Content Warnings: murder, poisoning, references to death, period-typical sexism, mild peril
Summary: Brilliant botanist Saffron Everleigh has set sail on her first research expedition, but it’s disrupted by accusations of murder when one of her fellow scientists is murdered in this daring fifth installment.
Saffron Everleigh is newly engaged and full of optimism as she sets off on the adventure of a lifetime for any scientist: a research expedition. She sails to newly formed Turkey with her fiancé, Alexander Ashton, and a bevy of fellow researchers under the watchful and reformed eye of Dr. Henry. With only two other women on board, Saffron soon finds she is right back in the same infuriatingly misogynistic environment that marked the earliest days of her career. Only this time, Saffron is determined to show everyone, including Alexander, that she can handle the trials of an expedition.
And trials she has in spades. Before the expedition team has even arrived, Saffron has managed to find an enemy in historian Joseph Clark, who frequently torments the assistant that Saffron has taken under her wing, Martin Neill. But when Martin unexpectedly dies, Saffron is targeted as the main suspect.
Falling ruins, venomous snakes, and mysteriously blocked passages are the least of Saffron’s worries. With unexpected help from a familiar face, Alexander and Saffron have to work fast to prove not only that Saffron is innocent but that they both have nothing to do with a larger conspiracy at play among the expedition crew.

There’s a certain kind of book that feels like pulling on a wool cardigan when the weather turns. Kate Khavari’s third Saffron Everleigh mystery, A Botanist’s Guide To Tradition And Treachery, is exactly that kind of read. It’s the literary equivalent of a foggy London morning, a strong cup of tea, and a dead body you weren’t expecting. Cozy, but make it deadly.
For anyone picking this up cold, here’s the gist. Saffron Everleigh is a research assistant at University College London in the 1920s, back when a woman holding a job in academia was basically a scandal all on its own. She knows her plants. She knows her poisons. And she keeps stumbling into murders that nobody else seems equipped to solve. Khavari has built a little world here, and book three settles comfortably into it. We went in curious and came out mostly charmed, with a couple of caveats worth talking about. So let’s get into it.
The botany is the real main character, and honestly? We’re not mad about it
Here’s the thing about this series that sets it apart from every other historical whodunit on the shelf. Khavari clearly loves her subject matter. The plant science isn’t set dressing. It’s woven into how the mystery actually works, how clues get found, how the whole thing unravels. You get the sense the author did her homework and then some.
For those of you who love a mystery with actual texture, this is where the book shines brightest. The poisonous plants, the academic settings, the careful little details about Saffron’s work. It all adds up to something richer than your average cozy. You learn things. You feel smart. That’s a fun combination!
The atmosphere does a lot of heavy lifting
If you’re someone who reads for vibes, and let’s be real, a lot of us are, this book delivers. 1920s London is practically its own character. The university corridors, the social rules pressing down on Saffron at every turn, the constant low hum of “you don’t belong here” that she pushes against just by showing up to work. Khavari is good at pace. She’s good at mood.
There’s something genuinely satisfying about a mystery that knows where it lives. You can picture the rooms. You can feel the chill. That immersive quality is a big part of why the series has the loyal following it does.
The mystery itself? Solid, if a little gentle
Now for the caveats, because we promised you some thorns.
The actual whodunit is engaging and well-constructed, but it’s not the kind of pulse-pounding thriller that’ll keep you up until 3 a.m. flipping pages. It’s a slow simmer, not a rolling boil. For cozy mystery fans, that’s the whole appeal. For anyone craving sharper tension or a twistier puzzle, the pacing might feel a touch leisurely in the middle stretch.
And that’s fine! Not every mystery needs to be a rollercoaster. But it’s worth setting expectations. This is a curl-up-and-relax read, not a white-knuckle one. Know what you’re signing up for, and you’ll have a lovely time.
So, should you read it?
If you like your mysteries clever rather than chaotic, steeped in historical detail, and led by a heroine who’s quietly fighting her own battles alongside the murder of the week, then yes. A Botanist’s Guide To Tradition And Treachery is a comfortable, satisfying entry in a series that knows exactly what it is. It won’t reinvent the genre, and it isn’t trying to. It just wants to give you a smart, atmospheric afternoon, and at that, it succeeds.
A few thorns, sure. But a bouquet worth picking up all the same!
Cozy mystery comfort food with just enough thorns to keep things interesting.
