Becoming Professor Moriarty’s Probability

“Heh.”

“Ahhhh…”

Forcing the fragile body of Mycrony to the ground, Isaac Adler, who had sunk his sharp fangs into her neck, carefully withdrew his head back.

“Miss Mycrony.”

“………”

“What are you doing right now?”

Wiping the blood from his lips, Adler looked at her cautiously.

“… While trying to tame a cute vampire, I let my guard down and was totally subdued in the process.”

Mycrony, who had been holding Adler tightly with her legs up all the while, responded in a shy voice while avoiding his gaze.

“Moreover, despite struggling hard, I was destined to be bound by the dominating power you’ve concealed all this time.”

“………”

“It truly was a tragedy that occurred in the blink of an eye…”

Isaac Adler looked down at her with an incredulous expression.

– Mr. Devil, there’s no sign of the guards leaving the restaurant.

– Did they abandon their master? Those fools are really out of their damn minds.

– The master must have cast a spell on them!

Different voices of his subordinates reached Adler’s ears simultaneously.

“… What are you doing?”

As Adler lay momentarily dazed due to the conversation going on in his head, she observed the phenomenon and immediately changed her tone to a slightly colder note.

“If you keep spacing out, I’ll throw you off.”

– Groan…

Contrary to her words, more strength went into Mycrony’s legs which were wrapped around Adler’s waist.

“Well then…”

Although cold sweat began to trickle down his forehead, Adler, who couldn’t back out now, began to lower his head slowly again.

– Swoosh…

But perhaps due to the immense strength in Mycrony’s legs…

“Oh my~”

Adler’s head, which had gotten much closer to her body than before, was obstructed by Mycrony’s ample chest, failing to reach her neck.

“I guess there’s no choice.”

“………”

“Instead of the neck, I’ll have to drink from here.”

Mycrony murmured, looking at him with wide eyes.

“While it would be thrilling to die from excessive bleeding when bitten on the neck again by those cute fangs of yours, that’s not why you’re here now, is it?”

“Listen…”

“In order to facilitate a head-on confrontation between my sister and the professor you serve, you aim to capture me first, as I’m the most threatening third force involved in the grand scheme of things…”

She turned her head to the side, her expression pitiful, her tone like that of a sorrowful heroine.

“Alas! I should have realized that a bit earlier…”

Then there was utter silence.

– Sigh…

“… Uh.”

As Adler sighed and bit into her plump flesh. In response, Mycrony Holmes twisted her body, letting out a faint moan.

“……….”

Just how much time had passed like that?

– Shimmer…

A unique red-coloured, bat-shaped seal, different from other women he had enslaved, started to appear on Mycrony’s lower abdomen.

“Wow…”

Mycrony, who had been biting her lip hard enough to leak blood already, whispered softly as she looked at the scene before her.

“It finally happened.”

“………”

“My life is over now.”

Of course, her face, flushed with pleasure and glee, didn’t look like that of a woman whose life was deemed to be over.

“Just a few hours ago, the entirety of England was in my grasp. Now, I’m merely a possession of a single boy…”

“… Sigh.”

“I’m so sad that I could cry out a river of tears.”

Looking down at her with another sigh, Adler finally spoke in a quiet and subdued tone.

“You might react this way now, but you will certainly regret it later.”

“Will I?”

“I’ll return all the insults I’ve endured so far.”

“… Uh?”

As he gently stroked Mycrony’s lower abdomen, a tingling sensation began to spread throughout her body, making her quiver violently.

“What is this?”

After quivering for quite a while, she asked in a faint voice.

“… You’ll come to understand everything, in due time.”

Adler replied to her in a soft and mellow tone, poking her lower abdomen with his finger.

“So, relax your legs.”

“… Ugh.”

Upon his words, Mycrony’s legs relaxed by themselves, without her will.

“Prepare yourself.”

Adler, who had momentarily touched her twitching waist, murmured while caressing her chin as she lay powerlessly on the floor.

“… I’ll thoroughly clean the space below my desk back in my hideout.”

Then, leaving those words behind, Adler began walking towards the front door.

“… Sigh.”

As the twitching in Mycrony’s lower abdomen subsided, she released a hot and sensuous sigh and spoke softly with a gentle smile on her face.

“When going to my sister’s house, you’ll need to be especially careful not to run into Inspector Lestrade .”

“………”

“In the past few days alone, she has taken down at least five back alley gangs while looking for you.”

Adler flinched slightly at those words, murmuring to himself as he quietly stepped outside the room.

“… Sometimes, I really resent this curse of mine.”

As the front door closed, a silent stillness began to flow within the room.

“… Miss Mycrony.”

“Hmm.”

Despite several minutes passing, Mycrony Holmes just lay there blankly on the floor.

“What on earth has become of you?”

Her gaze turned to the captain of her personal guards who had quietly entered the room through the front door.

“I was tricked by an evil vampire who has clearly misunderstood the nature of the curse he has.”

“I don’t understand.”

“What do you mean?”

“Why on earth would you intentionally do such a thing?”

The captain of the guards, who spoke those words, trailed off in her speech.

“Maybe it’s because I hadn’t felt anything for over 20 years?”

“………”

“My threshold for stimulation has become a bit too high.”

Mycrony Holmes, whose eyes had become listless, murmured in a dazed voice.

“Now, simply biting my neck is no longer sufficient for me.”

“Are you serious?”

“Being bitten by Adler on the weekends feels so vivid that my brain tingles just at the mere thought, but the lethargy I feel during the remaining 5 days has more or less doubled.”

At her words, the captain of the guards stood silently, unable to respond.

“I wish I’d never known this feeling, but once you experience something like that, you can’t ever stop.”

“Sigh…”

“But even so, stepping forward to claim Isaac Adler myself is far too bothersome.”

She extended her hand, lifting the still-slouched Mycrony Holmes to her feet.

“But, what if he were to control me himself?”

“Stop murmuring and sit up properly.”

“There’s no need to truly possess him, I can relish a variety of sensations through this method alone.”

Then, the captain, like dealing with a stray cat trying to slip away from her grasp, sat Mycrony down on the sofa.

“So, you chased away all the guests from the mansion and caused this whole mess just for that reason?”

“Ah, don’t worry about that. The people who visited today weren’t guests but professional actors I had hired.”

“What?”

The listless Mycrony, sprawled on the sofa, began her story with a hint of a smirk on her lips.

“The reason I hid Isaac Adler under the desk and covered him with my clothes was precisely due to that. Being in the same profession, there was a high chance that he would be able to recognize them at a glance.”

“… But isn’t that just what you usually do?”

“Just take it as it is.”

She brushed off the question carelessly, then touched the lower part of her belly with a satisfied expression on her face.

“Having acquired this cute mark that gives me a sensation different from pain, I’m more than a bit content already.”

“So, you’d risk putting the entirety of England into Isaac Adler’s hands just to gain that peculiar mark?”

At the piercing remark of the frowning captain of her personal guards, the corner of Mycrony Holmes’ mouth lifted subtly.

“Of course not.”

“Pardon?”

“Despite what it may look, my patriotism is quite profound, you know?”

The next moment, her lower abdomen began to glow quietly.

– Shhhhh…

“………!”

When Mycrony Holmes touched her abdomen again in that state, the distinct bat-shaped mark disappeared as though erased.

“What… did you just do?”

“I tried to mimic what Adler did.”

In front of that spectacle that completely defied the established magic system, the captain of her personal guards asked with widened eyes.

“According to my observation, he doesn’t simply just use magic, but rather manipulates the whole linguistic system that constitutes magic itself.”

“What are you saying?”

“I became curious and did a bit of research. I found a way to easily neutralize most persistent magic that way.”

However, the explanation that followed was a bit too complicated for the physically-oriented woman.

“If it had been the magic of contracts designed by him, I might have had trouble in neutralizing it fully. But this is just a regular vampire’s seal.”

– Buzz…

“Yes, that’s it.”

Yet, without a care, she continued murmuring to herself, making the seal on her lower appear and disappear repeatedly, displaying her full control over the seal.

“I’ll keep it deactivated usually, and activate it only when meeting Adler.”

“So…”

“It’s what you might call carefree pleasure.”

Saying so, she tapped her belly with a satisfied expression and closed her eyes.

“… Keep it a secret from Adler, okay?”

“……….”

“Just imagining him confidently climbing on top of me, thinking he has me under his control with just that cute seal, gives me the chills.”

Soon after, as those words spoken in an entranced voice left Mycrony’s lips, the captain of her personal guards nodded silently and then exited the room.

‘… Is London really going to be alright at this rate?’

As she headed to the place where her subordinates were waiting with heavy steps, a rather fundamental question about the safety and security of her homeland rose in her mind.

That evening, in front of 212B Baker Street…

“… I’m a bit late.”

Pressing the hat he bought from a tailor shop deeply on his head, Isaac Adler looked around and then quietly adjusted his attire as he moved forward.

– Knock, knock, knock…

And then, Adler began knocking on the boarding house door, taking a deep breath.

“Are you here to see Holmes?”

“Ah, yes.”

Wondering how he should react if Watson were to suddenly appear, he sighed in relief at the sight of the kindly smiling Mrs Hudson and nodded his head.

“Go up to the second floor.”

“Thank you.”

“… She had been waiting for someone for a while, I think it might have been you.”

As he passed her and started to ascend the stairs, Adler paused slightly at her words.

“Do you know the reason?”

“… I’m not sure.”

Following his question, Mrs Hudson responded with a look of genuine uncertainty.

“When she came into the boarding house this morning, she had a large bouquet and a small box in her hands.”

“………”

“Do you think it might be related to a case?”

At that suggestive remark, Adler quietly bit his lip and resumed walking forward.

– Knock, knock, knock…

After hesitating for a moment, he began knocking on the room’s door.

“Miss Holmes.”

“……..”

“It’s me, Isaac Adler.”

However, for some reason, there was no response.

“Miss Holmes?”

Tilting his head slightly, Adler knocked again and soon put his hand on the door handle, trying to open it.

– Creak…

Then, the door slowly opened.

“I’m coming in…”

Briefly gauging the situation, Adler stepped inside, but the moment he moved a step forward…

“Huh?”

He was met with a sight he had not at all anticipated.

“……….”

“Charlotte…?”

Charlotte Holmes lay collapsed right in front of Adler.

“You’re not a kid anymore, why would you play such a pra…”

For a moment, Isaac Adler silently took in the scene before him, then lowered his head with a smirk.

“……..”

However, not long after, his face began to stiffen.

‘… That ivory box.’

Beside the bouquet that she held dearly in her embrace, there was a familiar box conspicuously placed on the ground.

‘It’s from the Dying Detective episode, that thing…’

Adler, noting the sharp spring sticking out from the opened box, hesitantly checked Charlotte’s hand.

‘It’s got to be a ruse. Surely she wasn’t pricked…’

Yet, there was a clear wound on her finger, as if pierced by a needle.

“………”

Holding the pale-faced Charlotte in his arms, Adler’s eyes began to tremble more intensely than ever before.

“This can’t be real.”

“… Hm.”

At that moment, he missed the very faint twitch of Charlotte’s lips and the blush that had risen to her cheeks.
