Cheers.

Any more wine?

No. I'll buy some more.

No. Let's stop here.

Notify Adou to bring a bottle of iodine

and search the trash cans around the ballroom carefully.

What will he look for?

Evidence, of course.

You finally came around?

Tell Inspector Qiao.

Don't use handcuffs on her.

That's the only thing

I can do for her.

Miss Zou, this is Mr. Norman.

Pleased to meet you.

Please take a seat.

Thank you.

I heard a lot about you from your sister.

My sister, Really? What did she say?

She said you are quite clever,

and beautiful from a young age.

And you'll have a happy and bright future ahead of you.

I no longer hope for any happiness.

I'll just be lucky enough to be alive in Shanghai.

I understand, but I think that medicine factory still has lots of potential.

To be honest, I don't think I am suited for that kind of work.

Come on. You're quite a genius,

especially given the explosion that you created.

I think you would be able to make

lots of things with our resources.

I don't know what you're saying.

I planted an informant with your sister.

From the beginning I've been watching your every move.

So why didn't you stop me?

Your sister had a big appetite you know.

You are a well-educated girl.

You've received your higher education in Cambridge.

I feel it would be much easier for us to find a way together.

Hail Cambridge grads?

Let's make a toast to our successful future working together.

Qiao Chusheng, what are you doing here?

To arrest a suspect, of course.

Miss Zou, please go to the police station with me.

The charge is?

She created that explosion.

Me?

Do you have evidence?

Do we have to say it here?

If you don't make it clear, I won't go with you.

Fine.

Then allow me to

sort the whole thing out.

If I get anything wrong, please do correct me.

Your sister Zou Ying and Mr. Bai were doing business together.

At first the business went well.

But she was not good at business

which led to a severe imbalance.

To make up for the shortfall

she used the staff of the medicine factory

to extract heroin from opium.

Then she smuggled the heroin to Hong Kong and made a lot of money.

But what she did also offended Mr. Bai.

In order to find a new patron,

she forced you to marry Mr. Huang as his concubine.

It thus created an irreconcilable rift

in your relationship.

I killed over such a reason? I don't think so.

Besides, I am a weak woman.

Where did I get the explosives?

It's not any explosive that caused the explosion,

but flour.

Flour can kill people? I've never heard of it.

The reason why flour can explode is because…

Wait a minute.

The reason why flour explodes

is the dust has a larger specific surface area.

Compared to clumpy material,

dust has a strong chemical activity

and large air contact area.

It can adsorb a lot of oxygen molecules and cause a fast exothermic oxidation.

When under an opportune conditions,

any ignited dust

will create a violent combustion reaction

and instantly release huge energy.

That is to say

when every cubic meter of air contains

9.7 grams of flour,

there will be a violent explosion.

You were there that night.

Where did the flour come from?

Spouted from the dry ice machine.

There were six dry ice blasting machines on the stage that night.

Five of them were indeed filled with dry ice,

but one was filled with flour.

When the show started,

five machines started at the same time,

and the dry ice formed vapor.

After the mist was mixing with the flour particles,

because cold air has lower quality than hot air,

water vapor sunk.

Soon

the only thing left on stage

was flour particles that don't flow easily.

The dust concentration in the air was increasing gradually.

After Zou Ying sang that song and

took a photo with Chairman Liu,

the reporter's flash lighted the dust.

Then a violent explosion occurred.

Even so,

how can you prove that I put the flour in the machine?

It's easy.

After the incident

you learned that Lu Yao would come to investigate the case.

You knew he was a good detective,

so you decided to venture back to the scene

and wipe the inner wall of the machine's spray gun clean.

When he investigated the scene last night

he found the spray gun that you wiped clean.

So many people were there that night.

Why did you guys point at me?

Your fingerprint is on the inner wall of the spray gun.

The handkerchief you used to wipe it

was dumped into a trash can in the back alley of the ballroom.

It also has your fingerprint on it.

And at the back alley we also

found some traces of carrying flour.

But after spraying iodine, the flour changed color.

We found your footprints on the flour

which led all the way to the backstage of the ballroom.

How did you guys suspect me in the first place?

Your shoes.

Shoes?

At the night of the bombing,

you were wearing a pair of black high heels.

In the police station the next morning,

you claimed that you didn't go back home all night.

But you changed to a pair of red high heels.

This strange thing

raised Lu Yao's suspicion.

In the trash can in the back alley of the ballroom,

we found those black high heels.

This shows that you knew

your shoes would get stained that night beforehand.

At your home

you rummaged through the trash can for a lighter.

You don't smoke, your sister smoked.

So before leaving home,

you knew your sister would never come back home.

That was why you threw her lighter

in the trash can.

As for flour

it was written clearly on your ledger that

your family spent twenty silver dollars just three days ago

to buy flour and rice.

In your kitchen Lu Yao

there was only a thin layer of flour left.

He inferred from this fact that the explosion was caused by flour.

So I was self-defeating.

I guess you gave me the ledger and the bullet

in the hope that when we found the lead was tied to Mr. Bai,

we would close the case and leave it unsolved, right?

I am blessed to have such an ex-boyfriend.

I finished my speech.

Can you go with me now?

Bravo!

It's wonderful to see the process of a case today.

It's so wonderful.

You're welcome.

What is this?

We found it at Zou's house.

Times with a Shanghai twist.

After careful cross checking, we found

this is slightly different from the original one.

What do you mean?

This newspaper is customer-made.

It was printed only for Zou Jing to read it.

And on the paper

there is a lot of interesting content.

A flour mill's big explosion,

and the working principle of dry ice blast machine.

I think Zou Jing must have gotten her criminal inspiration

from the information.

So compared to this case itself,

we are more interested in

the clues behind the case.

Excuse me, what are you suggesting?

I wouldn't dare.

I just hope

you can let Lu Yao stay.
