COZY MYSTERY FICTION STACK

Come on in. There’s a mystery to solve.

Build the sleuth, the town and the fair-play puzzle, with Auntie Alibi beside you in the course.

Genre guidanceAI writing workflowSeries planning

HI, I’M KATE RILEY

The books are cozy.
The planning can be, too.

A good cozy gives you 2 things at once. A mystery you want to solve and a place you don’t particularly want to leave.

You care who did it. But you also want another afternoon in the bakery, another conversation with the grumpy neighbor and another excuse to visit the sleuth’s slightly chaotic life.

I’ve been publishing fiction since 2011, across multiple pen names, with books on the New York Times and USA Today bestseller lists. I know how much thinking goes into a story readers enjoy without ever seeing the work behind it.

This course puts that work into steps you can follow with Claude or ChatGPT. You make the creative decisions. Your AI helps with the research, planning, drafting and checks. I show you what to look for before you keep the result.

You don’t need a ready-made town, a brilliant murder idea or years of writing experience. We build those foundations together.

THE COZY PROMISE

Give readers the mystery
and the comfort they came for.

Cozy readers have expectations. Your sleuth is an amateur with a believable reason to investigate. The mystery plays fair. The tone stays warm, even when someone in town has been up to no good.

You’ll learn those expectations before you choose your concept. Then they become part of your writing rules, so you and your AI have something specific to check the story against.

That makes the creative decisions easier. You’re choosing the kind of cozy you want to write while keeping the reader promise clear.

Warmth without the gore

An ending that feels right

Bring the mystery to justice and leave readers with a sense of community.

THINK BEYOND YOUR FIRST BOOK

Build a place readers miss.
Then give them a reason to return.

There’s a lovely opportunity in a series: readers get to know your people. When the next book arrives, they already have a reason to care.

You don’t have to invent a new town and a completely new cast every time. You keep the parts readers came to love, then bring in a fresh mystery, a different town event and new developments in the relationships.

That’s why we plan your series before drafting Book 1. Your recurring cast, longer story threads and series bible give the next book somewhere to begin.

A series gives your books more chances to find a reader and gives that reader more of a world they enjoy. The course helps you build the books behind that opportunity, without promising a particular income.

Plan the answer first

Work out the culprit, motive and evidence before drafting. Then place the clues and red herrings where readers can find them.

Build your author voice

Create your own voice skill and writing rules. Review the draft for clichés, repeated phrases and wording that doesn’t fit.

You’ll follow a sample series through the lessons so you can see the choices in context. Its sleuth, Del Corliss, is a retired music teacher who inherits a piano-tuning business in the lake town of Pell Harbor. Her perfect pitch makes her notice things other people miss.

Your sleuth and your town will be your own. The example shows you what to look for, so you have something better than a blank page to start from.

COZY MYSTERY WRITER IS INCLUDED

Use the prompts.
Or let the plugin guide the work.

Learn the decisions as you go

Paste the complete prompts, read what your AI produces, ask for fixes and save the version you approve.

Let Cozy Mystery Writer run the steps

The included course plugin asks questions, runs the step and saves files, while you steer the story and review the result.

Start with Manual Mode when you first meet a step, then use Shortcut Mode when you’re ready. You can mix both throughout the course.

Cozy Mystery Writer comes in versions for Claude and ChatGPT, with installation guidance. Its workflow reads the cozy promise, so genre rules travel with the writing process. It also includes a voice interview and a clue checker.

The plugin keeps your project files together and gives you a way to see where you are and what comes next. You stay in charge of the ideas, the choices and the finished book.

You get worksheets for choosing your cozy lane, building the recipe and comparing story concepts. Then there are cast cards, a series-plan variety sheet, a murder-plan template and a clue map to help the story fit together.

When you’re drafting, use the chapter review checklist and quick fixes. When you’re editing, use the story and fair-play audit, then the phrase-cleanup sheet.

And when the book is ready for its next step, the blurb, book matter, keywords and cover-brief resources help you prepare what readers see.

You’ll find PDF versions and editable Google Doc copies in the course resources. You’re adapting useful starting points to your own book instead of trying to remember every detail.

After Book 1, you update the series bible and plan the next mystery. The people and places stay recognizable while the murder, suspects and town event change.

Your voice rules and review process come with you, too. You’re building a way to work that you can return to for the next book and the one after that.

You still read, choose and approve the work. Having the foundation in place makes the next set of decisions easier to approach.

A FEW THINGS YOU MAY BE WONDERING

Let’s clear these up.

Do I need a book idea before I start?

No. The research and concept lessons help you choose your cozy lane, build a recipe and compare ideas before you commit.

What if I’ve never written a mystery?

We begin with the cozy reader promise, then build the sleuth, series and murder plan before drafting. You’ll use prompts and checks rather than trying to invent the whole process yourself.

Can I use Claude or ChatGPT?

Both. Choose one to start. The course includes the Cozy Mystery Writer versions and setup guidance for each.

Is the plugin part of the course?

Yes. Cozy Mystery Writer is the course plugin, with a guided workflow, voice interview and clue checker. You can also use the manual prompts.

How do I keep the clues straight?

The plotting lessons build a murder plan, clue map and chapter outline. The story edit includes a fair-play audit, so you have a way to check what readers can actually solve.

Will I have to write a long book?

You choose your target length. The setup and market research help you decide what fits your project. The process supports short reads and longer books.

Can I build a series with the same sleuth?

Yes. The course plans a recurring sleuth, cast and town, with a series bible and guidance for the books that follow.

Does the course include launch marketing?

The focus is creating your cozy fiction: research, planning, writing, editing and book packaging. Dedicated launch and marketing training is a separate offer.

What if I need help?

Ask Auntie Alibi inside the lesson. You can ask up to 10 questions a day, with a route to the support team after that.

How fast will I finish, and what will I earn?

That depends on the decisions, review and time you put into the work, and on how you publish and promote. The course provides guidance and tools; it doesn’t promise a completion date or income.

YOU DON’T HAVE TO START WITH A PERFECT IDEA

Your sleuth has a mystery to solve.
Let’s give them a book to do it in.

Auntie Alibi holding a mystery book, shown full length with both boots visible

Maybe you’ve pictured a little bookshop, a lakeside town or a sleuth who knows far too much about everyone’s business. Maybe you haven’t chosen any of it yet.

You can begin either way. We’ll research the readers, find your concept and build the pieces in an order that helps the story come together.

One book to start. A town to return to. A clear way to keep writing.
