Young Sherlock (2026) s01e08 Episode Script

Daddy,
Sherlock won't play with me.
Don't worry, my love. I think I…
saw some duck eggs over there by the tree.
Hello, Beatrice. I think
I saw one of those ducklings over here.
Listen, my love.
There has been a terrible accident.
A fire at the house, so you're gonna
stay with Mrs Tilcott for a while.
- Terrible accident…
- Saw some duck eggs…
- Fire at the house…
- Duck eggs…
- Fire…
- Duck eggs…
Oh. Bad dreams again?
I… I can't remember.
- The fire.
- Mmm?
Why can't I remember?
Put your coat on or you'll catch a chill.
Hood up.
I don't need my hood up.
Ah. Happy birthday, my love.
Mother. Father.
Same thing I get every year.
Where do they come from?
We get them
from a specialist shop in Holborn.
Then why
did the postman deliver it?
Who sent it?
Every year I get sent a butterfly
for my birthday.
And the person who pays for it
is in this office.
I know you.
I know, I know you.
Why did you get rid of me?
Your mother wasn't well and I didn't think
I could look after you alone.
There was no fire,
was there?
You can stay with me tonight.
And then?
You're not happy with Mrs Tilcott?
I don't belong there. I was
never meant to be a vicar's daughter.
Look, Mother. I found its heart.
I'd rather be something in your world.
The packages will be transported
across Europe.
We need to find a place
no one would think to look.
Each package is no bigger than this.
I'm busy now, my love.
Even the devil will not think
to look there.
I saw your brother,
Mycroft today.
And you'll never guess
who he is working for.
Sir Bucephalus Hodge.
The richest man in the empire.
Mycroft says Hodge has taken charge
of a government project.
Very secretive.
You know what I smell?
Opportunity.
Hodge is up to something.
Why don't I see
if I can obtain a position in his office?
Find someone that will roll over?
My little spy.
Wonderful Bea.
- How was Oxford?
- Professor Malik is the weak link.
He's greedy and vain.
If any of Hodge's professors are going
to sell their soul, it'll be him.
I've taken the liberty
of setting up a meeting.
Well played, Bea.
Professor Malik, I look forward
to doing business with you.
And I you, sir.
He's on the hook, Bea.
Hey, son
I'm looking forwards ♪
You're aiming backwards
Of this I'm sure ♪
Have you had enough?
Are you feeling rough? ♪
Does your skull hurt?
Well, if it's war ♪
I'm waiting ♪
Right here now
I'm waiting ♪
For someone or something ♪
To take me
To take me over ♪
Days ♪
Days are forgotten ♪
Now it's all over ♪
You've simply forgotten
How to disappear ♪
Beatrice?
There you are. You look worried.
We need to get our first delivery
on the train to Paris
and now we have a house full
of unwanted guests.
Add to that,
that the princess is still out there
and she won't stop until she is stopped.
I know how dangerous she is, Bea.
Believe me, we will find her.
How?
Sherlock.
You seem to have a lot of faith
in Sherlock.
I understand why you are
so unsettled, Bea.
You really don't have to face your mother.
No, I want to.
My brave girl.
My Athena.
Now, remember what I told you.
Your mother has a vivid imagination.
Bea! You have grown into the
most striking and beautiful young woman.
Is that all you have to say?
What do you mean?
I know what you did.
- What?
- I know that you were put in the asylum
because you were a danger to me.
And that's why Father had to take me away.
I see. So, that's what he told you?
Bea, he had our mother committed
to an asylum
because he wanted
to gain control of her estate.
He told me you would say this.
It's the truth.
You can't trust a thing that man says.
That man has been nothing but kind to me.
Darling!
Bea, you have to believe us.
Please listen.
- Why?
- Because we have no reason to lie.
And because I am your brother.
Dinner at 8:00.
- You!
- Mother!
You!
- Stop it. Mother, please.
- You poisoned her against me!
- Cordelia, enough.
- Mrs Holmes. Please!
There's no need for that.
Please, sit down.
It's all right.
Well…
Now the hysterics are out the way.
Perhaps we could all sit.
Please, let us sit and eat
like civilised people.
Well, isn't it lovely
to be
together again?
Reunited.
Mycroft, please, try the caviar.
- No, thank you.
- I insist. It's from Marmara.
The taste of angels.
Really, tuck in.
I'm just wondering whether I enjoyed you
more as Hodge's assistant.
Well let me know
when you've worked that out.
I must insist, the chef's gone to
an awful lot of trouble to prepare this.
How long do you intend on keeping us here?
Until you have told me
where I can find Shou'an.
Need I remind you, Sherlock,
you were going to let her kill me.
If anyone in this room
should be feeling a tad upset,
I think it should be me.
And yet here I am,
endeavouring to be fair.
Fair?
You wanted to meet Beatrice.
Here she is.
Promise made,
promise kept.
Once I have Shou'an…
…you are free to leave.
And it… is Beatrice free to leave too,
should she wish to?
She is not a prisoner.
Behind the mosque on Ordu Caddesi.
That's where Shou'an is staying.
Well, that wasn't too arduous, was it?
Bea. Bea, listen to me.
I have never hurt you…
- Go find Shou'an.
- …not once.
Nor could I, nor would I, my love.
Look at her Bea, she's telling the truth.
Sherlock, you were barely six years old
at the time.
How can you possibly be expected
to reliably remember anything?
This is what he does. He lies and he lies
until you doubt the very thing
you know to be true.
You see, in some cases, our memories
tell us what we want to believe.
Silas.
- Son.
- Shut up.
Oh. Eloquently put.
Family squabbles, eh, James?
Mr Holmes, my family, they could
squabble with the best of them.
But this is not a squabble.
This is a Greek tragedy.
Bea, Bea.
Please let me talk to you
without your father present.
When you are not under his influence.
So that should you choose,
you could leave.
Is that what you wish for?
Beatrice?
I do not.
And there you have it.
Well, of course she is not going to say so
in front of you, is she?
I think you'll find she has
a particularly strong mind of her own.
You do this! You do this!
- You bend and you twist pe--
- Will you please stop arguing?
- Is something on your mind?
- If I might have a… a word in private?
Well, anything that can be said can be
said in front of this glorious family.
Right.
I've had contact
with Her Majesty's government.
They're coming for you, Silas.
You will spend your last days behind bars.
They want their weapon back.
- Yes, I imagine they do.
- And they are willing to pay for it.
There is, however,
a path to redemption, Mr Holmes.
We want you to persuade your father
to sell the weapon
exclusively to the British government.
Pay for it?
Handsomely.
- Mycroft.
- How handsome is handsome?
I… I think you could
name your price.
There is one, um… stipulation.
They are to be the sole buyer.
And you are to be the negotiator,
my go-between?
You expect me to betray my own family?
If you want your career back, sir, that is
precisely what we expect you to do.
- Yes.
- You complete and utter Judas.
Mycroft, you cute hoor!
Jesus, I didn't think you had it in you.
See? That's what I'm talking about.
Gumption! Ambition!
They want the weapon
within one week or no deal.
- Bea?
- We can do that.
Good. I'll need
to wire the Foreign Office.
Well, I'll have you escorted
to the telegraph office
the moment it opens in the morning.
Right.
Thank you, Father.
Do you hear that, Bea?
One of my sons still calls me father.
Maybe there's a way back for me after all.
Well, it appears
Beatrice and I have to pay a visit
to our little factory…
as a matter of urgency.
You will stay here until Shou'an is found.
Beatrice, let us prepare for our journey.
How could you?
Hope you're happy, brother dear.
Far from it.
Find her!
Bring her to me.
You didn't see it coming, did you?
Mycroft's betrayal.
Perhaps he takes after you
more than I thought.
Perhaps.
You have proved yourself quite brilliant,
my boy.
Minds like yours change the world.
You're the one
I'd really like to join me.
You truly are deluded.
Now listen. What you saw in that tunnel in
Paris will change the nature of warfare.
No one will need to send troops
into battle.
It will cut down the enemy
without a single shot being fired.
And now you're going to tell me
it'll save lives.
One demonstration, that's all it'll take.
No one will dare pick up arms again.
And the people will hail you
King Silas, the peacemaker.
Mmm. Why not?
You look at the world
and see nothing but yourself.
Oh, grow up, boy.
The world we inhabit is built,
brick by brick,
on human sadness.
And it's survival of the fittest.
But you know the most radical,
original thought of all?
We are not above nature.
Some of us are humble worker bees.
Others lead the dance.
You and I are natural born leaders.
Whether you like it or not,
you, Sherlock, are my blood.
Now this is your moment, seize it.
Be my right hand. Be my successor.
Be my heir.
Is that not why you have Beatrice?
No, Beatrice is remarkable in her own way,
but you are
an entirely different proposition.
You tell Beatrice you lied to her,
you let her leave with my mother,
and I'll consider your offer.
- Oh, you heard her, she doesn't want to.
- No, of course she doesn't want to.
But if anyone could persuade her…
Talk to her, Silas.
If you can get her to leave,
I'll stay.
I'll talk to her.
Excuse me.
Shou'an was not at the address he gave.
Yes?
Am I disturbing you?
Not at all.
I found this diverting little read
on the shelves.
Ah, Machiavelli.
Since love and fear
can hardly exist together,
if we must choose between them…
It's far safer to be feared than loved.
You admire him, don't you?
My father.
I see it in you.
Game recognises game.
I'll just look at how he lives.
I mean really.
You have to admire
the scale of the man's ambition.
And if poor old Bucephalus Hodge
hadn't perished already,
well, I reckon he would've died of envy.
Ethics don't trouble you.
Not like Sherlock.
Ethics will only slow you down.
But you know that already.
In Oxford,
you stood in front of your brothers and
you didn't give them the slightest tell.
Not even a glimmer of recognition.
It's merely
a calculation of self-interest.
Doesn't it irritate you?
What?
Being in Sherlock's shadow.
Isn't he the special one?
And you, Moriarty, his sidekick?
I'm not his sidekick.
Once we're back
from the factory…
Hey, hey, hey.
…I want Sherlock gone.
Of course you do.
You wish to rule the nest.
To everything, there is a season.
Ah!
Family,
I trust you slept well.
Shou'an was not
where you told me she would be, Shirley.
- That is a shame.
- Mmm…
Disappointing.
Did you check under the bed?
No, so you'll have to remain here
until we have checked under the bed.
Mycroft,
assure Her Majesty's government
that they will have their weapons by…
By the weekend.
Certainly.
I'm sorry, Sherlock.
Mother.
Hurry along then.
Escort him to the telegraph office
and bring him right back.
My little errand boy.
You've spoken with Beatrice?
Not until they have Shou'an.
Right. We should be off.
There's no cause to be uncivil.
Quite so, my child. Quite so.
Darling, did you see?
Bea is still in there.
We just need to get her away from Silas.
I think she'll come to her senses,
Mrs Holmes.
Long game.
Thank you.
I need to send a telegram to London.
Urgent.
Ah. You.
Thank you.
Damn it.
Do you mind sharpening this for me?
Thank you.
Turn around. Open the door.
In you pop.
There's a good chap.
Apologies for the pencil.
Come.
Princess.
You do know I'm not a princess.
Old habits, I'm afraid.
I could use your help.
Looking at their routine, I'm struggling
to find a point of weakness.
We could overpower them.
Well, they are armed,
and they have the numerical advantage.
Well, tell that to the Spartans, Sherlock.
Just need to come up with a plan.
Wait.
- Is that…
- Mycroft.
- What's he doing?
- Mmm…
Well, it appears that he's waving to you.
And if he thinks he can worm his way
back into my good books,
he's got another thing coming.
No, Mother, look.
He didn't betray us.
Yes, hello? Excuse me.
I've been on an urgent mission
for my father.
If you don't open these gates instantly,
he will have your heads on plates
by the end of the day.
And we're going back upstairs.
No?
Oh, would you look at that.
Keys, please.
Think it's best if I take that.
Sorry.
Well done, brother dear.
Thank you, brother dear.
Well, that all went rather smoothly.
Yes, it did.
Get down.
Mother.
God bless you.
Thanks for coming.
I wanted to see you again.
That and kill your father.
Oh!
Ceasefire!
- Come.
- Mother, are you all right?
A little shaken but fine!
Jesus, I feel alive.
I'm sorry that I ever doubted you.
Oh, don't worry, Mother. I would have
doubted me too, given the circumstances.
Very well played.
Likewise.
Where's your father?
He's at his factory.
Where?
We don't know
yet.
Have we found any indication
on where this factory could be?
No, not a scruple.
There must be something,
some kind of hint.
What about… What about this?
Looks like some sort of coastal map to me.
It's useless.
Doesn't even have north marked on it.
Right.
The floor.
What about it?
The tiles are worn.
By frequent footfall.
Under the wall.
And why would there be worn tiles
on the floor by the wall?
There wouldn't.
Unless…
- Oh.
- Hmm…
Hmm. Just a thought.
Oh, I do love a secret passage.
All right.
Looks like an old textile store.
Why would he want to keep this secret?
Oh, my goodness.
Darling, this is the same doll that
Bea had when she was a little girl.
Do you remember?
It's opium.
He sets up a trading network
with textiles…
- And then uses them for smuggling.
- And now he uses the same routes
to smuggle the nerve agent.
Look at this. Professor Thompson…
- Here at X…
- …Malik,
Roberts,
and Enright.
Seems his work on sound waves
has been used to predict
how the nerve agent would react
to changing meteorological conditions.
Trajectories.
These are equations for trajectories.
Rockets.
They're building rockets.
Rockets to deliver the nerve agent.
Rockets to rain down death from above.
Professor Malik.
"Thanatite."
The mineral beneath my people's lands.
Right.
And this?
This is his equation
for turning it into the creeping death.
James, remember when we met?
Yes.
We create new numbers,
but the numbers, they aren't real.
They're imaginary.
Imaginary numbers created
to solve unsolvable equations.
Two solutions,
opposite or complementary.
There's always another solution
to every equation.
- Positive to mirror…
- …the negative.
- If we have the positive equation…
- …then we can come up with the negative.
And thus create a compound to neutralise
the threat of creeping death.
In theory, we can defeat Silas.
In theory, yes.
What? We have a problem?
This equation is not finished.
Sherlock, come and have a look at this.
Look.
All of these lines lead
to the heart of a circle.
Could this be blast radius?
Spread of the nerve agent.
They all emanate from one single location.
"Afshin."
His factory, perhaps?
Can you get us here?
Yes. It's about a day's ride.
Right then.
Let's go and find Beatrice.
I know a route.
It'll take us through the mountains.
I need you to tell me something.
What?
She knew, didn't she? Mrs Tilcott.
She knew exactly where I came from.
Why are you asking this now?
'Cause I want to know now.
I wanted someone I knew
who could look after you well.
This is how you found me.
Why didn't you
just send me away there and then?
Oh, it's your mother, isn't it?
That's why all these questions.
She's got under your skin.
She does that to people. I should know.
She lies. She manipulates.
I warned you about her.
It's not like you
to be unsure of yourself.
I'm not unsure of myself.
I'm unsure of you.
What on earth do you mean?
Was she really a threat to me? Mother?
Is that really why you took me away?
Are you going to tell Sherlock you
entertained his best friend last night?
Of course you won't. Why?
Because we act on our desires, Beatrice.
We act out of self-interest.
Surely you of all people understand that.
I hear how you talk to Sherlock.
I tell him what he needs to hear
to keep him onside.
Isn't that what you do to me?
Jealousy is beneath you, Bea.
Besides, the three of us together…
would that really be so bad?
We'll camp here for the night.
Now let's just say
we get your sister back,
she comes home with you,
it's all happy families,
no one tries to kill each other…
what's next for you, Sherlock?
Haven't really thought that far ahead.
Don't rightly know.
You?
I assume I'm coming home with you.
I was thinking that the British government
would pay a fair old whack
for this weapon of your father's.
I won't be a part of anything that
earns my father a single penny, James.
Not him, Sherlock. Us.
Us?
Yes.
What if we don't destroy it,
but we sell it back
to Her Majesty's Government.
Think.
It would be freedom for us, Sherlock.
We could do what we want.
They'd build great big statues of us.
No one could stand in our way.
Ah, come on. Come on. I'm only joking.
Esad,
could you see to this please?
Yes.
Right,
let's pack this up. Ship it out.
We're not just going to sell
to the British, are we?
What do you think?
The moment the deal's gone through
with the British government,
then we'll sell to the French,
the Prussians, the Russians,
the Chinese, whoever will take it.
Why stop at governments?
Go on.
Why not sell to private individuals,
to companies?
The market's endless.
Your ambition always was greater
than mine.
My wonderful Bea.
My wonderful Bea.
Perfectly wonderful.
- What is it?
- You going to Oxford.
Well, there's a good chance
you'll meet Mycroft, maybe even Sherlock.
I imagine that would be hard for you.
Of course it's up to you
if you wish to tell them, but…
if you do reveal you are their sister,
then…
…everything we've worked for together…
all of that will be placed in jeopardy.
I would never betray you, Father.
Never.
- Professor Malik.
- Mr Holmes.
Afshin.
And there he is.
Shall we go and have a gander?
That's all well and good, James,
but how do we get in?
Suggestions in a hat, if you please.
Wait.
The map in Silas's study.
The outline of these mountains.
They match.
I thought you said that map was useless.
It didn't even have north marked on it.
- Oh, it's not a map.
- It's a cross-sectional plan.
Those weren't roads,
they were tunnels.
And those tunnels are beneath our feet.
There's a second entrance.
- Impressive.
- Thank you.
There's Malik.
I'm going after him.
- Wait, wait.
- I'll go with them.
Take care.
Please.
In my village, when someone is murdered,
we believe their souls are trapped
in liànyù.
- An abyss.
- I am a humble scientist.
I seek truth.
Until their deaths are avenged
when they shall be set free.
No.
And so I set my parents free.
We bury this place.
Hello, Beatrice.
Of course you found me.
You are a Holmes after all.
I always wondered
whether you'd take after me.
Given the fact I am your elder, I think
you'll find it's you taking after me.
Bea.
Just listen. Listen to me, darling.
I… I-I don't know where to begin.
All the time that I was locked
in the asylum,
all those years, the one thing that
kept me going was my memories with you.
D-Do you remember the magpie?
The magpie wi-with the broken wing?
That we found in the forest.
You wanted to save it.
And so, we put it in a box
in the potting shed,
and we would visit it every day
and feed it.
Until one day we went, and…
…it had flown away.
It had survived.
And here you are…
You survived.
You have survived.
I remember.
You do?
I remember the magpie. I…
You'll look nice.
I believe you.
I believe you.
Oh, my love.
Thank you.
Will you come with us?
Please, darling, will you leave with us?
I will,
but there's something I need to do first.
- Lead the way.
- We'll follow you.
This will do.
This is enough to bring down the mountain.
James, what are you doing?
I'll be right with you.
- Father.
- Yes, Beatrice?
- Look what I found.
- Beatrice.
Seems you've picked up some strays.
Sherlock.
Finding this place.
Your greatest trick.
What are you doing?
I heard him, Sherlock. In the garden.
Be my right hand.
Be my successor. Be my heir.
He promised me the same thing.
Beatrice, no.
I gave you everything.
I don't want it, Beatrice, all right?
I don't want to be his heir.
Beatrice.
I'd never betray you.
Light it up.
James, now, move!
Are you all right?
Where did he go?
Where is he?
- Where is he?
- We need to leave. Now.
This way.
Sherlock!
Hyah!
Hyah!
Must I really come and find you?
It's all right.
She's here for the same reason you are.
Is there anything you need to say?
No.
Sherlock, are you gonna stand there
and watch them shoot a defenceless man?
Is that who you are? Hmm?
Sherlock.
Not in cold blood.
You made a promise.
He answers for his crimes,
and he faces justice.
You don't get to decide that,
Sherlock. Get out the way.
I'm not moving, Beatrice.
If I have no compunction
shooting my own father,
you think I won't shoot you too?
I'm not moving.
What are you doing?
No, no, no, stop this! Get off me!
Stop it! Let go of me! Let go!
I always knew you loved me, my boy.
No, don't. Don't.
All that remains.
At what point do you think
he took the wrong turn?
Went down the mistaken path?
Well, as far as he saw it, he didn't.
Everything was intentional.
Everything by design.
He was… …unrepentant.
Lived by a different code.
- You're defending him?
- I'm not defending him, Mycroft.
I'm trying to understand him.
Trying to understand his…
criminal mind.
Sherlock?
It's like a honeycomb.
Apis mellifera.
The humble honeybee.
Please, stop.
He wanted me to have this. Why?
We are not above nature.
We are not above nature.
- He said those words to me.
- Sherlock?
He was leaving me a trail.
Enough, Sherlock. I-I really must insist.
Everything by design.
Not a word out of place.
Survival of the fittest.
The most radical, original thought
of them all. We are not above nature.
Sherlock! Enough. You're making no sense.
Original.
Darwin.
We are not above nature.
Everything by design.
Put it back.
Why?
Please.
Close the book, Sherlock.
It-It's over.
Thank you, brother dear.
You know, I've never
been particularly fond of royalty.
But…
I must admit,
you're my favourite princess.
Thank you, Sherlock Holmes.
I do hope you find a way to put
that beautiful mind of yours to good use.
Perfect match.
Hello, you.
Hello.
- You look tired.
- Hmm.
I didn't get much sleep last night.
Oh, it's my fault, is it?
Not complaining.
I have something to show you.
Intrigued.
I think we'd work well together.
You and me.
Were you followed?
No, I was careful.
Okay. Sherlock's here.
Don't turn around.
Out the back.
- See you tonight.
- Yes.
Thought I'd find you here.
Hmm, you thought right.
Needed to get away from the family.
Oh. They'll fuck you up.
- Especially yours.
- Especially mine.
- Uh, two whiskies, please.
- Very good, sir.
Do you regret losing your scholarship
at Oxford?
Do I regret meeting you,
this porter with the wastepaper basket?
Scout.
Never made it to the gilded heights
of a porter.
- You know, had you not let me astray…
- I led you astray?
…I would've undoubtedly graduated
top of my class.
Undoubtedly.
And gone on to have a stellar career
in government.
Unstoppable, I would have said.
Probably would've ended up
as Foreign Secretary.
Don't put the blinkers
on your ambition, James.
I would have said Prime Minister
at the very least.
Yes, I could be the master puppeteer,
pulling all the strings, huh?
Well, if you insist.
No.
I have no regrets.
In fact…
I feel as though I should thank you,
Sherlock Holmes,
for saving me
from a life of sheer boredom.
Well, to that I would say
you are most welcome.
What?
I know you have it, James.
Don't be going all cryptic on me now.
The remainder to Malik's equation.
I know you have it.
You're right.
Of course you're right.
Yes, you know I took it,
and you know why I took it.
I took it for us.
If that weapon ever rises
out of the ashes,
then we have the means
to defeat it together.
You and I.
What? You don't believe me?
Ah, Sherlock. After everything
that we have been through, surely by now…
you know me.
What's that?
Nothing.
Nothing?
It's nothing.
