Becoming Professor Moriarty's Probability

Around the time when Jane Moriarty and Gia Lestrade received the error-filled suspicious message, hastily composed by Adler,

- Squeeze…

“What are you doing?”

As Charlotte sat atop Adler’s stomach, flashing him a dark smile, she abruptly gripped his hand before questioning,

“Oh, that… Well…”

“My, my hand was itchy, so I was scratching it…”

Under her watchful gaze, Adler looked at her with an anxious gaze before murmuring in a low voice. Unease oozed out of his every action.

“… Really?”

“Mm.”

“Look me in the eye and tell that to me again.”

However, as Charlotte leaned forward, her voice chilly and her gaze looking down at him, Adler’s attempt at composure crumbled and his eyes rolled in a dizzying fit of nervousness.

“Are you lying again?”

“No, it’s just…”

“Adler. Do you hate me?”

Observing his flustered response, Charlotte’s voice grew even darker as she posed the question, her words heavy with implication.

“Is your hatred for me so strong that you would call out to an old hag, who has lived for a few centuries more than you, who doesn’t feel the slightest bit of love for you, who rapes you daily out of possessiveness and a desire to control and dominate you…”

“That

“Then why were you secretly sending messages with your hands hidden behind your back…?”

Adler, attempting to extricate himself from the situation by twisting and turning his body, realised that Charlotte was using her mana to pin his body down and there was nothing he could do to get out. Frustrated, he closed his eyes and sighed in resignation.

“… Let’s be real here. What even is the difference between you and the professor?”

“…..?”

“It’s the same forced situation…”

Adler’s voice trailed off weakly.

“Adler, what are you talking about?”

Charlotte, blinking rapidly as she listened to his last desperate attempt, tilted her head curiously while gazing down at him.

“Do you really not understand the difference?”

At her statement, Adler, quietly observing her reaction, shook his head from side to side.

“Haa…”

Charlotte, exhaling softly, whispered the explanation directly in his ear.

“To start, the Professor doesn’t love you now, does she? Yet she forces herself upon you to prove you are her possession.”

“That’s, actually a bit different…”

“Furthermore, you do love me, don’t you?”

Charlotte’s voice was eerily calm, but the look in her eyes, dark and abyssal, suggested a different emotion.

“Our relationship is different from the twisted bond you share with that monstrous lizard. I love you, and you love me too.”

“…”

“Isn’t that right?”

Charlotte continued explaining her side, however, when she received no response from Adler, her eyes narrowed and he gazed ominously at him, demanding a response.

“Y-Y-Yes.”

“…”

“… I love you.”

With a terrified look in his eyes, Adler muttered those words and then slightly blushed, turning his head to the side. Seeing that, her eyes finally regained their light.

- Haaah…

“… Huh!?”

Eventually, in that state, she bit Adler’s neck.

- Nibble, nibble…

“Wait a minute…”

- Slurp…

After burying her head in his neck and nibbling on Adler’s skin for a while, Charlotte slowly raised her head and wiped her mouth with her sleeve.

“… Moreover.”

Then, with a more tranquil gaze, she added to her explanation.

“You were the one who seduced me first.”

Hearing that, Adler had nothing to say anymore, so he shut his mouth.

“You were the one who approached me first when I was investigating a case. Not to mention, you were secretly in love with me even before our first encounter.”

“…”

“You confessed your love to me before anyone else, and it was you who dyed my pupils in your colour. Your pupils have also dyed in my colour as well.”

Charlotte’s voice gradually heightened with each word she spoke.

“… And you were always up to dirty things, pouncing on me, sucking my blood, biting my neck while flirting with me whenever you could. And when I showed a bit of sincerity, you would just smirk and run away from me.”

“Um, I didn’t do those dirty things…”

“Shut up. And as soon as I started to like you, treating me like I was a ghost, you began paying more attention to other women…”

Her eyes flashed fiercely, and Adler, who was about to make excuses, chose to remain silent.

“But now… finding a way to bind you, how is that any different from that monstrous lizard?”

“… Isn’t that too conscienceless?”

At that moment, Charlotte’s black aura started intensifying to an unimaginable degree.

“Right, right, how about we have a cup of tea and talk like civilised people?”

“I think this beastly way of conversing is still a bit early for Miss Holmes.”

Feeling the ominous energy seeping into his body, Adler broke into a cold sweat and began his final protest as if grasping at straws.

“I’ve just enrolled at August Academy this year. That means I’m legally an adult.”

“Hmm…”

“But Miss Holmes is younger than me. Although I don’t know your exact age… So… uh, um…..”

Realising the loophole in his words, Adler soon faltered and eventually clenched his eyes shut and blurted out whatever came out of his mouth.

“… This is a crime.”

“Is a criminal consultant using the fact that they shouldn’t commit a crime as a reason?”

Charlotte’s cold voice immediately pierced Adler’s ears,

“Even criminals have their own philosophy. I don’t mess with kids…”

“… And yet I see that you’re doing a fine job raising Celestia Moran.”

Hearing that, Charlotte scoffed in a small voice. However, seeing Adler’s puzzled expression, she sighed and muttered.

“Or, it may be the other way around it seems…”

“I don’t know what you mean, but you understand now, right? It’s just not possible…”

Smirking devilishly at Adler’s hopeful remark, Charlotte began rummaging through his pockets.

- Swoosh…

“What is that?”

Finally, she pulled something that looked like a business card from her pocket and waved it, causing Adler to tilt his head in confusion.

“Student ID.”

“What?”

“I finally completed the enrolment process at August Academy a few days ago.”

Then, as she reverted to her usual tone with a sly smirk, Adler froze completely.

“I almost wasn’t able to get in this year due to a certain meddlesome professor?”

“Uh…”

“But recommendation letters from two separate queens did the trick… no, one of them is Empress now, right?”

“Wait a minute. Are you saying…”

As he looked up at Charlotte in disbelief, she whispered into Adler’s ear in a calm voice.

“… Since I’ve enrolled at August Detective Academy, I’m now an adult too.”

“That’s absurd…”

“The law says so, Mr Adler.”

“I will file an objection. You must have altered the documents, right? It’s obvious the officials didn’t check them properly…”

“I didn’t want to say this but…”

Despite Adler’s persistent nagging, Charlotte lowered her gaze and whispered to him with a bone-chilling smile,

“I didn’t know you were so fond of the law, so let me tell you an interesting fact.”

When her next words reached Adler’s mind,

“… According to the constitution of the British Empire, you can’t even be considered a human now, can you?”

“Whatever I do with you now… the laws that apply to humans don’t apply to you…”

It completely shut down, leaving him with no further excuses he could use.

“So, do you still have something to say?”

“Sa-Sa…”

“… Save me?”

That was all Adler could muster while he stared at Charlotte, who began stroking his cheek in the meantime, with clear terror in his eyes.

“Please be gentle…”

And then he uttered his last words.

“What to do…”

Meanwhile, Charlotte who blinked for a moment after hearing his pitiful request,

“… I’m not sure I can pay heed to that request.”

The moment she began unbuttoning her coat with a sinister smile,

“Just a minute!!!”

As if he had hit a home run in the bottom of the ninth innings, Adler, with eyes wide, stretched out his hands and urgently raised his voice,

“I, I had forgotten about something…!”

“Why? Do you still have a reason?”

Charlotte, looking at him with a puzzled expression, soon twisted her expression quietly.

“I, I have a terminal illness? I’m dying in just six months…”

“If you do this now, I won’t be able to take responsibility now, will I?”

And with that silence drenched the room.

“… Have I not yet explained the final reason?”

In the silence, Charlotte finally opened her mouth after staring at Adler for a while.

“Unlike that lizard, who can hardly get pregnant as she’s a different species altogether, I can become pregnant with your child right away.” 𝚏𝗿𝗲𝐞𝐰𝚎𝕓𝐧𝚘𝘃𝗲𝐥.𝐜𝚘𝕞

“Did you, did you not hear anything I said? In six months I…”

“That’s why I’m doing this.”

Her voice was eerily calm.

“At first, I thought about killing myself to save you.”

“That, that’s…!”

“But then, I thought you would live in misery forever if I were to do that.”

Her expression did not mirror the calmness in her voice, however.

“So, I will embrace you.”

Engulfed in a darkness blacker than ever before, but with a smile brighter than he had ever seen her make, Charlotte continued,

“I’ll carry your genes, combine them with mine… and give birth to a child who resembles you.”

“Um…”

“And I will raise the child wholeheartedly all my life, remembering you.”

“That’s the ending I’ve chosen for us.”

With that, her speech ended and a brief silence descended between the duo.

“Shall we move somewhere else then…?”

“Let’s do that. I was planning to confuse our location to evade detection anyway.”

Realising that he had gotten it all wrong amid the silence, Adler, trying to buy some time, threw out his suggestion which Charlotte gladly accepted.

“And maybe we could go on a date for a day, and take it slow…”

“Haaah…”

However, his overtly frank remark led Charlotte to sigh quietly and speak again.

“Choose one of the two.”

“What, what do you mean?”

“… Do you want me to fuck you like a dog right here and now? Or shall we go to a love hotel and make love as we lovingly embrace each other?”

That statement was enough to completely freeze Adler’s thinking process.

“Please, be gentle…”

Nevertheless, hoping for some unexpected turn of events while moving, Adler finally muttered.

“But as I said before, I can’t guarantee that request.”

Regrettably, contrary to usual circumstances, no variables occurred along the way as Adler and Charlotte checked into a room in a nearby love hotel.
