I've been good to you.

Then you understand why it's hard for me to accept…

that you just want to leave.

Our home is always open to friends.

-Who is your guest, Ajay? -Oh, you're the gem dealer.

He is the gem dealer. My husband, Alain.

We have a network of couriers throughout Asia

and Western Europe.

Which is how we are able to offer such attractive prices.

To friends.

To friends.

-To friends. -What's wrong with us?

To friends.

I'm looking for two backpackers.

I work for the Dutch embassy.

Their families haven't heard from them in over two months.

I have letters they wrote home in which they both describe

meeting a French gem dealer based out of Bangkok.

Do they name this French gem dealer?

No. But if this killer is not found, people are in danger.

What is my risk next to that?

What is your risk?

See, this is what he does.

He robs. Kills. Forges victims' passports.

He's the man known as the Serpent, Asia's most notorious killer.

What did you make me do?

You are a killer too.

Nobody has ever caught me.

I expected to feel great guilt.

I did not. I felt free.
