This story is a sequel to A Monstrous Meeting of the Fourth Kind
After picking up a really cute outfit for the maid you recently acquired you return home. Not only that, but you have been given an invitation by Mrs. Rich to their family's Nightmare Night Costume Party.
Upon arriving you discover that your maid, Irisa has a few more secrets, that she hasn't told you about. Will this secret ruin your relationship or bring you both closer?
Here is an attempt to create another multi-chapter story for the Monster Mares and You series.
Sure, Halloween was cancelled this year because of the pandemic, but that doesn't mean we can't have some holiday fun, now does it? 
The cover art was created by: marking.

Finally!
I’m just happy to see more of this!

10469736 I'm glad you both are excited. I'm excited too, nervous, but excited.
I've missed your stories. I'm so glad to see a new one just in time for Spook-tober. I certainly hope Irisa will be all right.
10470111
Of course I’m excited! I love how you write about ‘monster girls’. So many of those stories focus on sexual stuff, but you write about them being people and how their characteristics affect them and the people around them. So much more interesting!
10470111
Monster girls need love too
Really like these story’s. Irisa Is The most interesting character I think. Figure just abuses for who she is but, that 1 scar did suggest otherwise.
This is before the Christmas themed Story then right? Reason is curious if Irisa meet Amble then.
Interesting that he keeps meeting all these monster pony’s. Main character also has the locked door I recall suggesting something but idk what or if it will appear in this story. Really looking forward to more chapters of this.
... You can't be serious.
I know that some people like night mode more than light mode, but to go so far as to show "secret" messages to one side while trying to hide them from the other is ridiculously petty. I really expected better from you.
This deserves a downvote. For shame.
10470356 What? No! I was only trying to do it because I thought it was cool. Like seeing something under a blacklight. That's all.
I just thought it would fit with the spooky Halloween spirit.
10470355 I'm glad you like the story, it does take place before the events of the Christmas themed story. I had originally intended to release this story last year, however stuff happened and I had to delay it.
Well, you'll never know unless you try. Feel free to PM your suggestion if you want to.
10470259 Well, thank you.
10470251 It wouldn't be Spooktober without a Spooky Monster Mare story. Eureka (and maybe Doctor Who) has episodes celebrating Christmas, but for me it's Halloween.
10470567
Well, that's certainly not the impression that you gave off. If you're going to hide a secret message, the first thing you should make sure of is that everyone has an equal chance of getting it. Lots of people use night mode, but almost no-one switches between the two modes when reading a story. If you had hidden the message successfully, almost no light mode user would have seen it, while every night mode user would have.
Look, I'm not mad, just disappointed. I'll remove the downvote, since it seems to be an honest mistake. Next time, perhaps use a cipher or something? That way, everyone sees it, but only the ones who try will understand it.
10470604 I mean, there's a clue to the messages presence in the story and there is even a way for Day users to see these messages that is hinted at in the same clue.
I'll change the message in the author notes to hunt as to where the clue can be found.
10470615
Thanks. I wasn't too rude there, was I? For some reason I'm a bit concerned with the wording of these particular comments.
Your pet gecko.
Cool! Now I’ll have to try your rapid story generator technique!
1. Copy a big chunk of another chapter into this one.
2. Search and swap: stallion <-> mare, he <-> she.
3. Add a couple of paragraphs at the end.
4. Instant 5000 word chapter.
5. Profit!
Seriously, though, it is great to see a new chapter in the series.
10470590
Well is there more hints that I over looked in any current stores you posted? All I recall was iries tried to go in to clean but couldn’t and informed her “master” . Most I recall being talked about really.
Main question then if it’s important are you going post something in this story soon or at all(hopefully not over several months wait for chapters). Otherwise it’s just a tease of nothing.
My theory which anyone else feel free to debate what y’all think if you recall that scene.
No answers if someone did ask just theory here, or the story/chapter that could hint to something.
1. If it’s important to him only my guess it could be something about “Family” or a past friend/partner. But then nothing really “Shocking” I think. Need reread all current story’s to see any thing may suggest that again. Mostly recall him wanting to help the diamond dog and shark pony reconnect which could suggest something.
2. Maybe he is part monster like them? Sure not all pony’s are afraid of them but a vast majority are. Nothing really suggest this though beside him taking how many he met in stride with how he acts.
10470876 Interesting theories. Who knows, maybe one or both of them are true. Just keep an eye out.
As for this story don't worry. All the chapters are done and I will be releasing one every Tuesday (if my calculations are correct) for this Spooktackular month.
10470619 Maybe a little, but I was more concerned that there was a misunderstanding than I was offended. If that makes sense.
The Wandering worm is clearly a reference to the mysterious "they".
The Glass turning is a reference to how Irisa and our MC met.
The the truth will be revealed, whether by night or by arrow. Either Luna shows the fuck up and reveals everything or our mysterious organization shows up and kills the MC, Irisa or both of them.
10471139 That is an interesting theory. Just remember that there are three more chapters for this story.
...what?
10471701 Well, this is an alternate universe and I really liked the random ship I had been given by Nailah back in the day, Filthy Rich and Trixie, so I brought it back here.
10472114
It's a first for me is all, though with Rich's taste in mares I guess it's not outside the realm of possibility
10472229 But let's be honest though, Trixie is SO much better than Spoiled Milk is.
10472720
It would be hard to find someone who isn't, though if you read the fic written by Snakeskin Ductape you get to see an au version of Trixie
*finally reading more*
I'll say, what shennanigans is this?
Did someone open a portal to the mirror world or something?
...oh...
10474159 *Shrugs* Maybe... who knows?
10474164
That would be interesting but idk how you would handle that
On the ship note, I have seen a fic where Trixie was shipped with Flutters but that part of the story went sideways
Colonel Mustard in the Library with the Dagger!
That little joke aside, for once in these murder mysteries, I'm pretty sure the butler didn't do it; Randolph was with us outside the bathroom. I'd suspect Spoiled Milk simply because she's a troublemaker, but that'd be too easy. Caramel was chatting one of the twins up so he's sus, though unlikely. My prime suspect is currently Sunshine Smiles: she seemed rather irritated with Caramel flirting with the twins, so jealousy is a possible motive there. Too many unknowns for the moment. I'm sure whatever Randolph passed to Gash Bloom is going to factor in somehow, possibly an enchanted object. Murder weapon could be that axe, but if it isn't enchanted after all like Irisa suggested, there would be blood on the bodies and floor, not ash.
This is gonna be good.
im calling it now. its all a show, their not actually dead.
plus theres no death tag on this fic. and to have actual death in the story without a death tag is a no no cuz it will trigger peeps who react poorly to scenes of death. they would want a heads up from the tags.
)
plus there prolly should have bin a warning of decapitation (even if its faked) for those who dont want to read about decapitation. (i myself can be squeamish of death scenes and would of appreciated a heads up to prepare myself for it. but no worries im not mad or anything, just giving constructive criticism
but i think the author left out the tag cuz no one dies :P
anyway i love these monster pony stories and i look forward to the next chapter! cheers!
10480113 Well, I'm glad to see that no one started screaming, "Robipony's back to writing grimdark!", Smashed the dislike button and ran, I was really worried about that.
I will say that there will be more clues in the next chapter.
10480284 Maybe...
Maybe not... 
You'll have to wait and see.
Admittedly I know that the decapitation subject might be concerning, I'm just not too sure how to warn others about it without giving away what is going on. If that makes sense.
I hope you will still enjoy the story.
10474173 I will go ahead and say that I'm not a huge fan of EQG, so more then likely it is either just a dream... Or perhaps a "window" into an alternate reality... Or a dream.
Yeah, ponies get involved in weird ships all the time. Thankfully worms are a good solution.
10480496
no worries, i am loving your fic so far!
I forgot about this, but I'm so glad I found it again
And the story takes a macabre turn. Just like all good mysteries, there are several unanswered questions at this point. I’ve got two:
Which pony screamed? The necks were severed in such a way that screaming would be impossible.
Also, why was a smart stallion like Filthy Rich was so quick to want to clean up the bodies?
Oh get it its a investigation party
Curious what’s going on but could be mystery party. Then again it’s a monster story so maybe something came along? Could be both where it’s a party first and then scare of the monster showing up at the end when everyone is calm or left.
I’m curious where this is going for the series you have going.
Wobe?
I suspected they were dulahaan or however it's spelled last chapter but this confirmed it.
And I know someone is in on it, probably Trixie.
Here i thought the twins werent really dead or they were wraiths all along
I have my guess that this is their 'trick'.
My theory
Irisa can't be it because she appears in the next story in the timeline.
Also, the twins are most likely headless mules, well, ponies. Transformations often occur in mythology at crossroads and Mr. Rich's father was involved in some questionable things. That mirror is also suspiciously in the room where the twins spent a lot of time. Trixie is also most definitely in on it. She looks angry because he might expose her and she wants this to keep going.
Irisa also now realizes that they are fellow monsters and knows what to do when one of them enters the kitchen, hence her suddenly calm demeanor.
Without spoiling anything, just tell me this has a happy ending please.
10491535 Actually wobe is supposed to be would be. Sometimes when writing on my tablet, the keyboard acts up and doesn't put in letters.
10491558
Actually I was trying to convey that Irisa is willing to protect her master and was content with sacrificing herself to save him... er... you.
10491686 Maybe... most of the stories in the series seem to have a happy ending, so it is possible. Then again, there are always exceptions to the rules. With alternate universes and timelines anything is possible, even unhappy endings.
🔪
Why do i feel like this is one big Nightmare Night prank? I mean magic and Illusions exist in equestria. I am kinda hoping its not dou.
10491535
Glad I'm not the only one who thought so.
wow very good chapter Robi!
i look forward to the next! =)
That mirror scene, I know I've heard of some type of monster that fits the bill for that but I can't recall.
Interesting read and conclusions for the party. I’m not caught up on n monsters at all beside the basic/classic I guess.
Reaction to his brother I think he isn’t around anymore or he has “changed” some how...to strong of a reaction I think when he saw him. Reasoning hard to explain typing...
His brother might been the one who requested something from him. So wtf is under the house...that door must lead to it now as a basement door or it’s the brothers room that had a secret trap door that leads down.
I also call BS on Iris not finding that slot yet behind that bread box. She seems to detail clean so, I imagine she moved that box at least once to clean underneath or around it. If she did before hearing the breathing early on I’m sure she check the hole then.
That slot sounds like it always open and just blocked by the box instead maybe having a door or something on it
Ires is the moth I guess but I suck at those hidden riddles at the end.... do they reference your plan on the story or hint something bigger?
Delicious.
I hope to see more of the twins.
These "white rooms"... It's been so long since I've read Jag's story that I forgot she had mentioned them. I'm starting to wonder if it's some kind of facility where various "test subjects" (dunno if they're willing or not) are experimented on via magical means or otherwise. Or perhaps they're just created outright from said experimentation. Either way, considering Iris/Irisa's fear of the place, it's easy to assume that this facility is not at all above board and certainly not ethical in the least. I'm interested in learning the purpose of these mysterious white rooms.
All in all, another great story, Robi. Can't wait to see what you come up with next.
Dunno if you're in the market for suggestions, but I think a djinn could provide an interesting hook, considering the rather unique sort of magic that comes with being one.
10502508
I imagine these pony who run the ‘white room” are like SCP foundation. More for monster pony’s probably just not as hightech. Possible kidnap the monsters seeing as ponykind know about monster but, don’t see many. Doubt it’s with the Equestria government (or could been at 1 time) so probably just a group running them self.
Senior Rich may have 1 time been apart of it Now that I think about it. Mostly it’s weird he made and appearance and his lines with that book backing it up. Just putting that theory out there
