Mandy Morton’s Hettie Bagshot Mysteries live in a world entirely populated by cats—no humans, just whiskers, waistcoats, and very British cups of tea. Before turning to crime (on the page), Morton worked as a musician and broadcaster, and you can feel the performer’s timing: jokes land with a little cymbal tap, and the cozy beats are tight. This first book sets up the formula: a new detective agency, a cheerfully odd best-friend duo, and a case that starts quaint and turns properly sinister. Think gentle Golden Age vibes, only everyone purrs.
What’s it about?
Hettie Bagshot is a tabby with bills due and a talent for asking questions no one wants to answer. She’s just launched the No. 2 Feline Detective Agency—named for her address, not her ranking—in a modest office above a shop that always smells faintly of shortbread. Rent is due, kettle’s on, and her first big decision is hiring: she brings in Tilly Jenkins, who is all soft cardigans and steel spine, the sort of partner who will label the biscuit tin and also pick a lock if the situation requires it.
Before the sign paint is dry, their first client arrives: a flustered administrator from an upscale care home for elderly cats, worried because “accidents” have begun to happen to the residents. At first it’s small things—misplaced spectacles, strange noises in the night—then a death that doesn’t add up, and then another “unfortunate incident” that feels less like chance and more like a pattern. The home (all polished floors, floral curtains, and a faint smell of tuna) is run by a formidable matron who insists everything is fine and whose smile says it very much isn’t.
Hettie and Tilly take the case and go undercover as casual staff. Cue a catalog of suspects: the iron-furred matron with a taste for order; a chef who takes pride in a fish pie that could conceal anything; a handyman who always seems to be in the corridor you need; a visiting choir with too much interest in the donation tin; and a scatter of residents with sharper memories than anyone assumes. Morton treats the home like a small village—cliques at the tea trolley, romances at the window seats, old grievances with long tails.
The first days are reconnaissance. Hettie charms her way into linen cupboards and record rooms; Tilly befriends residents who haven’t had a proper listener in years. A ledger doesn’t tally. A missing brooch turns up in a place it can’t have walked to. Someone has been fiddling with the night-door bolts. In the garden, the roses have been freshly disturbed. Hettie pockets a single odd clue (a distinctive button) and pretends it’s nothing. Tilly notes who always arrives a breath before trouble and who always arrives after with explanations. On their off-hours, the detectives repair to the corner café to compare notes over sardine toast and to argue, lovingly, about who should do the next risky bit.
The second act raises the stakes. Another resident dies in a way that could be called peaceful if you didn’t count the timing and the very deliberate way their personal effects have been rearranged. The home’s board wants everything kept quiet. The matron wants the detectives gone. Hettie’s instinct says stay; Tilly’s eyebrows say we’re staying. They split up to cover an evening event—music in the lounge, a raffle to raise funds—and Hettie spots a familiar face from an earlier, unrelated case lingering near the back office. Threads that looked separate begin to knot.
Weather moves in: a storm that knocks the lights, isolates the house, and turns cozy into claustrophobic. Morton has fun here, playing the classic country-house card. With the phones down and the doors bolted, Hettie and Tilly decide it’s time to flush the culprit. They stage a very polite trap, complete with tea and questions that seem harmless until they aren’t. Alibis wobble. A nervous staffer finally admits there have been “arrangements” about money and medicines. One resident—sweet as custard in the daylight—lets slip something tart and specific about grudges from decades ago.
When the reveal lands, it does so in layers rather than a single ta-da. The deaths aren’t random: they point back to a long-ago wrong involving wills, donations, and a cat who reinvented themselves after a disgrace. The person orchestrating the “accidents” isn’t the loudest suspect but the one who has positioned themselves as essential—a presence so constant everyone stopped seeing them. In the storm’s last crack, they make a run for it, using a servant’s corridor Hettie clocked on day one. Tilly, whose superpower is being underestimated, is the one waiting at the other end.
After the constables cart the culprit off, there’s tidy fallout. The home’s board is quietly reshuffled. Families get phone calls that mix apology with relief. A resident who’d been the butt of jokes turns out to have the sharpest memory and gets the thanks they deserve. Back on the High Street, Hettie settles the invoice with a discount (“old age shouldn’t be charged at full whack”) and Tilly reorganizes the files so the next case won’t require divination to retrieve a receipt. The agency has its first proper win, a reputation for discretion, and just enough in the tin to keep the lights on and the kettle filled. Also: a hint of romance for one detective and a hint of backstory for the other—threads meant to tug you into book two.
What This Chick Thinks
The full-feline world is more than a gimmick
It’s not just cat puns (though there are a few, and they’re cute). The social rules, the food, the holidays, the way “polite society” works—it all functions like a cozy British village that just happens to be whiskered. It adds charm without diluting the mystery.
Hettie and Tilly are a great odd-couple engine
Hettie barrels; Tilly calibrates. Their friendship feels lived-in and useful—banter when the plot needs air, competence when it needs teeth. I’m a sucker for sleuths who share snacks and secrets in equal measure.
A classic cozy structure that respects the stakes
Morton plays fair: red herrings, a contained suspect pool, clues you can spot if you’re paying attention. And while the tone stays warm, the victims matter. The elderly residents aren’t props; they’ve got histories that drive the crime.
Humor as seasoning, not spackle
Plenty of smiles—especially in the undercover sequences—but the jokes never paper over the darker bits. When the lights go out in the storm, the book lets you feel that shiver.
Worldbuilding breadcrumbs for a series
We get just enough of Hettie’s past, Tilly’s family, and the town’s gossip ecosystem to make the next installments feel like an invitation. If you like settling into a series’ rhythms, you’ll be happy here.
Heads-up for your taste
This is firmly cozy: low gore, low swear, high tea. If you want procedural grit or twist-for-twist’s-sake plotting, it’ll feel too gentle. And a couple of side characters lean archetype (formidable matron, oily handyman) before the final turn gives them depth.
Final Thoughts
The No. 2 Feline Detective Agency is exactly the comfort-mystery promise on the tin: witty, warm, and surprisingly sharp when the claws come out. It’s a purr of a series starter—light on its paws, clear-eyed about motive, and anchored by a duo I’d happily follow into any pantry, archive, or rain-lashed lane.
