Look, I need to get something off my chest before we go any further: if you're going to build a thriller around a Christmas Eve disappearance involving a Swedish holiday tradition, you better make me forget I'm sitting in my truck at 11 PM outside a client's warehouse in Cedar Park waiting for their overnight security rotation to show up. And for about the first two hours, Duffy actually pulled that off.
Let me cut to the chase - Stranger Book 2 is a decent mystery that doesn't quite trust itself enough to be great.
The Setup Is Sharper Than a K-Bar
The premise hooked me immediately. Fergus heads out on Christmas Eve to do the whole Swedish "Pappa goes to buy a newspaper and comes back as Santa" bit for his kid Alfie - and just vanishes into the snow. Then you find out he's not the only father who disappeared that night. Bodies start turning up. That's a hell of an opening gambit, and I was locked in. The holiday setting works because it weaponizes something innocent - a family tradition - and twists it into something genuinely unsettling. Alex's determination to find Fergus while simultaneously trying to hold things together for Alfie gave the early chapters real momentum.
But here's where it lost me - or at least where my attention started drifting. The middle act spins its wheels. Alex runs down leads that feel circular, and there are characters who show up, contribute nothing meaningful to the investigation, and disappear. I've sat through enough after-action briefings to know when someone's padding the timeline instead of tightening it. At under eight hours, this book shouldn't feel like it has filler, but it does.
The Alfie subplot - the kid knowing "the bad lady is watching them" without understanding what he's seeing - is genuinely creepy and probably the strongest thread in the whole book. Duffy understands that a child's half-comprehension of danger is more unsettling than any explicit threat. I just wish she'd leaned into it harder instead of parceling it out in tiny doses between stretches of Alex doing what amounts to investigative busywork.
Froggatt Gets the Job Done (Mostly)
Joanne Froggatt - you'll know her if you watched Downton Abbey - brings a solid, grounded quality to Alex. She reads with enough urgency during the tense sequences that I bumped my speed back down to 1x for a couple of chapters, which is about the highest compliment I give a narrator. Her emotional register when Alex is oscillating between controlled determination and barely-contained panic feels authentic.
Here's the but, though. The kid voices. Specifically Alfie. I've heard fellow listeners complain about this and they're not wrong - Froggatt pitches the child voice into this slightly whiny register that grated on me every time Alfie had extended dialogue. And since Alfie is carrying one of the most important subplots, you can't just tune it out. It's not a dealbreaker, but it's a consistent irritant, like a rock in your boot on a long ruck march. You notice it every single time.
The rest of her character work is competent without being remarkable. She handles the Scottish and Swedish name pronunciations without tripping, and her pacing during the body discovery scenes is appropriately measured - she doesn't rush the horror, which I appreciated.
The Whodunit Problem
I've seen people call the resolution predictable, and... yeah. I had my suspect pegged by the midpoint. Now, I'll grant that I read a lot of thrillers and my pattern recognition is probably more tuned than the average listener's, but the clues aren't exactly buried deep. Poet managed to genuinely blindside me at the same stage - that one earned its twist. The "bad lady" thread, which should've been the devastating reveal, lands with less impact than it deserves because the book telegraphs too much too early. Duffy can clearly write suspense - the Christmas Eve disappearance proves that - but she needs to trust her reader more and explain less.
That said, this is Book 2 in a series, and it carries the weight of continuing character arcs from the first installment. If you're already invested in Alex, the character development here might matter more to you than the mystery mechanics. I came in cold (hadn't listened to Book 1) and managed fine, but I suspect some of the emotional beats around Alex's relationships would've hit harder with context.
Who's This Mission For?
If you like domestic thrillers with a holiday setting and don't mind a slightly predictable payoff, this'll scratch the itch on a winter commute or a long evening drive. If you need your mysteries airtight with genuine surprise at the end, you might find yourself frustrated. Skip if child character voices in audiobooks are a hard no for you - Froggatt's Alfie will test your patience.
Cooper's Debrief
Worth your time? Conditionally. The premise punches above its weight, Froggatt is a capable narrator despite the kid voice issue, and at 7 hours 49 minutes it doesn't overstay its welcome (even if the middle sags). But the predictable resolution keeps this from being something I'd spend a credit on. Stream it on a subscription service, listen during your commute, and enjoy the Christmas Eve setup for what it is - a genuinely clever hook that deserved a tighter book around it.
Ranger fell asleep during the middle chapters. Make of that what you will.
