Right.
March and April Beaumanor log sheets...
and the intercepts from March 28th...
April 3rd, April 9th, 1 5th, 1 6th, 1 7th...
and Kestrel settings-- last one first.
Might tell us why Claire disappeared.
Right. April 1 7, rotor order.
3-5-4.
R-X-O.
- Plug board settings. - A-O-E-M.
The current passes from the keyboard...
to the lamps by way of the rotors and the plugs.
And every time you press a key, it changes the path of the current.
Press the same key ten times, it comes out ten different ways on the lamp board.
You never know which letters will light up. Simply brilliant.
Message key X-A-T.
- Ready? - Ready.
- "Y." - "K."
- "E." - "A."
"W."
"C."
- "U." - Zed.
"M."
"V."
- "Q." - "X."
It's not right, is it? This isn't German.
Keep going. Sometimes the operator pads out with nonsense.
Keep going.
- Um, "K." - Zed.
- "E." - "R."
- "O." - "A."
- "F." - "D."
Isn't German. Come on, genius!
I'm sorry. It's double coded, or the settings must be wrong.
It's all been for nothing.
I'm afraid I have to ask you to hurry up.
Search the barn.
This is Mr Leveret. Detective Inspector Leveret.
He wants to know what you've been up to. But first things first.
You've been here before?
And you?
Line up in the street and search the area.
Have a look at this, sir. It's down there.
- Right, sir. - There?
Drag the river.
Please talk to me! What do you want to know? I'll tell you anything you want.
Give me your hand.
Do you wanna know about Shark? Any secret. Ask me!
Come this way.
I've got something to show you. Get your notebook out.
Miss Wallace first.
I am showing the witness one ladies' coat, colour grey...
trimmed with black velvet.
Label: Hunters, Burlington Arcade.
- And the witness responded-- - Yes. It's hers.
Yes.
Next, one ladies' shoe...
black high heel.
Uh, heel snapped off.
And the witness responded--
Yes.
It's an old quarry.
They built the town with what they dug out.
That makes sense, making one hole out of another.
- How deep is it? - Sixty, seventy foot in the middle.
Christ, we'll need a submarine.
I would very much like to arrest you...
but we don't have a body.
It's a quarter to 8:00. Mr Leveret will take you back.
I believe your day is just beginning.
Chaps.
Easy, everyone. Just stopped by to wish you luck.
I'm sure you're all aware, as I am, what's at stake here.
I don't think I'm exaggerating when I say...
this could be one of the decisive nights of the war.
- So shut up, then. - A mighty battle.
Probably...
the greatest convoy battle of all time is about to start.
Three hours ago, convoys HX 229A...
229 and SC 1 22...
had entered the presumed operational area...
of the U-boat packs.
Now, in our long island history...
we have picked up the gauntlet more than a few times.
Shakespeare coming up.
"Out of this nettle, danger, may we pluck this flower, safety."
So, gentlemen, go to it.
Come and dance. Boop-boop
Come on. Come and dance.
- No, I can't. - Yes, you can. It's easy.
- No, really, you do it. - Right, left.
Left, left.
Ah! You're getting the hang of it.
C-Can someone remind me?
A-Are w-we hoping for the U-boats to find the convoys, o-o-or not?
- Not. - I am.
- Yes, well, you would, Baxter. - Y-You'd sacrifice o-o-our--
Sacrifice a convoy to get back into Shark? Of course.
How many men has Stalin had to sacrifice so far? Five million?
It's called the greater good.
Spoken, of course, by someone who doesn't happen to be in the North Atlantic at the moment.
You can only fight your own war. What do you think, Tom?
About what?
So, Claire, what were you doing?
What were you hiding?
Right.
Start at the beginning.
Kestrel settings, March.
Atlantic time is two hours behind.
It's still dark.
Here, mate, I got a lighter.
Thanks.
"Urgent."
Mary Jane Hawkins.
It is German.
Signal 7-3-6-9-K-C-S.
We're in business.
Direction finders have a fix.
Scarborough, 2-5-9 degrees.
Witt, 2-4-6, 30 degrees.
Flower down, 2-6-8 degrees.
There she is-- 37.5, 49.5.
She's shadowing convoy HX 229.
No air cover. Sitting ducks.
Grid square?
B-D-1 491.
- Convoy course? - Seventy degrees.
- Convoy speed. - Ten knots.
- From the code book, we have C-K-S-A for convoy sighted. - First message?
K-A-F-B-N-W-Zed-Jacob for position.
Q-K-D-X for course, Q-R-Zed-A for speed. That's five four-letter groups.
Message setting, B-H-B.
"A-V, V-K, A-K."
Check.
Yeah, me too.
- "M-S, S-M." - Check.
Two loops. Confirmed?
And no clashes.
1 0:04.
One down.
Now the wolves will be gathering.
Still nonsense. Why?
Can you fix B-D-1 61 1? Convoy speed and direction same.
New position: K-A-F-V, N-C-L-A.
Skynner's offered a bottle of Scotch to the first man to come up with a menu.
- Does he know I'm still here? - He didn't ask.
Oh, Puck, there's a message left for you at the switchboard.
It's Adelphi 4-2-4-3.
There's no name, and I'm not your social secretary.
- Message key: R-M-U. - Sorry, Guy.
How much more material do you need?
We've got 9 signals. Another 20, 25 would be better.
Suppose it starts before you have them.
Naval grid square B-D-1 386.
Course: 70 degrees. Speed of convoy: 1 0 knots.
I'm pretty sure there's enough for a stab at a menu. Let's try it.
- You have 1 7 contacts, Mr Jericho. - It's not enough.
Well, why the hell not?
When I'm done, we'll be looking for a needle in a haystack...
but if we stop now it'll be a hundred thousand haystacks.
You know that.
Full moon. Ten U-boats, somewhere.
Thirty-seven merchants, five escorts, one of which has lost contact with the convoy.
No rescue ship and no air cover.
Eighteen.
- Flower down, 2-6-8 degrees. - It's what you might call a bitch.
- Twenty-three. - Not enough.
- What have you got? - I need one more link.
I can't see it.
Names. They're names.
- You? - No.
Getting a very bad feeling now.
Polish names.
- There. - Yes.
- Menu. - Let's hope to God it works.
It's started. Bastards.
Don't you have homes to go to?
- How's it going? - Four hits so far.
Probably 300 men lost.
A Dutch cargo and a Norwegian freighter went straight to the bottom.
And an American liberty ship's on fire.
Half the crew are drowning. The other half are trying to save them.
Tom. Unfinished business.
Congratulations.
It's a half bottle, as it turns out.
Typical Skynner.
That should go back.
Where's the museum key?
Oh, sorry, Guy. I've still got it.
Tsk, tsk. Security around here.
Then get off home, old thing.
-Haven't you got a girl waiting for you? -She's dead.
Tom.
Oh, my God. Come on.
- What? - Come on.
It's Polish.
Polish names, all of them.
The Germans found a mass grave.
Look, doesn't it say 4,000 corpses?
"Polish officers buried in the forest at Katyn in 1 940...
"during the Soviet occupation.
Shot in the back of the head."
Murdered by the Russians.
By our Russian allies.
They were comrades-in-arms against the Nazis.
My God.
That's why the file was empty-- on the orders of Secret Intelligence.
And that's why Beaumanor was ordered to stop intercepting the signals.
It was too big a secret.
Just knowing that can get you killed.
And Claire discovered it.
Copied it into the German book, and she had to tell...
someone.
- Adam Pukowski. - What?
Missing in action.
Kid brother of Jozef Pukowski.
Claire stole those intercepts for Puck...
because he was looking for his brother's name.
- Puck! - Wait! Please!
This Puck killed her. Why?
Because he had a secret, too, and she could've given him away.
- What secret? - I can't tell you that!
Tom!
Hello. Could you get me London Adelphi 4-2-4-3, please?
I'm sorry. That number is not in service.
What the hell is this about, you and some skirt waltzing around Beaumanor?
Leonard, unless you're asking me to dance, let go of my arm!
I should've cooked your goose when you made a fool of yourself over that blonde...
who fucked half the park.
What?
Stand away! Stand away!
What the bloody hell do you think you're doing?
He's two carriages up. Snug as a bug in a rug.
Morning, sir.
You knew?
About Pukowski?
We had no proof, but when Miss Romilly went missing--
- Puck and Claire were having an-- - Were seeing each other, as you like to put it.
Seeing each other's brains out.
Jozef Pukowski, who'd been wondering what could have happened...
to all those Polish officers who hadn't been heard from since the first year of the war...
and Claire Romilly...
who was reading the Wermacht traffic from the Eastern Front.
They were made for each other.
And lo, mass graves.
Polish uniforms, names.
- We've been bracing ourselves for the Nazi propaganda. - Propaganda?
Four thousand Poles murdered by Stalin?
It's what Hitler would give his last ball for.
Think of all those Polish names in the U.S. of A.
Think of our convoys full of American goods...
some of them in American ships...
running the U-boat gauntlet so our supplies can keep Stalin in business.
- But it's true, isn't it? - The Katyn massacre?
Oh, really, do shut up. There's a war to win, and Stalin's helping us win it.
And they hate the Russians, you know.
They've hated them for centuries.
So what's Pukowski going to do to get back at them?
Help the enemy. That's what.
His enemy's enemy.
And he's got a big piece of knowledge that can help the Germans-- Shark.
- The weather code. - Claire couldn't have known what he'd do. She wasn't a traitor.
I'm sure you're right.
But then Pukowski heard that you were coming back.
Jericho, the lover who wouldn't let go, who'd cracked once before.
The swot who was invited to the ball, found Cinderella's slipper...
and went so crazy he would've told her anything.
And you would have, wouldn't you? About how we lost Shark.
And the rumour that there was a mole in the park, probably in your hut.
How long would it have taken Claire to work out that the traitor was Puck? About a minute.
So he killed her.
One-way to Manchester, according to the ticket collector.
Change the watch.
Well, let's see where and to whom he will lead us, hmm?
Train approaching, platform three.
It's the 3: 15 to Manchester.
How do you get the petrol coupons to go zipping up and down to London?
Secret, darling. I know a chap.
Train standing, platform three. 3: 15 for Manchester only.
Manchester, next stop.
That's it for you.
Go home, keep your head down...
and I might try and forget about you and your moll breaking the Highway Code...
and the Official Secrets Act on the same day.
Train standing, platform three.
3: 15 to Manchester only.
You've been trying to frighten me into keeping my head down right from the start. Why?
Because somehow I frighten you. Why?
Because of Claire. My connection with Claire.
Be careful now.
The night you came to my room, you already had Pukowski in your sights...
yet you went out of your way to play the heavy with me.
And then you were more concerned about Claire Romilly than you were about Shark.
- A girl who'd missed her shift? Why? - Why? She was his girlfriend.
Oh, no. She was more than that.
She was working for you. Claire was your agent.
She told you everything, even how I found her shoe.
As you said, Bletchley was a security nightmare, so you put a girl in the park to do your dirty work.
Surely you mean her patriotic duty.
Everything that she did, she did because you told her. You had her fucking for England.
And then when she got to Pukowski, it went wrong. She took pity on him...
and she told him what she was writing in the German book.
No wonder you were frightened.
You'd made a terrible mistake, and your agent paid for it with her life. Claire.
He's jumped!
He's gone!
Come on! Back it up! Back the train up!
What are they doing?
Sir, please. The station's clear. Roadblocks are in place.
- Search the train again. - He's not on the train!
- We'll have to let it go. - Please be patient.
Oh, Puck, there's a message left for you at the switchboard. It's Adelphi 4-2-4-3.
- Keep the change. - Thank you very much.
- To the station, rather fast, please. - Ma'am.
You bloody idiot. This time I can't save you.
You broke Skynner's cheekbone.
Tom. Well, weather code is, uh, c-c-cracking open.
Where's Puck?
- Check our weather report-- - How bad is it?
It's bad.
But we are reading Shark, thanks to you lot.
- What's this? - Grid square A-M-2-9. We think it's a garbled signal.
- Signal to a U-boat? - Mmm. U-61 7.
Ordered out of battle to proceed immedi--
Yes?
Where is this?
Loch Feochan, in Scotland, where I'd like to be old. If I'm ever old.
So, it's the real thing. U-671, rendezvous in 24 hours.
Our turn to find a sitting duck.
My God.
- Be careful. - I will.
Damn it.
- I'm on the chosen frequency. - Sir.
- There's probably interference. - Swing around. I'll fine-tune it.
Perfect.
Just in time to bugger up the whole operation.
- Do you want to abort? - Are you serious?
- I didn't kill her. - I know.
Do you think I'm here for that?
- That's right, my darling. - They're ready.
Up you come.
What about the rest of it?
The real secret you want to tell the Germans, about how we really broke the code?
- About my machines! - Thomas, Thomas.
- You can have your enemy. Let me have mine. - No.
Well, shoot me, then.
- It's your show, but your man-- - He is not my man.
Serve it up.
- Go ahead. - Tell Auntie Mae the package is ready.
Dinner's ready.
Bullseye!
- Run out a couple of yards there. - You're looking in the wrong place.
Oh, it's Mr Jericho.
Come home again with his batteries dried out.
You turned out to be some swot.
- I tip my hat to you. - She's not there. Didn't you hear me?
She's moved on.
The murder scene was like a pile of clothes left on a beach.
Sometimes it means somebody's dead.
Sometimes it means somebody wanted to disappear.
Like an agent who'd been turned by her target.
It was you who saw it before I did.
What makes you think that?
Pukowski was on the train, and you were letting him run.
He knew the secret that could lose us the war. Remember? The thinking machine.
You were holding back to see who he would lead you to.
Who the hell could it be to make you take that risk?
Only Claire.
Well, I was wrong, wasn't I?
She wasn't with Pukowski.
She was waiting for him up the line to take him to her little Scottish hideaway...
where a couple of runaway lovers could sit out the rest of the war.
Do you think I didn't check?
She loved him, and Pukowski brought her all the way to the brink...
but then he had to tell her what she didn't know...
about the U-boat coming to pick him up, and why.
If they got caught, they'd both hang.
But there was no going back. Only forward, to Germany.
But then, he didn't know Claire.
She was no traitor.
She's out there, somewhere...
like a sword hanging over your head.
In different ways, she fooled us all.
She was unreadable.
- Stick to sums. - I think I've got something! Easy does it!
What have you got there?
Steady.
- We're losing her, lads. - Do you want it to be her?
Steady, now.
False alarm!
Shut up.
Keep looking.
Oh, I will.
I will.
- Sorry I'm late. - It's all right.
I was getting worried about you two. (Subtitle Revised by HchC)
