Becoming Professor Moriarty's Probability

0% “... Ugh.”

I clutched my throbbing head and opened my eyes.

Right, what happened this time? Honestly, I’ve been through every kind of crime imaginable, so I doubt anything could faze me anymore.

“Ah, hello.”

“... Ah. Haha.”

I steeled myself with those thoughts, but the moment I opened my eyes and saw the scene before me, I had to force back the urge to close them again, forcing a smile instead.

“Are you awake?”

The queen, who was supposed to marry a prince from another kingdom in a few days, lay naked beside me.

... It couldn’t be helped.

Well, to be honest, I half-expected something like this to happen the moment I hastily drank that wine.

To think that even on a trip meant to escape my predicament, I had to sell my body in exchange for safety— is this really how things are supposed to be?

Am I even worthy to be a man...?

At this point, I’m starting to wonder if I’m really Isaac Adler or if I’ve been deluding myself into thinking I’m someone else entirely.

“Ugh.”

As I sat there lost in such pointless thoughts, the queen (who had apparently been staring at me intently until I woke up) finally got up and stretched, muttering to herself.

“... Ugh, my stomach feels so queasy.”

Watching her rub her lower abdomen like that made my face heat up for some reason.

... Does this woman not age at all?

I’m not sure how much time has passed since I first got caught up in this mess, but the queen’s face still looked exactly like it did when she was a princess.

Well, I suppose it’s nice to have someone pretty taking care of me, especially since I’ll be indebted to her for a long time.

This idiot still hasn’t come to his senses, huh?

“......!?”

Just as I was thinking that, a familiar translucent window suddenly appeared before my eyes.

You’re really something, you know that?

... Miss System?

The system, which hadn’t appeared since I cleared the game, suddenly popped up after years of silence.

Why now...?

I was planning to leave you alone, but seeing how you’re living, I couldn’t help but feel sorry for you.

As much as I found the reason for its sudden contact irritating, I realized I needed the system’s help in this situation.

And honestly, the only reason the system would contact me out of the blue like this was probably because of that.

Well then, let me show you your fate for old times’ sake.

Warning! – Probability of being captured within 24 hours — 74% – Probability of being transported to a secret hideout within 7 days — 99%I had expected it, but seeing the probabilities laid out before me was still shocking.

“W-Why...?”

Even if we ignore the professor and the detective, you’ve turned even your closest allies into enemies, and now you’re having an affair with the queen, and you’re asking why? Wow, you really haven’t come to your senses after so long, huh?

The system’s tone, now filled with emotion and sarcasm, made me miss its old, dry manner of speaking. But that wasn’t the issue right now.

I needed to get out of this country immediately. If I didn’t, then...

Even the queen might get swept up in this madness.

Thinking about it now, the only people on the side of justice in this terrifying conspiracy were Charlotte and Gia.

The rest were villains who would likely kidnap me and harm the queen.

So I couldn’t stay here any longer. If I did, it’s not just the queen who’s in danger— this entire country could be at risk...

Wow, look at you, ready to abandon everything the moment you find an excuse.

... Why have you become so much more aggressive than before?

Shut up, you’re the kind of person who’d make even an incubus cry in defeat.

Just as I was about to get up and start packing, I frowned quietly at the system, which continued to act aggressively.

Wait, what are you doing?

I’m trying to close the system.

No, wait. Are you serious?

The moment I reached out to swipe it away, the system dodged to the side in a panic, its voice flustered.

I-I might have been a bit harsh, but I can still help you in many ways...

As expected, even though I didn’t know what kind of being was behind the system, I could definitely figure out its personality to some extent.

The system was probably an extreme tsundere.

I have a plan, you know.

W-Wait a second...

And I hate being controlled by others more than anything in the world.

The problem was, currently, I was not in a position to carry out an escape while considering such a personality.

Especially by women.

With those words (of course, spoken only in my mind), I grabbed the system window and swiped it closed. Then, I slowly got up and sank into thought.

If I want to end this situation, I have to return to the Auguste Detective Academy. The special resources there are my only hope.

The problem was, that the Auguste Detective Academy was in London, the very place I fled from.

In other words, to go back, I’d have to somehow escape the clutches of the madness-driven conspiracy of the deranged women surrounding me.

“... Hey, Adler.”

Just as I was about to take a step, lost in thought.

“Are you leaving?”

The queen’s lonely voice came from behind me.

“Ah, that’s...”

“You don’t need to make excuses. Just looking at your face now, I think I know what you’re about to do.”

I tried to offer an excuse urgently, but it seemed the Queen had already noticed something.

“Perhaps, this will be the last time we see each other?”

“......”

“Even so, I’m satisfied. Now I have a way to remember you.”

To be honest, for me, who had lived a life of being obsessed over by someone else my entire life, the Queen’s reaction was quite unexpected.

“I had a carriage prepared in advance at the exit of the palace’s secret passage. If you leave now, you should be able to reach the border before nightfall.”

If I weren’t stuck in this situation, I might have liked to stay by the Queen’s side a little longer.

Of course, I couldn’t do that now. I had to leave this place quickly, both for her sake and mine.

“Your child, whether it’s a boy or a girl, I’ll raise them well and make them the ruler of this country.”

Watching the Queen stroke her lower abdomen again as she said that, a bitter smile inexplicably leaked out.

Could it be that this person was raised too preciously and didn’t receive sex education?

The probability of getting pregnant during the fertile period is surprisingly only 20 to 30 percent.

Especially in this world, in the case of different races like me, the odds were even more abysmal.

Even the professor developed a special magic to solve the racial difference issue.

So, perhaps the Queen’s chance of getting pregnant from this encounter was about 1 percent at best?

“... I, I love you. Adler.”

Nevertheless, I quietly shut my mouth and, leaving the Queen whispering so from behind, started heading for the door.

Yes, this would be a better ending for both the Queen and me.

If this relationship were to be discovered, the Queen would certainly be ruined.

Instead of that possibility arising, I hoped she would be satisfied that her first love took her first experience.

“B-But, I have one last question.”

Just as I was resolved to do so and grabbed the doorknob, a slightly trembling voice suddenly came from behind.

“This golden tattoo... How do you erase it?”

“.......”

“Oh dear. If my fiancé sees this, it’s going to be quite troublesome...”

Turning my head at those words, I finally noticed the golden seal that had appeared on the Queen’s belly, and for a moment, my mind went blank.

... Wait, could that be?

Originally, the seal I engrave doesn’t have a heart filled in the middle.

Because the meaning of the heart filled in the middle was...

“W-Wait a minute. Adler?”

“... Hah hah.”

“H-Hey!”

It seemed I needed to leave this place as soon as possible.

About a month after Adler left the Austro-Hungarian Empire at an incredible speed,

“Y-Your Majesty! Please take a look at this!”

“... W-What’s going on?”

The Queen, who was sipping herbal tea in the garden with dark circles under her eyes, was startled by the maid rushing to her and asked in surprise.

“It’s about the prince who came for marriage talks but suddenly lost contact. It’s in the newspaper now...!”

After receiving the newspaper from the maid and staring blankly for a while, the Queen raised her voice with wide eyes.

“... He met a storm and fell off his ship to death?”

“Yes! And apparently, he was the only casualty. How could such a thing happen...?”

In fact, unbeknownst to her, she too had been born with a curse like other women around Adler.

The Queen’s curse was that it led those who proposed to her towards death as payment for having absurd luck.

It wasn’t a coincidence that many of her marriages were ruined by unfortunate accidents, or that she became the head of the Empire from being the queen of a minor state like Bohemia, or that only succeeded in relationships initiated by herself— like with Adler.

“This is terrible... how could this be...? Wait, maybe...”

Naturally unaware of these facts, she began rational suspicions as she recalled Adler’s face.

“Ugh.”

“Your Majesty? Are you alright?”

But then she suddenly started retching violently.

“G-G-Guhkkk... Ah?”

As she gestured to stop the maid rushing towards her in alarm, she broke out into cold sweats and muttered,

“I’m in big trouble.”

“What do you mean?”

Her curse – absurd luck – was triggered a month ago on that fateful night she had experienced with her beloved. In exchange for that trigger, she had swallowed the life of the man who had tried to possess her against her will, and the engagement ring said man had painstakingly obtained for her.

“... If things go this way... there won’t be anyone left for me.”

Thus began what would become known as The Bohemian Queen’s Pregnancy Scandal, with the potential to ignite World War I.
