Elementary

Previously on Elementary...

If you're looking for Sherlock, he's downstairs.

Okay.

His name is Harlan Emple.

He is the Rachel P. Hanson Professor

for Applied Mathematics at Columbia University.

What I don't get is why he isn't wearing a shirt.

He doesn't like anything to come between him and the numbers.

What is it?

The answers to your questions about Kitty.

The truth is she was a victim of a horrific crime.

After you left last night,

Sherlock gave me an envelope.

Sherlock keeps saying

that I need to get a better sense of you,

and maybe that will give you a better sense of me.

It's open.

It's nothing.

It's Sherlock and one of his experts.

Which one?

Phillip something.

Must be new.

He's a knife-thrower.

Why does Sherlock have a knife-thrower?

He got bored the other day,

started looking into this, uh, circus accident from the '30s.

The Great Galardo perforated one of his assistants during an act,

except Sherlock thinks the blade was thrown

by somebody in the stands, not Galardo.

Phillip, as far as I can tell, disagrees.

It can't be done, okay?

It was done.

You're wrong.

Nobody can chuck a knife that far.

What's this?

You're...

Not here.

I'm not here.

Remember that, okay?

Oh, yes. Heaven forfend your work

with me should endanger your precious day job.

You throw knives?

You know, it was supposed to be just you here.

Phillip is arguably the greatest knife-thrower in the world.

Has been for decades.

Only, there's little money

to be made in the impalement arts.

So, as a youth, he turned

to what you Americans term “football”"

Is this a joke?

Phillip, head and heart.

Come on. Head and heart.

Can I go?

Yeah.

15 years he spent throwing that misshapen ball around.

15 years.

When I think of the acclaim he could have brought

to competitive blade slinging.

You're following me, Watson.

I don't like it.

I want you to help me with something.

This is Chad Keswick.

He buys distressed buildings,

paints, spackles,

and then flips them for quick money.

Who'd he kill? No one.

I was hired by one of his rivals to find out

why he's been circling this old office building

in Jamaica, Queens.

She wants to know why he thinks

the building is a good investment.

Is there a crime in there, something worth investigating?

Well, I've been shadowing Keswick,

but yesterday I think he noticed me.

I want to switch up the tail.

You followed me for over a week before I noticed you.

Help me out, and I'll cut you in on my fee.

I don't work for you, I work for Sherlock.

I worked for him, too.

And, in my experience, he was always supportive

of taking on work outside the partnership.

Sorry, it's not my cup of tea.

Hello, Portal Ten.

I'm here, Belphegor.

So where is the next clue?

== sync, corrected by elderman == @elder_man # Resynced for WEB-DL by peRFecterer #

Look, for the last time, I was playing a game!

Yeah, you called it a puzzle hunt.

Belphegor's Prime.

Think Cicada 3301 or Octorine's Challenge.

They're math games.

Math-- maybe you've heard of it.

I've got some math for you.

One dead guy plus one live guy

found in the same deserted factory.

I was not “found” there; I am the one who called 911.

I was waiting there for the police.

Mr. Emple,

we're just trying to do our jobs, all right?

First officers on the scene described you

as “extremely agitated.”

Well, of course I was agitated.

I had just found a dead guy in mothballs!

And did I mention that I have not slept in almost two days?

Because of the math game.

Can I borrow those?

This...

is Belphegor's Prime, okay?

It's a numeric palindrome.

It's 666 bookended by 13 zeroes and then bracketed with ones.

Named for the demon Belphegor who was a prince of hell.

The first clue for the hunt, it started making the rounds

a few months ago.

It was a JPEG with two numbers hidden in it.

You divide those numbers by Belphegor's Prime,

and you get the GPS coordinates for a restroom at the Bronx Zoo.

You go to the restroom, you find a phone number.

You send a text to the number, you get the next clue.

Which is another math problem.

Exactly.

Only, this one is harder.

And that's how it works.

You know, but for each one that you solve,

you get a new set of GPS coordinates.

And that means that you've completed a stage, or a portal.

And last night, I was on Portal Ten.

And...

You know what?

I want to talk to Sherlock and Joan.

Look, Mr. Emple... No, I'm sorry.

I told the police down at the factory that I know them.

Isn't that the whole reason

that I was brought here to this squad?

I-I am not saying another word until they are here.

Harlan Emple is indeed an acquaintance.

He is, in point of fact, one of my “irregulars.”

One of your what?

Irregulars.

I'm your consultant, Captain; they are mine.

They're a handful of experts I turn to

when I encounter problems which are beyond my pool of knowledge.

Harlan is a brilliant mathematician.

And on the handful of occasions I have tackled a case

which pertained to mathematics...

He helped you out. Well, the good news

for him is the preliminary autopsy report just came in

before you got here.

And the M.E. puts the time of death

between 4:00 and 6:00 p.m. last night.

Mr. Emple was teaching

a class at Columbia.

So the victim is yet to be identified?

No I.D., no phone.

First detective on the scene liked it for a mob hit,

so while we're running the prints,

he's showing the vic's face around OCID.

Marcus here was about to walk the scene with Mr. Emple.

You're here now; you might as well tag along.

Actually, Captain, I'm quite busy today.

This is a John Doe, and we got nothing.

And, like you just said, you're my consultant.

So, go consult.

Watson.

Um, he's your friend.

Actually, Kitty is otherwise engaged,

and he did actually help both of us with a case last year.

Did he not?

Have I told you how good it is to see you?

Yes, you have. Three times.

Well, it is.

Hey, lousy circumstances.

But, uh, hey...

I heard from your boss that you just, uh, got back from London.

Were you working a case or...?

No, I moved back there.

You mean moved, moved?

Is there another definition?

I was there for eight months,

and had a change of heart and returned to New York.

So, you moved to London, and you didn't, uh...

You know what? Doesn't even matter.

The point is you're back!

Mr. Emple. Uh, duty calls.

Yeah.

It's interesting.

Mothballs are interesting?

They were taken from that cabinet over there.

Obviously, to cover the smell of John Doe's decay.

The killer didn't bring them with him.

Perhaps leaving the body here was not part of his plan, hmm?

Doe was shot in the foot first and then the knee.

Either those were two really bad misses or...

Or the killer was torturing him.

This doesn't seem like anything you can't handle on your own.

So you want to tell me why you really asked me to come here?

“This doesn't seem like anything you can't handle on your own.”

That's funny.

That's exactly what I would have said

had I been present when you asked Kitty for her assistance

with your tawdry side job.
