No shit, Sherlock!!

Or! The ultimate rebuttal-quel!!

Figured this out during multiple Google rabbit holes.

Okay, this is a bit of a Kevin Bacon jury-rig, but fuck it.

Okay, it's WAY a Keven Bacon jury-rig.

Bear with me though.

The Cthulhu Casebooks:

Sherlock Holmes and the Shadwell Shadows (2017)

Sherlock Holmes and the Miskatonic Monstrosities (2018)

Sherlock Holmes and the Sussex Sea-Devils (2019)

Sherlock Holmes and the Highgate Horrors (2023)

And!

Sherlock Holmes vs. Cthulhu: 

The Adventure of the Deadly Dimensions (2017)

The Adventure of the Neural Psychoses (2018)

The Adventure of the Innsmouth Mutations (2019)

Yep!! Two Sherlock vs Cthulhu series by different authors were coming out at about the same time!

That must have been confusing to keep up with.

So, you can go with either, or both, but that gets us Sherlock connected to Cthulhu-verse.

Have I bought these?

Nope!

Am I gonna buy and read these?

Nope!

I've got enough goddamned books.

I just wanna comment on the existence of these ones.

Ditto the following ones.

Sherlock Holmes and the Servants of Hell (2016)

Your eyes don't deceive you. That's the Hellraiser puzzle-box.

It's Sherlock vs Hellraiser.

For a Sherlock vs Hellraiser pastiche to exist, you have to get Clive Barker's permission.

This is canon.

So! Hellraiser was always considered "Lovecraftian" and now by Kevin Baconing Sherlock, it fits in.

The Seven-Per-Cent Solution (1974)

The Adventure of the Peculiar Protocols (2020)

And! This is how we get to the rebuttal-quel part!

There's a whole longer series of these Nick Meyer ones, but these two in particular had the juiciest six-degrees meat to them.

"Peculiar Protocols" has Sherlock debunking "The Protocols of the Elders of Zion".

The Bible-of-Jew-hate read by the likes of Hitler and Henry Ford.

So six-degrees "Peculiar" into the Sherlock-multiverse, you get a Sherlock who would thumb his nose at Lovecraft.

Now, jumping back to "Seven-Per-Cent".

"The-Seven-Per-Cent Solution" crosses Sherlock with Sigmund Freud.

Data (from Trek) played Sherlock on the holodeck, and counseled with Sigmund on the holodeck, and Nick Meyer wrote "Wrath of Khan" and "Undiscovered Country" and UC crossed with TNG in "Unification".

And TOS crosses with Lovecraft through Robert Bloch.

So, there you go.

An anti-bigotry Sherlock vs Cthulhu and Pinhead as a prequel to Trek.

Crazy, right?

Ah, what the heck, I toss this in too...

The Real Ghostbusters (1987)

Real Ghostbusters links to Cthulhu-verse, and meta-connects to Sherlock.

In RGB's "Elementary My Dear Winston" Sherlock and Watson aren't real, but so many people on Earth believe in them, it makes them manifest.

My head-canon is a Lovecraftian alien-God read them in everyone's mind, and materialized them like the planet-brain in "Solaris".

Anyhoodles, Sherlock is just about as Kevin Bacon-y as Cthulhu, so they were bound to crash into each other. 

I just logged this particular path down for ya.

You can really go down an endless rabbit hole if you're a Sherlock junkie.

They've got him meeting Dracula, Frankenstein, the time Traveler from "The Time Machine", the Martians from "War of the Worlds" you name it.

Anyway! That's that particular weird-fiction chunk of it.
