When you arrived in Marlow, you and Tristram pretended you didn't know each other, like a couple I met earlier today.

Although, unlike them, you pretended you hated each other.

(yelling indistinctly, audio distorted) (screams) JUDITH: But what you didn't know was that Tristram had an on-off girlfriend he couldn't keep away from.

The plan had always been for you and Tristram to get together after a decent amount of time had passed.

And if, eventually, you married your dead fiancé's son, well, tongues might wag, but where's the crime?

But if he married Sarah, you'd get nothing.

You acted fast.

You used the rat poison Tristram had stolen when, I imagine, the two of you were considering poison as your method of dispatch.

And you murdered Sarah to remind Tristram that his future was with you and no one else.

That's how I knew he'd come for you when he was released on bail.

Sarah was an innocent.

You killed her because you were jealous.

Tristram wouldn't forgive that.

I wasn't jealous.

What Sarah had with him was better than what you had with him.

How dare you.

Which is why he always went back to her.

(choking back tears) He betrayed me.

You, who'd risked so much.

You, who trusted him.

You, who even killed for him.

I didn't kill for him, I killed for me!

Which is what we in the trade call a confession.

No one will believe you.

It's your word against mine.

That isn't entirely true.

Is it, Tanika?

JENNY (on recording): I didn't kill for him, I killed for me.

Hello, Jenny.

No, I saw you leave in your car.

No, we took a leaf out of your book and decided to stage an argument.

Jenny could've been killed!

BECKS: You have gone too far this time.

Which started a chain of events that allowed me to be here.

You saw my car leave, but it wasn't me driving.

And that is how I'm still here, when you thought it was just you and Judith.

You tricked me?

No.

You tricked Sir Peter, I worked out how, and she is going to arrest you.

(handcuffs click) (car approaching) (car doors open) (Brendan sniffs) BRENDAN: You used me, didn't you?

(car door closes) TANIKA: No idea what you're talking about.

VICKY: I hear congratulations are in order.

Boss, you should know... That it was all thanks to Brendan here.

What?

It was his idea to arrest Tristram to create the perfect conditions for Jenny to make her confession.

Oh.

Without Brendan, our double killer would still be out there.

Isn't that right, Detective Sergeant?

Um... Yeah, yeah, that's right, ma'am.

Um, it was really a joint effort.

Oh, very good.

Yeah.

Very good.

Well done, team-- let's get this processed.

(car approaches, engine stops) (laughing): We got her?

We did.

(laughing): Amazing!

No, seriously, amazing!

And, um, I'm sorry about what I said.

Did I go too far?

Mm-mm.

(laughing): Did I?

(chuckles) I mean, I didn't mean any of it.

I mean, we're your friends, you know?

We get you, Judith.

Even if sometimes we like to tease you... (chuckles) ...it's because we love you.

Yeah.

And this is the bit where you say the same thing back to me, yeah.

Yeah, well, I... TANIKA: Sorry.

Uh, where's Becks?

And where's my car?

(phone vibrates, ringtone plays) (ringtone stops) COLIN: Where are you?

I'm sorry, we were catching a killer.

Don't worry, I'm still here to pick up Sam.

But I missed our date!

It's all right.

You can tell me all about it when you get home.

BECKS: Love you.

(chuckles) Is that, is that my mum?

Mum, where did you get this?

Believe it or not, I stole it.

(chuckles): You've stolen a police car?

From the police?

Let's get you home.

(engine starts) Can we put the lights on?

And, and the siren?

I think that's exactly what we should do.

(chuckles) (siren blaring, Sam laughing) That's sick!

See ya later!

(laughing) See ya!

BOY: Sam!

(boys laughing) BOY 2: Sam, what are you doing?!

(laughing, exclaiming) Oh, man, that's sick.

ROSANNA: It's still so hard to believe.

What a mess.

Thank you.

For catching father's killer.

It's the least he deserved.

TANIKA: Miss Bailey.

Under U.K. law, no one's allowed to benefit from a crime they commit.

Your brother won't inherit a penny.

Your father's entire estate, his house and money, will go to his next closest living relative.

You.

I'll make sure good comes of this.

(door closes) Look, I understand the why of it, but not the how.

How did Jenny manage to push that massive cabinet onto Sir Peter without being in the room?

Oh, it was Lady Bailey who revealed the truth to me.

You see, I'd worked out there was something wrong with her testimony, but it was only when I saw sunlight through a carafe that I realized.

When I inspected the jar of magnesium tape... ...it was in a sunbeam.

It was morning, and the sun was shining through the window.

But if the sun was shining through the window in the morning, how could it still be shining through the window in the afternoon?

So, if what Lady Bailey saw wasn't sunlight, what was it?

And that's when I remembered the magnesium tape.

When you light it, it burns white-hot.

And it's strong.

This is what happened.

Jenny got the study ready before the party.

She arranged all the equipment from the cabinet onto the floor in front of it and tied magnesium tape from the top of the cabinet to the hook on the wall.

That way, when she pushed it forward, it would lean over, but not fall.

You see, all along we've known that it was impossible for someone to get out of that room once it was locked, but there was one way in and out, even if it was only inches wide.

Hold on.

Here you go.

Lady Bailey told us that Sir Peter's bedroom was directly above his study.

LADY BAILEY (voiceover): Well, I knew no one would be on that side of the house.

There's only Peter's study and his bedroom above it.

They shared the same flue.

SUZIE: All she had to do was run the magnesium tape down the flue and connect it to the tape already attached to the hook.

Except, when she put the jar back, it wasn't quite in the right place, so it didn't smash when the cabinet fell.

Which Judith noticed-- of course she did.

Jenny had created a fuse that ran from the bedroom, down the flue, across the room, to the cabinet.

May I?

You may.

JUDITH: Rosanna thought Jenny was lighting a cigarette.

(lighter clicks) (flame hissing) But she was doing much more than that.

This was the bright light Lady Bailey saw.

Not sunlight-- magnesium tape.

♪ ♪ (flame hissing) ♪ ♪ JUDITH: Then, when everyone heard the racket of the cabinet crashing... (creaking) ...they presumed that was the moment that Sir Peter died, when, in reality, he'd been killed a few moments before.

And the will?

How does that fit into this?

That was a piece of improvisation from Jenny.

Her whole plan was based on her having no motive, but Sir Peter made up a new will.

She must have been in such a panic when she heard about it.

What was in it?

Would she now inherit?

As soon as she saw it, she hid it.

SUZIE: And she was right to.

It left everything to her, giving her a red-hot motive.

But it also named Tristram as the killer, her partner-in-crime.

Mm, she had to protect him.

(phone vibrating) JUDITH (voiceover: Until she learned that Tristram had an old girlfriend who was still on the scene.

Do you know who that is?

No.

JUDITH: Which is why she decided she'd make sure that it was now found.

Pointing the finger at Tristram.

ADAM: Miss Page asked me to work on the lawn.

JUDITH (voiceover): She needed to remind him of the power she had over him.

BECKS: Oh, this is the signature.

(door opens and closes) BECKS: How did it go?

Did we do it?

Did we get her?

SUZIE: Oh, Becks, it all went wrong.

She, she got away.

What?

Suzie!

(laughing) (exclaims) It went exactly as Judith said!

Yes!

Yes!

We got her!

(both laughing) SUZIE: I know you said you didn't want it, but you never know.

Oh, no, wait, wait, wait!

ZETA: Mm?

One last thing.

What, Mum?

I ordered it last night.

You know, just in case.

Here you go.

Now you're all set to cook!

Oh, thanks.

Oh, I'm so proud of you.

(sighs) Mum, I have to get there today.

Yeah, you go-- I know.

You go.

Have the best time.

No, I got it.

(car door opens) I love you.

Love you, too.

You'll be fine.

You and me, we're always fine.

Bye!

Be careful!

(exhales) (softly): Stay safe.

We thought you might want some company.

Seeing as you're our friend and... ...we love you.

Well, you, you'd better come in, then!

Yum, yum.

(chuckles) JUDITH: We got margaritas.

SUZIE (laughing): Oh, that's my favorite, thank you!

JUDITH: Did you know they're named after Queen Margherita of Savoy?

I looked it up.

She visited Naples in 1889... SUZIE: All that matters is that it tastes delicious!

JUDITH: And the colors represent the colors on the Italian flag.

SUZIE Oh, Judith!

BECKS: Judith!
