How cld you not love this book? Monster smut, Sherlock Holmes, Watson, a cute doggy, a dishonest sheriff and a very protective Bigfoot named Skookhum.
When Myra starts hearing strange animal noises and things happening on her farm, and the local police think she’s crazy and don’t take her serious, she calls in help from none other than Sherlock Holmes himself. Things aren’t as cut and dry as they seem and when Myra forms a relationship with skookum she will go to great lengths to keep him as safe as he does for her and her son.
This book is a spicy good time! Can’t wait to read the next book!

Dirty Sherlock pt. 2
came here for Victorian logic and pipe-smoking deductions and instead got SHERLOCK HOLMES DOING CRYPTID INVESTIGATIONS???
Excuse me???
Sherlock Holmes: The Cryptid Files – The Case of Bigfoot really said:“what if we take the most rational man alive and emotionally destabilize him with Bigfoot.”
And honestly? Mission accomplish

I had the pleasure to meet the author at an event yesterday and bought his book purely out of curiosity!! Once I picked it up I could not put it down! I must say this is my first time reading a paranormal erotica and I’d have to recommend it! Following Sherlock from London to Georgia and the journey was so cool to read! I also enjoyed the secret society’s connection from across the globe they really are every where! Very satisfying ending and hoping Myra and Skookum the best! Looking forward to reading the next book!

My friends, this was a vibes read if I ever saw one. I met the author at a local book fair. I had a great time talking to him and all the things in this story. I can tell he had an absolute blast writing it.
You won’t pick this up for the finely crafted prose. This was like one of those crazy B-roll monster or sci-fi movies that you enjoy because it makes you laugh so hard. It’s a spicy Sherlock Holmes fan fic that also blends monsters with Mexican and Native American folklore.
Yes, Myra does get it in with Bigfoot…a lot. Holmes gets his own encounter. However, there is no group scene (I had several ask me when I talked about it).
You will have to overlook a multitude of grammar and spelling errors and some figurative language that makes you scratch your head. But, if you want something that will make you laugh from the ever-unexpected events… you may want to check it out!

I absolutely love how this book has multiple stories in one just for it all to come together in the end. It’s a must read!!

Errors: ...Many. Leading me to round-down my star rating. :(
And seeing as this is a debut work, I'm going to put it under a spoiler wall just to condense it for the rest of the review.
Apart from a tragic misuse or lack thereof regarding commas and periods throughout, there is good, serviceable plot here to analyze! Each chapter flows succinctly; any divides of action are properly pinioned in the same chapter for context of identical or near-identical temporal flow. Each chapter was quick and snappy, and while that kept the story well-paced, an unfortunate side-effect is that the pace compressed the worldbuilding next to nil. For someone so acutely attuned to surroundings and cataloging sensory data, Sherlock rarely connects motive for those things. For example, the Dining Room Table of Many Adjectives™ sounds like a giant reused spool of baling wire that was sanded and whitewashed for use as a table, but despite its actual novelty to Sherlock as a rustic staple of waste-not, want-not backwoods culture, it's nothing but a thing to hold a bowl of soup to eat from. Not that me or any other readers require Thorngrave to establish how Sherlock pontificates over such a thing, but if we're placing an outlander in a foreign land, can we at least notice an obvious shift of class strata? Sherlock does it about a door on 94, so why not other times like this?
Now that I read that sentence, one would think me mad for having expectations for monster smut. Berate me as you like.
Nonetheless, there are many clever aspects about this book I enjoyed. The aphorisms were not only charming, but seemed class-appropriate. Watson's "straw into gold" (3) and "drink from the keg of glory" (4) establish a well-read education (access to European fairy tales) typically absent from Georgians in the postwar 1950s, so its fitting a Briton would utter these phrases. Myra's phrasing like "showed more complacency than a cat with a full belly on a long summer day" (42) and "sharp as a tack" (90) grounds Myra's characterization with simplistic, worldly concepts. Even the simile of "like a barrel of bourbon that swallowed dynamite" (54) is a nod to how prohibition contributed to how others relate sounds from this region. How she "continued to wiggle like a worm on a rusty hook" (133) is another effective simile, both describing Myra's struggle and Sheriff Spink's predatory actions during a situation in context.
What may surprise readers is the ending regards Sherlock's excusal of a serious crime... And it doesn't bother me. Agatha Christie's Poirot excuses M A N Y serious crimes when the motive outweighs the means of justice. "Murder on the Orient Express" and "Death on the Nile" are just two of likely many stories from the 1930's that bridged the very noir, late-Gilded Age, and early historical thriller Victorian eras, while passively pardoning serious crimes in the scope of an entire conflict. While I'm vaguely aware of Poirot's driving motives through cursory exposure, I can't provide astute awareness about Holmes outside of a cursory cultural awareness; the near-manic rivalry Moriarty bears for Holmes, whose obsession grates the patience with how borderline erotic Moriarty's fixation is with the man.
It's easy to compare similar crime thriller protagonists to Thorngrave's iteration of Sherlock Holmes set in the 1950's. Personal favorites "Richard Diamond", "Rocky Fortune", and "The Adventures of Sam Spade" all have male protagonists that carry themselves with a hard-nosed swagger and an appreciation for women with antagonizing curves because "bones are for dogs" (17). I established earlier that I'm overall unfamiliar with Sherlock Holmes' canonical characterization, so I can't speak in full confidence to the accuracy of conflating Holmes' attitude as comparable to the aforementioned radio-to-television drama mainstays. Nevertheless, Thorngrave creates an effective pastiche in the Holmes portrayal, apart from the opening chapter.
Watson says Sherlock's name, in conversation, e i g h t times (2 [x2], 3, 4 [x2], 5, 7, 8). Sherlock says Watson's name five times (3, 4, 7, 8 [x2]). In nine pages. Sure, use their names in narration to keep the dialogue clear a few times through... But not with each other. They know each other. They're the only two in the room. Why do they address each other by name? Are Sherlock and Watson's bodies being manipulated by bodysnatchers, only to be revealed in a later installment?Apologies if I just ruined a surprise twist.
While Thorngrave may have his homonyms in order while writing (a surprisingly difficult feat for even traditionally published writers), readers who may be more neurodivergent or distractable than me may have greater difficulty enjoying the work for its overarching intention. For a book that took me three hours tops to read and make notations, it should be no great burden to ply someone a bit more grammatically stringent to offer editing, either with a Chick-fil-A platter or from an English major on Kofi. There are likely those out there willing to do it for free; as proof, I just wrote this review solely "for the love of the game", as the kids would say. And it took me longer to write this review than to read the work.
This work is for those like me, who love the concept of the unknown among us and cryptozoology as a trope and construct that challenges the scientific acceptance of a standardized, natural order. I'm bemused and heartened by purveyors of this genre who sincerely embrace and accept humorously philosophical and (mostly) fictional irreverence. Those who have a hunger for strangeness and what others would deem a profane corruption of literary pornography are their own irony at the end of the day. It doesn't have to make sense to be entertaining... All I want is for it to be proofread by being read aloud. A tinge of post-war pulp art for brevity can be (and is) sold separately.
And to revisit one of my classic bits of criticism in adult fiction works...
...Why'd the only redhead have to be a witch? I mean, we are made of magic, but still! *bratty noises intensify*

This is a wacky book that mixes Sherlock Holmes, Bigfoot, and hardcore sex. A smut book for dudes! I would have loved more plot, but I think that’s kinda the vibe. Local author that was exceptionally nice and I’m glad I bought his book. Will read his other stuff.

OKAY ALOT TO UNPACK
I do have to say I did dnf. NOT BECAUSE I DIDNT LIKE IT- I did! I liked the writing style, the story and the plot! and after thinking about it, I'm blaming being hangry.
so! sherlock is travelling from the UK to the us after receiving a letter from a women who is having some trouble with a unknown beast haunting her in the woods out from of her house. while on the boat over he meets a waitress, and they start getting freaky, she gives him a....massage I'm going to say and OUT OF ALL THE LANGUAGE USED the author uses "English sex pole"
"sherlock felt the warm and moist flesh touch his mouth and he began shoving his tongue in and out of her softly. the inside of Selma grabbed his tongue as if a hundred tenacles grabbed hold" YUCK but then it became apparent that Selma wasn't human...
it appears that everyone sherlock meets on his travels is some sort of legend or mythical creature
" Vlad from Romania"
"la Llorona from Mexico"
"Aaron who knew a little too much about jack the ripper"
" the beast moved his leathery hands up her thighs and into her flower"
and that's where I stopped..
I was having a good time reading it, its funny and quirky. OF COURSE a monster romance about bigfoot is going to be funny, but the use of the words "English sex pole" and "flower" pushed me a little over the edge while being hangry, but I do think I'll come back to it.

Sherlock Holmes, The Cryptid Files: Case of Bigfoot was an unexpected and intriguing read. I was immediately excited going in because it combined two things I don’t often see together...Sherlock Holmes and spice. That alone made it stand out.
What worked for me was the choice to move away from the usual Holmes-versus-Moriarty framework. Instead, the story centers on a secret society that appears to protect paranormal creatures, including Bigfoot. This society takes the place of the traditional nemesis and gives the mystery a very different structure than classic Sherlock Holmes stories.
Bigfoot himself is introduced less as a mystery to be solved and more as a sexual presence for the FMC, which clearly sets the tone for how the cryptid element is used in the story. The book isn’t afraid to lean into this unconventional approach, blending mystery, paranormal themes, and erotic elements in a bold and niche way.
Overall, this is a distinct genre mashup that will appeal to readers looking for something outside the boundaries of traditional Sherlock Holmes interpretations,especially those curious about paranormal erotica with a familiar literary figure at its center.

Where to start? I went into this read slightly biased as I adore the author and his super kind and friendly demeanor, but but, Sherlock Holmes? Cryptids? A mysterious symbol that keeps showing up? What does it all mean? Add some spice (and everything nice) and you have this amazing read! From a sassy ship server, to a librarian???? What will happen? This was a delicious mix of romance, mystery, and suspense, a tall broodin furball with touch her and unalive vibes? I could go on, but I'll let you in on a little secret, read this book, and you'll be safe from Carmen!!! She's fiesty, and really good with a letter opener... don't know what I mean? read the case and solve it for yourself!
Amazing!
Amazing!

This is a fast paced book, that is a quick read. I enjoyed the twists and it is certainly not predictable. There are elements of witchcraft, suspense and smut. It might not be for everyone but if you enjoy an erotic suspense/ thriller type of book then give it a go. I am looking forward to the sequel.
September 24, 2025
This was very unexpected and a great read!! There were elements of romance, horror, thrillers and mystery…all in one book about Bigfoot! I loved it. It has spicy scenes that were great, but the plot was the main focus. Can’t recommend this book enough!
April 4, 2026
loved this. I will admit it wasn't as spicy as book 2 but it was still a very good read for me. the mystery solving mixed with spicy is always on point. I like how the author puts his own twist to his books. his story is easy to follow and he keeps it intriguing.

Yassssss!!!!!!!!!!!!
Omg! This book is so good! I enjoyed this book so much. I have to go straight into the next one.

Such a fun read
I loved this story. Sherlock seems to ruffle some feathers, but in the end you will see just what happens with MS. Bedford.

What can I say I love this author! This book is a nice twist on Sherlock Holmes. It is a really good plot with Sherlock and Watson investigating their cases and getting to the bottom of what’s happening and running across new theories and new groups of society.
This is spicy! There is smut and there is monsters I mean what can go wrong. 😈 This book is a good time in my opinion it is not romance it is its own category spicy mystery! 😂
If you want a short read that is just a good time this is the book for you! 💜
