A review by justinkhchen
One by One by Ruth Ware

3.0

3 stars

One by One is sharply written, and completely addictive; Ruth Ware took a risky gamble by re-framing the classic locked-room mystery of Agatha Christie, to tell a modern day thriller taking place during a company retreat among snowy mountain. It's risky because her intervention to the classic murder mystery formula might ultimately also be the book's downfall (see what I did there—for a novel involving an avalanche...), ending up not pleasing fans of either murder mystery or thriller genre.

The saving grace is the overall setup, and the cast. While not necessarily to everyone's taste, I personally find the corporate dispute and app development angle fascinating, as well as refreshing to read within this context. Ruth Ware does an excellent job weaving them throughout, without feeling like she is simply regurgitating her research on tech startups. The characters are well fleshed-out, believable as someone from that particular social circle (I've encountered a few in my life to confirm!). You end up feeling sympathetic towards (some of) them, which makes the lingering epilogue still enjoyable to read through.

My recommendation: go into this book without assuming where the story should go (based on an assumed genre standard), then you might extract more enjoyment out of it.

**Minor spoiler ahead**

Ultimately One by One is still a thriller at its core, just decked out in murder mystery ornaments. Even with the clues and setups, there's ultimately no real mystery to solve; the novel reveals the culprit quite informally at about 60% (I was dumbfounded, and thought this was simply a misdirect—so I guess in a way it did succeed as a 'plot twist'), which might dispirit readers who are eager to deduce and guess the murderer alongside. In hindsight, the fact One by One's narrative is written from such limited perspectives, should be a telltale sign that deception is never the game it's attempting to play.

On the other hand, the first half of the book might bore thriller seekers to death; like most locked-room mysteries, it primarily consists of: the group being dispersed → someone is killed with strange circumstance → the group assembles and goes over plausible motive and alibi → the cycle repeats, and Ruth Ware remains quite faithful to this rhythm. For readers who are expecting something more event-driven, similar to her previous works, might find the large cast and keeping track of everyone's whereabouts an exhausting chore.

One by One does have some narrative inconsistencies, which dampen the its overall plausibility. One being the blatant dismissal of character Kate, the chalet's booking manager. Being offsite from the avalanche, she has the knowledge and capability to send help immediately. But the novel simply ignores this in order to create an extended period of isolation at the chalet. The characterization of the culprit is another weak spot, who is extremely sharp and resourceful one moment, and completely dumb in others. his/her demise is led by a series of stupid choices, which is in stark contrast to the first half of the book, where he/she is able to murder multiple people without suspicion.

**Minor spoiler ends**

Ultimately, I had a good enough time with One by One, even though the trope-bending experiment is less than successful, and the overall pacing feels lopsided (I've rarely encountered an epilogue this excessive), the setting and the character still makes it an engrossing read.
