The Pie and Mash Detective Agency – J.D. Brinkworth’s Comedy Cozy

Last Updated on April 22, 2026

I went into The Pie and Mash Detective Agency wanting a light, cozy mystery with a bit of London flavor and a strong sense of place.

On the surface, it felt like a good fit for me. A missing person case, an amateur detective setup, and a title that leans into classic British comfort food all tick the right boxes.

This novel is written under a pen name, with J.D. Brinkworth being the shared name for Jo Dinkin and Catherine Brinkworth, a London-based writing pair clearly aiming for a playful take on the cozy mystery style.

After finishing it my feelings are mixed. I would not call this a bad book, and I can see why it has found fans. For me, though, it never quite worked.

The tone leans hard into comedy, and while that will be a plus for some readers, it made the mystery side feel thin at times.

I kept waiting to click with the characters, and that never really happened, which made the reading experience feel longer than it needed to be.

That aside, let me give you the rundown, and you can decide for yourself.

The Central Mystery and How It Unfolds

The story begins with Dev Hooper returning home to find his girlfriend, Nellie Thorne, missing. That setup is strong and immediately unsettling, even without graphic detail or high drama.

What adds interest is the idea that this is not the first woman with that name to vanish.

In fact, several women named Nellie Thorne have disappeared over the past fifty years, and the local police have never been able to link the cases in a way that leads anywhere useful.

This is where Jane Pie and Simon Mash enter the story. They are a millennial couple who sign up for a private detective night class without much thought, more as something to do than as a serious career move.

When Dev’s case is assigned to them as coursework, they find themselves dealing with something far bigger than they expected.

With limited notes, borrowed confidence, and a shared belief that enthusiasm can cover gaps in skill, they start pulling at threads the police left alone.

The idea behind the mystery is clever. The repeating name, the whispers among locals, and the sense that something old and unresolved sits beneath the surface all work well.

I liked the way the case tied present-day events to older ones, and I appreciated that the book did not rush straight to easy answers.

Structurally, the plot makes sense, and the final explanation does fit what comes before it.

That said, I struggled with the pacing. About two-thirds of the way through, I felt like the story was circling rather than moving forward.

The investigation became less engaging for me, and I ended up skipping ahead to the ending.

That is never something I like doing, but at that point, I wanted to see how it wrapped up more than I wanted to stay with every step along the way.

Jane Pie and Simon Mash

Jane Pye is the stronger of the two leads. She takes the work seriously, wants to improve, and clearly sees detective work as more than a passing hobby.

I liked her determination, and I could imagine her working well in a more grounded series where her skills grow over time.

Simon Mash, on the other hand, really tested my patience. I found him irritating rather than charming.

He often felt like someone drifting from one idea to the next, adding “private detective” to a long list of abandoned plans.

His casual attitude toward the case and toward life in general was meant to be funny, I think, but it wore thin for me. Instead of balancing Jane’s focus, he often undercut it.

What made this harder was the lack of backstory for both characters. We are told very little about where they came from or why they are the way they are.

In a shorter, punchier book, that might not matter. Here, it left me feeling disconnected. Without that grounding, their choices sometimes felt random rather than driven by personality or belief.

A Middling Review

This book is clearly aiming to be funny, and in places it succeeds. There are moments of sharp dialogue and scenes that play nicely with the idea of amateur sleuths taking on something well beyond their level.

If you enjoy cozy mysteries that lean more toward comedy than deduction, there is plenty here to enjoy.

For me, the humor often clashed with the missing person storyline. I found it hard to fully invest in the stakes when the tone kept stepping back into playful chaos.

That is a personal taste issue rather than a flaw, but it does shape how I felt overall.

I can see this book appealing to readers who like character-driven comedy and do not mind a loose, sometimes messy approach to solving crimes.

If you enjoy mysteries where the process is more about personality than procedure, this could be your thing.

In the end, The Pie and Mash Detective Agency was an okay cozy mystery that simply was not for me.

I respected the idea behind it and thought the central puzzle was smart. I just never connected with the characters, and Simon Mash in particular made the reading experience harder than it needed to be.

That said, I know this book has found an audience, and I understand why. It is light, playful, and clearly written with affection for the genre.

If you are looking for a cozy mystery that does not take itself too seriously and leans into humor over detail, it is worth a look.

Even though I checked out before the very end, I can still say this book knows what it wants to be.

This time around, I just was not the reader it was written for.
