By the way, today's our first anniversary with Katia.

A golden jubilee.

Plus a couple years when I didn't dare approach her.

You are so shy.

Kolia arrested Ania as soon as he first saw her,

so that she didn't escape.

How did you two meet?

It was fate.

Luck.

Well, not exactly luck.

I didn't have makeup on me, up to my elbows in blood and guts,

performing a postmortem, sorry for spoiling your appetite.

She also performed a thoracotomy on me and stole my heart,

my big lonely heart, like a lamb's.

Article 158, Part 4.

Why 4?

The heart is big, so it's large scale.

No, it's up to eight years.

I won't take anything less than life sentences.

We won't take it.

You're lost, Mitia.

What does mathematics say about love?

Mathematics…

-Mathematics has seen bigger dramas.

Like what?

Like two parallel lines that will never meet.

Just a second.

The tangent line and the diagram cross only once.

What? I read it online.

It's not true.

The tangents aren't directly connected to the number of contingencies.

Those who wrote this online didn't pay enough attention at school.

There is also this axiom.

The asymptote…

and the function graph…

gravitate towards each other but will never be together.

Sounds like poetry.

Mathematicians who lack imagination to become big mathematicians

become poets out of desperation.

Well, to poetry.

Great.

And mathematics. How can we do without it?

THE MOP 2

Good morning, Anna Nikolayevna.

Take a seat.

Please meet Irina Markova, vice president of the Gradient Bank,

and Yevgeniy Pereslavtsev, the security head.

The bank you had hacked in.

Nice to meet you.

Who in the 21 century still uses 64-bit encrypting?

It saved my life, though.

We knew about this problem.

We've been ready for 128 bit for a while, but it's a lot of work.

We had to stop all servers, update the software, restart them.

Then I helped you.

Is that what you call it?

It's already done.

Do you know that the money you had transferred…

It came back.

I didn't know that.

The very next day.

Banking day, I mean.

The clients never found out.

That's very strange.

And illogical. Maybe it's a mistake.

No. I don't think it's a mistake.

Why would Fatum want it?

I don't know.

Why are you asking me?

Unlike us, you talked to him.

So?

What of it?

I assure you this wasn't a mistake.

This man doesn't care about the humankind in general

and any human in particular.

He is obviously up to something, but I don't know what it is yet.

He talks a lot, he talks pretty,

saying some nonsense about fate.

He'd probably say something like "It's easier to open an open door".

What does it mean?

I don't know. I'm not Fatum.

What is her name?

-How do you know? -I'm a cop.

You're trying on the third T-shirt in three minutes.

-So what is it? -Well…Yeva.

Do you need money?

Could you?

Depends on how much you need.

Well, the café, the movies, maybe something else.

The usual.

Here. Will this be enough?

Yes. Thank you.

Do I look okay?

Yes.

Here.

Something for you to have fun.

Don't miss me too much.

Hi.

Hi.

Where are you going? Stop, stop, stop.

Come here.

Come on, come on.

Nikolay.

Do you know that people pass to each other

278 kinds of bacteria during a kiss?

Of course I know.

Fortunately, 95% of them present no danger.

Right. The general must have really gotten on your nerves.

No.

It was actually Fatum.

Is he back?

The general said the money I had transferred back then

were returned to the bank. Every penny of it.

I don't understand.

Neither do I.

If it weren't Fatum,

I'd think it was a mistake or a glitch in the system.

Ania, why do you think your Fatum cannot be mistaken?

He isn't mine.

And he hasn't made any mistakes yet.

Leaving me alive was a big mistake, though.

I'm grateful to him for making it.

I'll tell him when I catch him. And I will.

Yes.

Where is Vitia.

Vitia is on a date.

Really?

Yet.

While he is on a date, I'll gladly share with you a couple dozen…

of bacteria, cultural and otherwise.

One. Two.

It's 278, not a couple dozens.

Never mind.

I do mind. You need to be exact with numbers.

I thought you'd never do it.

I…

Shall we have another cocktail? I'll have a virgin mojito.

You got it.

DAD'S MONEY = 3500

MOJITOS = 880

MOVIE TICKETS = 1300 ICE CREAMS = 600

BALANCE = 280

Here.

-Hi. -Hi.

A virgin mojito and a glass of water, please.

It bounced off.

What?

You probably don't have enough money on your account.

It can't be.

WITHDRAWAL 101 RUBLES

You're late.

Are you tired?

And drunk.

Did you have a cause?

I was trying to open

an open door.

Did it work?

Let's go.

Come on.

Let's go.

Hi.

Hi.

-Do you take credit cards? -Yes.

Another hot dog, please.

You can pay now.

Okay.

Thanks.

Another one, please.

-Did you like it? -He did.

You can pay now.

Okay.

Yeah.

Good things come in threes.

-More? -Yes.

Anna Nikolayevna. Can you come?

Thanks.

Here.

Why did you give him this crap?

-Why not? -It's bad for him.

-I didn't know. -Now you do.

Anna Nikolayevna, do you have an account at the Gradient Bank?

Yes.

-Do you have your credit card on you? -Maybe.

Can you check the balance? There is an ATM.

I actually have an app on my phone.

Just make sure you remember the number.

Vitia, I'm good with numbers.

Well? What is it for?

Buy a hot dog, please.

I'm not paying for this horror with my own money.

Well, a cup of coffee, then. It doesn't matter.

You don't even have to drink it. Just buy it.

A hot dog, please.

Because dogs don't drink coffee.

You can pay now.

Now check the balance again.

Why?

Come on, do it.

What did it cost?

Interesting.

I've already fed him four,

and each was one ruble more than it should be.

I said no calls.

It's the Mop. Miss Shvabrina, I mean.

Good morning, Anna Nikolayevna.

Boris Mikhaylovich,

can you be at the Gradient Bank's HQ in half an hour?

I think I know how to open the open door now.

It appears people are not that wicked once you catch up on your sleep.

You obviously haven't.

But it isn't just that.

Can you believe it? The money Fatum had stolen from the bank came back.

-What? -Yes, I know.

I don't understand.

Neither do I.

Does Ania know?

She's the one who told me.

And General Sosnovskiy told her,

so they both know and neither of them understands.

Maybe something went wrong for this Fatum, and that's why the money was returned.

He didn't steal it just to give it back.

Boris Mikhaylovich, we are here, as you asked.

I just wish we knew why.

I need access to the repository.

What?

It's impossible.

Do it. Now.

-What is this… -Repository?

It's where a bank's source code is being stored.

Instructions. The laws the bank lives by.

Its constitution.

Except that the bank does abide this constitution.

Thank you.

What do you need it for?

Your bank is robbing people.

We don't violate any banking rules.

Our mortgage rate is…

Anna Nikolayevna, is it about mortgage?

Of course not. Though I suppose it's robbery, too.

What do you mean, then? What do you expect to find there?

The code that is stealing money.

There are hundreds of micro services, tens of thousands of files,

millions of code lines.

Excuse me, what are you going to do?

What programming language do you use?

There are many.

Mostly Java, C++…

Vitia, we need to build

an abstract syntactic tree after Chomsky hierarchy

and apply the Levenshtein distance…

-To find the variables we need? -Of course.

Please don't disturb us.

Yes, we know what to look for. One ruble.

Is Chomsky that American anarchist?

Yes. He also created that universal grammar system for programming languages.

Looks like this micro service is the problem.

What does TransactionProxy do?

It's the basic server.

The one where the transactions are being made.

There were no changes in it for five years.

Judging by the logs, it was changed, and very recently. Here.

The code was changed.

And what happened?

It's like with the Constitution.

Someone changes it, and you wake up in a new country,

even if you don't notice it.

So we didn't notice anything.

I don't understand. The money was returned.

That's the point. The theft was just a trick, a distraction.

A distraction from what?

When I hacked your bank,

someone took advantage of it and changed the basic server.

It was virtually impossible to discover.

So you installed it by upgrading your servers.

And we woke up in another country.

Yes.

You didn't change the code, am I right?

I need the bank transactions after the hacking. All of them.

But there are hundreds of thousands.

Yes.

And I need them printed out.

I'll need a room, colored markers,

paper, and coffee.

A lot of coffee.

-Do you bake sweet potatoes in foil? -What?

Do you bake sweet potatoes in foil or just on a tray?

On a tray.

Found it. Here he is.

Katia, call the general. Let him look him up on their database.

Do you add basil?

I do.

Good girl.

But I still recommend foil.

Mitia, I'm going to kill him.

And you should.

-Whom? -This Fatum.

You need to catch him first.

Mitia, there should be some logic.

Of course there should be. It's just that we don't understand it.

Katia had been weeping all night yesterday.

-Why? -She wanted sweet potatoes.

-By the way, where is Katia? -At the store.

That's her.

Yes, darling.

Just stay out of it. We're coming.

-How are you? -Okay.

He was here, and then he disappeared into thin air.

Did you see you?

Yes. He asked how I baked sweet potatoes.

It was so unexpected.

I was taken aback and didn't notice where he'd gone.

How unfortunate.

No, it's fortunate, because no one knows what he might have done to Katia.

Right. We need to look through the security video.

If he paid with a credit card, we'll find out who he is.

And if not, we'll find out what he likes for dinner.

Katia, where are you going?

To get the eggs.

I'm ready to explain what happened when I hacked into your bank.

A code was installed into your system

which transfers one ruble from each transaction

to another unsuspecting client.

Holy Molly!

Exactly. These clients are like piggy banks.

When a certain sum accumulates on their account.

it gets transferred to other clients.

If I were a poet, I'd probably say something about a riverhead

where many springs come together to form a river,

and then this financial river flows to several cryptocurrency exchanges,

where the money turn into bitcoin.

Goddamn it.

Since I'm no poet but a mathematician, I'll put it simply.

This scheme has robbed your clients of one million.

We'll have to compensate them.

Wait, we can trace…

The thing is, they change these human piggy banks all the time.

Since the code is installed on the lowest level,

no one notices anything.

You spend 100 rubles,

you get a notification that you were charged 100 rubles,

when in fact you were charged 101 rubles.

And no one is any wiser.

After the money is converted into bitcoins, it's untraceable.

It's millions in losses.

In fact, Vitia was affected worse than anyone.

His date got canceled because of all this.

It's okay. We have rescheduled or tomorrow.

I not for him, I don't know when we'd have noticed.

Listen. We need to destroy this code ASAP.

No.

No way.

If we destroy the virus, Fatum will know.

So? Shall we let him keep robbing people

and keep paying for it?

Yes. Something like that.

At least no one will find out that your bank shouldn't be trusted.

Wouldn't it be a bigger disaster?

-Anna Nikolayevna. -Yes?

Can we trace them? These money springs.

I don't know. I need to think.

Not here. At home.

My driver will take you home, of course.

But come back tomorrow at 9.

Thank you. Let's go.

People buy weird things at stores.

When was the last time you were to a store?

-The day before yesterday. -Here it is.

A baguette.

Sweet potatoes. You aren't alone.

Sour cream.

Some shit.

Well…

Cash.

What is he doing?

He's telling me I should bake sweet potatoes in foil.

So he figured you out?

He probably recognized her.

They were following Ania, so they must have seen us all.

Right.

At least he didn't kill me.

Of course.

The Edmonds-Karp algorithm.

Did you say something, Anna Nikolayevna?

She said she has a solution.

Hi, Ania.

Hi, Vitia.

Hi.

Vitia, will you explain what's going on?

Dad, you won't understand.

Try me.

Or I'll put you in the corner and take away Anna Nikolayevna's markers.

Okay, can I have some quiet?

You won't understand.

Make me understand.

I think Anna Nikolayevna and I have figured out Fatum's scheme.

So what is it?

I'm not sure but I think Anna Nikolayevna will understand.

Vitia.

Have you changed your mind?

I won't eat until we catch Fatum.

Anything or just sweet potatoes?

Very funny.

I was so scared when I realized he was following us.

We'll find him. I promise.

-Really? -Really.

Now start cutting this crap because I'm starving.

Or do it later.

Unfortunately, we can't trace the end benefactor.

Sounds hopeful. Why?

Because since a certain moment here

all money goes into bitcoin.

And you can't trace bitcoin?

That's what bitcoin was invented for.

And?

But I have found out something that happens before the bitcoin.

Someone is pinching off pieces of this pie.

Look. Imagine that all bank transactions are a huge transport network.

An oriented graph

where transactions are cars moving from one junction to another.

There are cars that abide the law and follow the rules,

and there are entitled persons that drive however they want.

Was Liosha pulling his rank again?

Yes, but it's not the point.

I was able to separate offenders from law-abiding cars.

And among these offenders I found another money flow

that is going the wrong way.

Does he have any distinctive features?

He even have a name and a surname.

Vladimir Berezin.

And an address.

Vershinin.

Get the team ready.

What's going on?

Who are you?

Sveta, the niece.

Vladimir Berezin?

That's him.

Can't he talk?

He can't. For the three months after his stroke.

What happened?

-Hi. -Hi.

I'm Svetlana Permikina, his niece.

I'm the only family he has. I'm taking care of him.

Does he have the Gradient Bank's credit card?

He does. I have it.

His pension goes there and his disability benefits.

-May I? -Yes, please.

Thank you.

Tell me, what is he accused of?

-Bank robbery. -Robbery?

But how would he? You see how he is.

Or rather, robbing the bank robbers.

They never patched up the firewall, the idiots.

Two credit cards were issued for Vladimir Berezin.

One of them – two months ago.

It was issued by Svetlana Permikina,

while she was still working at the Gradient.

What will happen to my uncle?

Is he really your uncle?

Yes. He is the only family I have.

He…

He raised me after my parents' death.

You'll say he didn't do a very good job, since I'm here.

But it isn't his fault. He didn't know anything. It was all me.

Don't worry, your uncle is fine.

He's in the hospital, well taken care of.

Technically, he is still a suspect.

Thank you.

Your Vershinin is good at it.

He knows how to win their trust.

Winning trust is what he does.

That's how we met. At an interrogation.

Remember the TV show when we were little?

"If each of 100,000 viewers gives one ruble…"

Yes, I remember. "It will be crazy money".

Right.

It was my dream.

Not crazy money but any money.

My uncle had a job, but it was barely enough for the food.

Well, actually…

Uncle gave me my first computer as a birthday gift.

A 386. He had been saving for it for six months.

I had one like it. I bought it or myself, though.

I found books on programming in the library.

Basic, Pascal, Fortran. I fell in love.

I reinvented the quick sorting algorithm when I was in the 8th form,

programmed a model of the solar system in the 10th form.

I deduced the formula for solving cubic equations in the 8th form

and proved the harmonic series convergence theorem in the 10th.

Who cares about harmonics in the 10th form?

There are other hormones at play.

Euler found it interesting, and so do I. That's what was important.

I didn't think about hormones back then.

I wasn't interested in boy back then.

I never was very lucky with boys or men.

Here you are supposed to say you got lucky with Vershinin.

But I'm not going to.

You probably don't want to hear all this.

You need to close the case.

We need Fatum.

Yes, we need to close the case.

I'd like to understand…

I found a job at the bank, in support.

What happened then?

That's the point. Nothing was happening.

Absolutely nothing, or years and years.

Uncle was getting sicker, I worked.

I wanted to find another job, but I had no degree and…

Never mind.

Then a man showed up who asked "What can I do for you?"

You know, that's exactly how it happened.

But he showed up and said

"Let's fuck".

And?

And we went and fucked at a shabby hotel.

You know, it helped.

Fatum?

Not the words he'd use?

No, no. Besides, he'd never do it at a shabby hotel.

I don't think.

Then, when we started seeing each other…

at shabby hotels.

What was his name?

Rodion.

Last name?

-I don't know. -Was it his idea?

I'd never have brought myself to do it.

So what happened?

I came up with this Trojan a while ago, but I wasn't going to use it.

It's…

You know, like children when they fantasize

how they'll grow up and…

It's a brilliant idea, actually.

And the realization.

She is a very good programmer.

I don't care. I need Fatum.

So you told this Rodion all about it.

By the way, how did you contact him? Do you have his number?

No. He always called from different numbers.

Or, more often than not, he'd just show up.

Sometimes I wouldn't see him for months.

Did you tell him about the virus?

-What did he say? -At first, nothing.

It seemed as I he didn't understand.

In a couple days, he came back and said,

"Let's do it".

And?

He talked me into it.

She didn't trust this Rodion any longer.

Why?

It'll take a while. Take a seat.

What happened next?

Otherwise, she wouldn't program her…

What was meant to happen.

…personal money stream.

I saw him with another chick.

By accident.

Younger than me. Legs, tits.

I don't need to tell you. You're a man. You know.

What did you do?

What would you do?

How much did she steal from Fatum?

I gave Rodion the flash drive with the Trojan.

By that time…

A couple millions.

…I quit the bank. Uncle was very sick.

But you issued a second credit card for him and…

Yes. I didn't trust Rodion by then. I knew all he wanted was the virus.

I tricked him.

Lucky on her that Fatum never found out.

He'd have killed her.

It's a wonder he didn't kill her after getting the virus.

He probably wanted to check how it worked.

Do you have a picture of this Rodion?

He… wouldn't let me.

Can you describe him?

A man.

A manly man. Big.

Is that him?

Dixi.

What?

As was to be proved.

It doesn't lead us to Fatum.

Did Rodion leave you

any contacts for an emergency?

Although…

He said if Uncle got worse, I should take him to Hospital No. 2.

-Why there? -I don't know.

He told me to find…

Arnold Giskin, I believe.

He'd help him, and Rodion would know about it.

This is so exhausting.

Do you think it will work?

I hope so.

Tomorrow we'll transfer her uncle to Hospital No.2

and register the call from Permikina's apartment.

Then she'll go to this Giskin,

if he really is a surgeon at that hospital.

And then we'll wait.

Have I ever told you

how lucky I was to get you?

And I to get you.

You never said to me "Let's fuck".

Okay.

We can fix it.

Come here.

-Careful. The laptop. -I am careful.

Oh God.

Oh my!It's not funny.

-Freeze! -Nikolay. Please! God.

On the ground! Hands on your head!

-Nikolay, wait. Let's talk. -I said lie down!

What are you doing, Nikolay?

Why did I say that?

You idiot! And so am I.

I don't remember if I took my pills today.

God, what if someone sees us?

Okay, the distribution of the probability of pregnancy in relation to the cycle

is subjected to G-distribution.

Or at least it should be.

You can't calculate the probability in an elementary function.

To hell with elementary functions.

No. God, what if I get knocked up?

This is so uncomfortable.

Wait.

Wait! I'm somewhere between the 22nd and 25th days.

It's 4.7%.

God, don't stop. Yes.

If it's under 5%, then Fisher…

The statistical significance according to Fisher…

Yes!

Yes!

Don't worry. We'll hear every word.

It's a hidden mike. This is a hidden earphone.

-Excuse me, are you Dr. Giskin? -As you can see.

-Arnold? -Yes.

I…

Rodion said I could turn to you if something happens to my uncle.

What's wrong with him?

A stroke. He is in Unit 4.

But Rodion said…

I get it. Wait a minute.

So far, so good.

He's coming back.

Here.

Your uncle will be fine. Don't worry.

Hello?

Come to the Jasmine café on Rechnaya in an hour.

I…

I missed you.

I missed you, too.

Rodia. Rodia, wait.

We have one hour.

We'll be following you. Just come to the rendezvous and wait.

We have our men there.

Let's test the communications.

Say something.

-What? -Test.

Test, test.

Great. Do you hear me?

-Yes, I hear you. -Okay.

Everything's fine.

Stop at the crossing.

Go.

Don't be scared.

The workers to your right are our men.

Don't look back.

I see her.

You are doing great.

You're almost done.

A biker is approaching the subject.

I can't see the face.

I am watching the biker.

Coast is clear.

You look great, Anna Nikolayevna.

I can see you aren't happy to see me.

I see a quadcopter approaching the subject.

I was worried if Vershinin will make it in time with the antidote.

I knew he would, though.

I always know what is going to happen.

You don't believe me?

The quad might have weapon on board.

Suddenly you have a blackout at home and go down to have a cup of coffee.

Nothing serious, a routine problem.

It will be fixed in the next five minutes.

I can't destroy it. The subject is in the line of fire.

You see, I don't just know the future: I control it.

On the ground!

Now Vershinin will call you and say that Permikina was shot by a quadcopter.

In the square where she was supposed to meet Rodion.

Which isn't his real name, by the way.
