. And absolutely, if you find any more answers, please let us know. 🙂
SPOILERS BELOW. DO NOT READ IF YOU HAVE NOT READ THE BOOK.
I feel like I need to read it again and maybe I’ll get it. I had originally decided to just do a quick read on this with no Spoiler Post but I think that was a mistake.
The one thing about the correct interpretation that makes less sense to me than my original (wrong) interpretation is that Lucy IS looking for her sister, whom she thinks was kidnapped but the police won’t take her seriously. She makes an appeal on TV that she will go with the guy and then … he actually comes and takes her? Surely the police are looking for her at that point?
And then Nicki returns and feels guilty and then tries to go and get kidnapped? And then the guy takes her and lets her go?
Now that I write this out it’s rather bizarre to me.
SPOILERS AHEAD. DO NOT PROCEED UNLESS YOURE DONE.

So the end of this one is confusing AF but I think I thinkkk I figured out the whole twist here.
So the first scene we assume is Lucy searching for Nicki, but find out later it is actually Nicki searching for Lucy.
Bad guy (Darren Turner)says “Lucy OSullivan had come willingly, but shouldn’t have. There were no others, and he’s stopped now. Stopped taking them and stopped visiting the Pink House. But that doesn’t mean he can’t have a little fun.” So ifso facto, Lucy is probably dead, and he had no interest in taking Nicki, just making her sweat because he knew who she is, etc. Gives that whole first scene an eerie dark turn.
The whole time he is taking through the book, he is talking to Lucy when we assume it is Nicki or his latest victim.
Lucy in the beginning talks about her “late night excursions” and how they’d make Chris upset again, which we assume is wandering around in high heels turning to find the guy who took her sister, but we find out in the chapter “The Trap” that her late night excursions weren’t that, but watching Roland Kearns home.
So the whole twist is the beginning is Nicki and the bad guy is taking to Lucy the whole time and Lucy is presumably dead now by some dude named Darren Turner. Which is annoying because who TF is Darren Turner.
SPOILERS BELOW
Ahhhh… thanks for that. I decided to re-read and am not yet to the part about Lucy watching Roland.
Since this book is diabolically confusing I am going to do a full spoiler post so people who just want a review don’t have to avoid all the comments!!!
I thought this book was really good and loved the twist, I didn’t find it confusing at all!? Hopefully there’s a sequel 🤞
lol you must be a very careful reader. There were actually two twists, discussed on my Spoiler Post. Maybe you got them both!
