Mystery Sub-genres - Which Comes First

Writers have to know the genre or sub-genre of their story. Whether traditionally published and bookstore bound, or self-published e-book, sooner or later, someone is going to ask, “What kind of book is it?” And that’s genre.

Most genres today have a lengthy set of sub-genres. Today I’m going to focus on mysteries. I looked at lists of mystery sub-genres from a half-dozen sources and came up with over thirty. The ones that appeared on most or all of the lists included:

• Cozy and its cousin, the Amateur Detective
• Classic Whodunit
• Heists and Capers
• Historical
• Medical and Legal (Courtroom)
• Police Procedural
• Private Eye, including the darker side Noir
• Romantic
• Suspense and Thrillers, including Techno-thrillers
• Spies and Espionage

And most included mention of mixed genres, such as Mystery mixed with Sci Fi, Paranormal, Urban Fantasy, etc.

Suspense and Thriller are also considered genres in their own right with many of the same sub-genres as given for mysteries. The same is true for Crime Fiction.

Lists and definitions for oodles of sub-genres are easy to find. Take any mystery/suspense story and it will probably fall under one or more of those listed above. It’s the “more” that can cause a problem. What I did not find in my search of sub-genres was a hierarchy. Which sub-genre takes precedence of another?

Is a story about a private eye and a CIA agent who solve a murder while falling in love a Private Eye/Spy/Whodunit/Romantic Mystery? What about a spine-tingling thriller with a cop as the main character – Thriller or Police Procedural?

Obviously, some stories are easy to define. Others not so much. What do you think?

For writers - Is there a written or unwritten hierarchy for defining genres/sub-genres? Should there be?
For readers, how defined do you want the genre of a book to be before you buy?

Groaner of the Day:  (Just a short one today.)  The butcher backed into the meat grinder and got a little behind in his work.

Sub-genres - Now There's a Mystery

Like a lot of writers, I belong to several writing groups that maintain e-mail lists for exchanging information, questions, support, etc.  I have one that falls under the parent organization Sisters in Crime (mystery writers) and one whose mama-ship is Romance Writers of America - because sometimes it's a thin line between a "mystery with a strong romantic element" and a "romantic suspense".

The other day, a member of the mystery group posed a question about mystery sub-genres, asking for a list and some definitions.  Oddly enough, there wasn't the usual stream of responses.  In fact, there weren't any.  That struck my as odd.  In Romance, things seem clearer.  Pretty much every other chapter of RWA holds an annual writing contest and they all use the same sub categories:

Contemporary

Historical

Romantic Suspense

Paranormal/TimeTravel/Fantasy

Young Adult

Single Title

 

So what about mysteries?  I did a little online digging and came up with these (all were on at least three of the many lists I found):

 

Amateur Detective

Classic Whodunit
Comic (Bumbling Detective)

Cozy  

Courtroom Drama

Dark Thriller

Espionage

Forensic

Hard-boiled (noir)

Heists and Capers

Historical

Inverted (howdunit)

Locked Room

Medical

Paranormal/Supernatural

Police Procedural

Private Detective

Psychological Suspense

Romantic

Serials

Technothriller

Thriller

Woman/Child in Jeopardy

Wow.  That's quite a list.  And I imagine a lot of mysteries have elements of more than one category, right?  So what difference does it make?  Well, the problem comes when the author is trying to describe a book to an agent or an agent to a publisher or a publisher to a bookseller or a bookseller to a buyer.  They all have to answer one question, "What is it?" 

And the answer is supposed to fit someplace on that lovely list.

Oh.  Well, it's a Paranormal Private Detective Thriller with a Romantic Woman in Jeopardy.  Sort of.  I guess.

Think about some of your favorite mysteries.  Where would they fit on the list?  Would they fit somewhere on that list?  I'll bet you have some that do and others that need a description like the one in the paragraph above.  Can you share an example of a multi-sub-genre mystery you've enjoyed?

As a writer, do you try to write to a sub-genre/category?  As a reader, do you choose books based on that sort of label?

Note:  Follow up to my Monday post - as I write this, we're in the middle of another torrential downpour.  Still on target to break the record for the wettest April ever.

I'm currently enjoying: Murder on the Mind by L.L. Bartlett  (I could have finished this last night but my grandson started playing with my Nook, got caught up in the story, and wouldn't give it back to me.)

Groaner of the Day: A linguistics professor was lecturing to his class one day. "In English," he said, "a double negative forms a positive. In some languages though, such as Russian, a double negative is still a negative. However," he pointed out, "there is no language wherein a double positive can form a negative."

A voice from the back of the room piped up "Yeah, right."
