If my calculations are correct,

in a minute you'll see a man at the crossroads

who doesn't know where to go.

Ira!

Ira!

A girl?

Vitia?

Vitia.

Vitia!

Hello. It's General Sosnovskiy. Send an ambulance now.

What shall we do with Vitia?

To the precinct.

Hi.

It's so cozy here.

Katia, do you know that some people call Sudoku puzzles magic squares?

They are wrong.

The Sudoku is a nine-order Euler square.

The number of possible combinations in a standard square

is over 6,000,000,000,000,000,000,000.

If you solve one Sudoku puzzle a day,

you'll need around 19 million years.

I see you're doing okay.

What do the doctors say?

At present, both the mother and the baby are in no danger.

But you must realize that Anna Nikolayevna needs to take care of herself.

I'd like her to stay here for a few more days.

Why?

For observation

I want to keep my head on my neck.

What do you mean?

The general called.

I don't remember the name.

Sosnovskiy?

Sosnovskiy.

So he said to me…

I'm sorry. I didn't ask for this.

But in case something happens…

In case something happens, you'll have my head.

That's not what I meant.

Please keep me posted in case something happens.

-Of course. -Thanks.

I brought you oranges.

I'd prefer coffee.

Are you sure you can take it? Doctors don't recommend it.

A recommendation is not mandatory.

I want coffee very badly.

I thought she was mute.

No, it's like in that joke – there was no need.

Come on, lift your feet.

You're doing it wrong.

Really? Why?

A spider's net has to be built inside out.

We don't have cobwebs here.

It's the basics of minimizing the potential energy.

Step aside.

You mop five square meters in one go,

then go back to the bucket to soak the mop.

This ward is around 25 square meters.

So it makes five repetitions.

And you put the bucket at the door. It's stupid.

You have to walk 42 meters all in all.

If you placed the bucket in the barycenter of the ward,

you'd have to walk 15 meters less.

Fifteen?

How many wards do you have?

Thirty-five.

So it would save you half a kilometer a day.

Why didn't you say it earlier?

There was no need.

Like in that joke.

Right.

Like in that joke. By the way, what the joke is?

THE MOP 2

Knock-knock.

-Hi. -Hi.

Enough. You are strangling me.

Nikolay.

-Thank you. -They are Peruvian lilies.

-Where is my coffee? -You can't have coffee.

Let me put them in a vase.

You're in cahoots.

They have no smell. I'll need to do a test.

Katia, they are Inka lilies, specially for pregnant women.

They don't have a smell. They are hypoallergenic.

-It's a special kind. -Yes.

How are you?

Good.

Minimizing the cleaning lady's energy.

Great.

How is Vitia?

Good.

Good isn't a mathematical notion.

Ania, I don't know what's the mathematese for good.

To hell with mathematics. What's going on?

He was detained.

You…

You arrested your own son?

I didn't arrest him. He is detained.

Have you questioned him?

-He wouldn't talk to me. -So you put him in jail.

I didn't put him in jail.

You put him in jail.

No.

Dad has settled it.

There will be no record,

and Vitia will officially work for his office.

It'll be counted towards his army service.

I don't understand. What were all these attacks about?

Ania, a group of teenagers, idiots…

A relapse, hormones…

Yes. That's what Fatum said. What about that girl?

That Ira, Vitia's…

She dragged him there.

What happened to her?

She left the city.

Right.

General Sosnovskiy took care of everything.

How does Vitia feel about her leaving?

Ania, I don't know.

What do you mean?

He doesn't talk to me. He is silent all the time.

What are you doing?

You know why he is silent?

There is no need to talk.

And no sense, either.

Where are you going, Ania? Ania, you…

Did you see that? How am I supposed to deal with her?

Talk to her about her pregnancy, woman to woman.

You share a common language.

The doctor said she should stay for a couple days.

I understand. But you shouldn't worry too much.

I'm trying.

-Okay, bye. -Why? We'll give you a ride.

I have already called a cab.

-Okay, bye. -Go, go.

Ania.

Katia?

-Yes. -Sosnovskaya?

Ira Kachalova?

Yes.Hi.

Hi.

How long has it been?

-Since the prom. -Right.

You are pregnant!

Right. It has been too long since the prom.

Katia! You're a godsend.

What do you mean?

Your father is a big shot in the secret service, right?

-A colonel or lieutenant colonel. -He is a general now.

As I said, you were sent to me by God.

What happened?

Someone is trying to kill me.

I'm not crazy. You don't believe me?

Wait.

What are you doing here?

-I hope you're okay. -I'm fine. I was visiting a friend.

Why don't we go to a café, and you'll tell me everything?

No.

I can't right now, sorry. I'm just… in shock,

and I don't trust anyone after all that.

After what?

Please don't ask. But it's really serious.

Okay. So you will only tell my dad, right?

Yes. Can you arrange a meeting or me?

Okay. Give me your number. I'll call him.

Here. All my contacts.

Help me.

Okay. I'll try to set up a meeting for you.

I need to go.

-I'll be waiting for your call. -Okay.

Shall we have a drink? Shall we talk?

So, Vitia,

mathematics demands abandoning all other parts of life.

I don't know any big mathematician who was happy in his private life.

Believe me, no sex, drugs, or rock-n-roll

can compare to the high

of solving an integral of a complex function

through residues.

For me, there is nothing more beautiful

than Euler identity or the Gaussian integral.

People say diamonds are forever.

The Pythagorean theorem is forever.

Let's take Taylor's series…

and move to the complex plane.

Replace X with EX and write it out.

Go on.

Dad, please.

She said she'd only talk to you.

General Sosnovskiy, do you even love your daughter?

What does the maternity leave have to do with it?

Okay, I'll think about it.

Yes. I promise.

Thanks, Dad.

Thank you.

Bye.

Did he say yes?

Yes.

So general Sosnovskiy does love his daughter.

Love is when someone cares more about you than about the cat.

Kitty, kitty!

Kitty, kitty!

The back, too.

One, two, three.

Ania.

I was going to talk to you yesterday.

He solved it. It's the correct solution.

Vitia is a genius.

Do you love something apart from your mathematics?

Coffee.

What else would I love at this early hour?

Yes.

Mathematicians make jokes, too.

Bad jokes, especially when they are pregnant.

Good morning.

How do you feel?

Quick, quick, slow.

Good.

Good.

Good morning.

Hey.

Good morning.

Ania said you solved it correctly.

Did she?

Good job.

Just how you like it.

Chamomile tea…

I got it.

Buckthorn jam.

I also stopped by at the bakery

and got you some fresh…

oatmeal…

Your favorite.

Like when you were a little girl. You wouldn't go to bed without it.

"I want cookies!"

Dad, I love you.

Well…

What about your Kachalova?

She wouldn't pick up her phone.

You know, she looked really scared yesterday.

I took it lightly then, and now I'm scared.

Yes.

Yes.

When?

Got it.

What is it?

Yesterday, when you asked me to meet with this Kachalova,

I told my guys to collect information about her.

What did they find?

They found her…

body.

Just now.

Just don't get upset. Please.

A suicide?

Probably. Or she was pushed.

ID?

Yes. That's how they recognized her.

Irina Kachalova.

Yes, it's her.

She lived her on the 19th floor.

She jumped from there.

Or someone pushed her.

What do you think?

Yes, Mitia.

If it's about the body on 13, Lomonosovsky Ave., I'm already here.

I'll explain later.

Weird. She is already at the scene.

Maybe by accident. Although…

Yes, although. By the way, how is the Mop?

Not bad, you know.

She talked to Vitia in their bird language yesterday.

He even said hi to me this morning.

The cat pissed in my sneakers this morning.

Seriously?

-Why are you telling me this now? -I don't know.

It just came up. By accident. Although…

Yes, although. I think it's this way.

Hi, everyone.

What have we missed?

It's Ira.

Remember, I told you how I ran into her yesterday by accident.

She was supposed to meet with my dad today.

She never did, I gather.

She never did.

Looks that she really should have.

Are you going to fill me in? No?

They have opened Kachalova's apartment.

Let's go.

Thanks.

The apartment was locked from the inside.

No signs of breaking in.

Mitia, go upstairs. Have a look around.

Okay, Katia, talk to me.

How long has it been since you last saw her?

Maybe 15, 16 years.

It was at the prom.

We weren't very close.

We hang out, gossiped…

We even once drank a bottle of pink champagne in the toilet.

So you haven't seen her in all these 15 or 16 years?

No, not once. Not even a phone call.

What about these… class reunions?

I've never been to them.

I was going to a couple times, but there is always a body or something.

So how did you meet after all?

By accident.

Yesterday, while I was waiting for a cab.

After you and Ania had left.

It was by accident.

Did she say what she was doing there?

She works there.

As a doctor?

No. She gave me her business card.

Foundation president…

Irina Kachalova.

Anna Nikolayevna…

Anna Nikolayevna, I wanted to apologize…

For everything that happened there and…

Anyway… I'm sorry for everything.

We have spoiled you rotten, Viktor.

You need a good spanking.

You spoiled me, and I'm the one to be spanked.

It's not fair.

You don't punish Gilbert for his problems.

Gilbert is long dead.

Seriously, you screwed up.

I was trying to calculate Markov decision process

through Bellman's equations.

Nonsense!

What about the transition probabilities?

It's a zero-sum game, considering Nash equilibrium and all that.

I was also thinking about the heat transport equation.

It won't work, either.

In this case humans present not like heat

but like liquid or maybe wave.

He should have looked into hydrodynamics and the Navier-Stokes equation.

I'll show him what a clogging is.

Ira!

-Do you understand? -Yes, I understand.

In any case, you should have turned to the Millennium Prize Problems

or Poisson's relations, which also is far from simple.

The principles of optimal management a chase

are described in Pontriagin's works.

And you built your strategy upon Pac-Man.

Also, Warcraft.

Even if it were World of Tanks.

It would be enough to defeat any online gamer,

but when you're up against a mathematician,

you need different strategies. Read.

Anna Nikolayevna… Was Pontriagin blind?

Yes. Since he was a kid.

It's impossible. God…

God has no part in it. It's mathematics.

However, St. Augustin said,

"Numbers are the universal language

given to us by the deity as confirmation of the truth."

What truth?

St. Augustin never specified it.

I think, Viktor, this is a question everyone needs to answer for themselves.

You think it was a suicide?

No signs of struggle.

Nothing on the body, either.

Strange.

No phone, no laptop, no tablet. Nothing at all.

There was no mobile phone found on the body, either.

Very strange.

What do we know about her foundation?

The foundation connects scientists from across the world

for mutual support and cooperation in various fields of biotechnology,

including creation and research of bioactive compounds

related to medicine and science…

Does it say who killed the foundation's president?

We don't know whether she was killed or something else happened.

Maybe we do.

Look.

Reports for the third quarter.

Andrey Mikhaliov.

How could you miss Fatum's mathematician?

Sorry.

So it was Fatum.

So it was a murder.

The smell is delicious.

It's the sauce. I'm making chops, too.

Listen.

Life goes on if you let it.

-Yes. -It's beautiful.

Listen, Anna Nikolayevna, in practice...

How often is the stationary condition not fulfilled for the Lagrangian,

so that you need to use Pontriagin's maximal principle?

It's not what you were going to ask.

No, it's not. Well…

I mean, yes, it's not.

Anna Nikolayevna, why don't you ask me anything?

About Ira… About anything at all.

Do you want to tell me? You can't hold it in?

No, but…

Yes.

I don't know.

A raised to the power of X?

Right?

I don't understand.

Look.

The exponential function is going up faster and faster.

You see?

Yes.

My feelings for Ira were growing exponentially.

She was my… well…

Yes, speaking in your language, she was the first you did it with.

Yes.

Sometimes it seemed that the function tended to infinity.

And if we put here a minus…

With a minus, it's…

It's a fall.

See what I mean?

I had no idea there could be a minus in front of A.

The things we were doing…

I don't mean Ira. I mean all the guys. The things we were doing…

You haven't reached negative infinity, though.

Yes. It's cold comfort, though.

No, of course I was very lucky.

Because when Ira introduced me to the guys…

Now, look.

The police theorem.

Right.

I was just like this function.

Squeezed between the other two.

I wanted to fit in and not lose Ira.

Yes. Obviously.

Obviously is the most dangerous word in mathematics.

Shit.

General Sosnovskiy, I can't take a maternity leave

until we close this case.

Dad, really.

I didn't say anything.

You were thinking too loudly.

I heard every word.

Okay.

Then you'll stay at home after that. Deal?

Deal.

I'll go rush on your bosses.

And you, junior lieutenant Sosnovskaya…

Hurry up.

My daughter can't take a maternity leave because of you.

Yes, sir.

As you were.

Vitia!

Vitia!

You know, the more upset you are,

the more tender the chops will be.

I don't understand. I didn't rat anyone out.

Ira was arrested, and them… I didn't tell anyone about them.

Not Dad, not the general.

They have disappeared. They are gone.

I mean, they pretend I don't exist.

They don't answer my calls or IMs.

Nothing at all.

When you suddenly find out that you have no friends,

do you know what it means?

What?

It means you never had them.

They called me a genius.

Vitia, am I a genius?

Of course.

Then I'll tell you this, genius to genius…

Don't be an idiot.

Yes, I did send a request.

What can you say?

What do you mean, nothing? No clues?

It's impossible. Any theories?

There should be at least something.

I see.

Yes, I understand.

Send it anyway.

Yes, everything you have.

Weird.

Can you be more specific?

Dmitriy Vedeniapin.

Mikhail Andriushchenko.

The guys who were in the foundation's report with Mikhaliov.

Let me guess. They are both dead.

-Mine had a heart attack. -Mine was hit by a car.

He was 32 and healthy.

They never found the car.

Master of sports in mountaineering.

No witnesses, no security video, nothing.

Weird.

Is it good?

Divine.

I did my best. Mom reminded me about her signature recipe.

I forgot all about it.

-What do you mean? -You know the ingredients…

Garlic, seasoning, cream, and black currant.

I forgot about the black currant.

That's not what I asked.

You said your mom…

Did you see her?

No, but… she suddenly called. So…

We had a long talk, and she told me about the recipe. So…

She asked about you.

Thank you. How nice of her.

Hasn't Dad told you?

No, he hasn't.

Mom said he called her.

It's something about your wedding and their divorce.

Actually, she said she was coming soon.

-Coming here? -Yes. And she'll explain…

Of course. Of course. Let her explain it to you.

What do you think about it?

-About what? -Well…

About cheating and betrayals.

Mathematics don't use the word betrayal.

They say the hypothesis proved wrong.

Anna Nikolayevna, I'm serious.

Me, too.

Did it ever happen to you?

What are you doing?

Drawing conclusions.

Ania…

I'm sorry.

I… I mean… I didn't know.

I mean I wasn't thinking.

No, it's okay.

Yes.

It did happen to me.

A long time ago.

I drew conclusions.

What conclusions?

Since then I've been living in a space

with the axiomatics that excludes betrayal.

Just like that?

Yes. Just like that.

-What if… -If…

I'll just leave that space.

The meat was very good, and the sauce, too. Thank you.

Any ideas?

Judging by the way you came in so quietly, the news are bad.

I came in the usual way, but the news still are bad.

Report.

The search at the foundation's office didn't bring any results.

What do you mean, no results?

No results means no results. Nothing.

Not a single piece of paper. All the fingerprints were wiped out.

Moreover, no computers, no laptops. Nothing at all.

Just like at her apartment.

Nothing.

What do you mean, nothing?

Nothing means nothing.

The foundation's president was killed.

Three employees also were killed.

Mikhaliov and Andriushchenko and Vedeniapin.

We have just found out.

We have four bodies and not a single clue.

The absence of clues is a clue in itself.

You mean…

Fatum.

Yes, Nikolay, I understand. I'll be there.

Listen, I was going to ask…

I'll ask you when I'm there, okay?

Yes, Boris Mikhaylovich.

Got it. Okay.

Anna Nikolayevna…

General Sosnovskiy asks you…

Captain Vershinin has already asked me.

What are the pills for?

Are you okay?

Perfectly.

Are you ready?

In a second.

We can't make general Sosnovskiy wait.

Or captain Vershinin.

That's right. Right, Lobachevski?

Let's go.

Yeah.

I don't understand. Give me a sec.

I'll try the phone.

Don't be silly.

It's the same internet, on the phone and the computer.

Yes, but…

It's like vodka. You can drink it from a glass or a shot, but it's still vodka.

-Hi. -Hi.

Hey.

Hi, Anna Nikolayevna. Thank you for coming. How are you doing?

Okay, since I'm here. What's going on?

-Some weird bullshit. -Right. We don't understand it.

Be more specific.

-The foundation has disappeared. -It was here this morning. I saw it.

-Okay, start from the beginning. -All right.

This morning general Sosnovskiy was supposed to meet

with the foundation's president Irina Kachalova.

I asked Dad to see her.

Ira and I were in high school together. I ran into her yesterday.

She was very scared and said someone wanted to kill her.

She asked me to arrange a meeting with Dad.

General Sosnovskiy asked me

to make inquiries about Kachalova before the meeting.

About her and the foundation. I printed out all information for him.

We were supposed to meet at 10 a.m. at my office.

She was found dead at 9:30.

I was at the scene at 10:15 and called general at once.

-Was she killed? -We don't know.

When I googled the foundation this morning, everything was fine.

I mean, the information was there. On the foundation, and Kachalova.

And now it's gone.

What's gone?

The information.

Nothing on Kachalova, nothing on the foundation.

Another three employees are also dead.

One of these three was Mikhaliov, the mathematician.

He was poisoned with the same substance that you were.

Your cup contained deadly poison.

-Fatum. -Looks like it.

Is it possible that all information on someone disappeared from the web?

It's like in that meme: you haven't eaten until you posted your meal on Instagram.

Try other search engines.

How many are there?

Around ten, and only five that are of some interest.

Two major and three smaller ones.

-It's the same or all of them. -Nothing.

So they have deleted the information.

-From the web? -No. Not from the web.

Suppose I want to find out what you had for lunch.

I didn't have lunch today.

It doesn't matter.

Look.

Mitia, what's wrong with you?

Okay, it was three months ago, and it was on a bet.

It's not about you. What matters is that the search engine found the information.

Why didn't it find the foundation and Kachalova?

Because they were deleted. Deleted from the search engines.

All of them.

It's called digital death.

Yes?

Is there a way to recover it?

Not from hot servers.

Now, cold backups are servers on magnetic tapes.

Only a small number of people have access to them.

In a place that doesn't exist.

It has all the data for the last six months.

Okay.

Anna Nikolayevna. Let's go.

I'll call you back.

Vitia, too.

Let's go.

Anna Nikolayevna, are you sure you can quickly do this…

Full-text search for non-indexed text corpus?

Yes, I'm sure.

Find out when exactly Sigarev was googling this foundation.

Okay.

Do you have SAN or NAS?

SAN on optical fiber.

Eight gigabit per channel.

He says between 9:00 and 9:15.

Great. We need to narrow down the search.

They don't index the backups.

They simple store them like pages in an archive.

Get it?

It means 5,000 times less pages to look through.

How many are there?

Sixty-four racks with 16 nodes in each.

Each node is a 4-core processor, four SATA disk or two terabytes each,

combined into two RAIDs, and two SSDs also in a RAID.

It makes four petabytes.

Done. Your foundation has come back from the dead.

What next?

The usual. Click on it and enjoy.

How many of these there are on Earth?

Not just on earth.

What do you mean?

There are some under ground, too.

Looks like your foundation was working on a poison.

What poison?

Goddamn it.

What's wrong?

Anna Nikolayevna, are you okay?

Yes, it's just… I've had this headache since morning.

-Okay, I'm calling Dad. -Don't.

-His phone is turned off. -Call an ambulance.

Stop fussing around. It's just…

They'll take you home. Kirill, help her.

But the foundation?

Anna Nikolayevna, don't worry.

You've done enough. We'll take it from there.

Okay.

Thanks.

Go ahead.

Stop.

-What? -Please stop.

-The general said… -Stop the car.

This is ridiculous.

Let's go.

She is in no danger.

But the child…

We did everything we could.

It was too late when she was brought in.

Anna, get in.

I don't know where I am going.

Then you're going my way.
