When Chen Yan first entered the gallery, he discovered something was wrong.

Zhao Danyang is still dressed as he was when we met him in the morning, but the smell of perfume is gone!

Have you taken a shower?

Give me a break.

Even if you take a shower at noon, you can't wash away the smell of perfume from your clothes, right?

However, the taste disappeared so suddenly.

Of course, when Chen Yan met Zhao Danyang in the morning, he did not activate the olfactory gene lock.

However, by frequently turning on the olfactory gene lock, Chen Yan's own sense of smell has become very sensitive.

Moreover, the feedback and feelings about smell are much more detailed than before.

Therefore, when Chen Yan saw Zhao Danyang again, he immediately discovered something different.

Later contacts confirmed Chen Yan's guess.

Zhao Danyang suddenly became a little unfamiliar with Chen Yan.

In the morning, Chen Yan and Zhao Danyang had a deep chat.

After all, Zhao Danyang told Chen Yan many secret things.

Zhao Danyang also always called Chen Yan Mr. Chen.

However, during this meeting, Zhao Danyang called Chen Yan Officer Chen.

Also, when passing by the painting of the girl in the wheat field, Zhao Danyang's eyes did not even pause.

You know, this painting means a lot to him.

The two of them had just finished their discussion in the morning, and now they didn't even look at each other?

Next, the picture of the rising sun in the studio confirmed Chen Yan's guess.

The system rewards Chen Yan's painting expertise, giving Chen Yan an extraordinary understanding and knowledge of painting.

Chen Yan can tell whether an oil painting was painted by one person or two people at a glance.

You know, this is Zhao Danyang's studio.

Besides him, who else could touch his painting?

However, Zhao Danyang actually lied.

Some things, when no one notices them, are like ghosts in the dark that can hide in the darkness forever.

But once the sun shines, there is nothing to hide.

Chen Yan just took out his cell phone to send a message to Wang Min, leader of the Ninth Detective Team of the National Detective Corps.

Thoroughly investigate Zhao Danyang’s study, life and work experience abroad.

This is not difficult.

Naturally, I can't find anything very detailed. After all, four years have passed.

However, as long as there is some important information, it is enough.

For example, Zhao Danyang met his twin brother by chance abroad!

"Officer Chen," Zhao Danyang's face was slightly surprised, and he looked at Chen Yan with a puzzled look: "What is Mr. Jim?"

"Did you make a mistake?"

Mistake?

Chen Yan shook his head.

"Seven years ago, the second year after you went abroad, you did a DNA nucleic acid comparative test."

"St. Paul's Hospital...the name of the comparison subject is...James Jim!"

Chen Yan looked at Zhao Danyang, who was already looking dull: "I happen to have the comparison test report at that time on my phone."

"Do you still want me to read out the results?"

…

Hulu City Detective Interrogation Room.

Chen Yan, Qin Chuan, Huang Guojun and others all looked at the screen in the monitoring room in surprise.

Two figures with different movements on the two screens have exactly the same appearance.

Clothing, hairstyle, accessories...

Wait, everything is exactly the same.

"Team Leader Chen...how did you find out?"

It's not that Huang Guojun has never seen twins before, but it's the first time he's seen twins who look exactly the same and can't tell the difference between real and fake twins with the naked eye.

Not only Huang Guojun, but also Qin Chuan's eyes were full of surprise when he looked at Chen Yan.

You know, Zhao Danyang has a very clear alibi.

There are surveillance records from the train station, the investigation report from the capital, and some video evidence.

It all shows that Zhao Danyang is not in Hulu City at all.

How can one commit a crime if he is not at the place where the crime occurred?

Therefore, Zhao Danyang's suspicion has long been eliminated.

But Chen Yan actually ran out quietly when all clues were interrupted.

Just caught the murderer?

When the two appeared in front of everyone, everyone understood what was going on.

It's nothing more than one of the twins playing the role of Zhao Danyang, and the other committing the crime after becoming invisible.

The method is not clever, but it works.

The simplest tricks are often the most effective.

substitute.

The hardest part is finding a substitute.

And Zhao Danyang's stand-in is perfect.

A person that no one knew, even himself, had never known before.

trial room.

The interrogation room where James Jim was held.

Chen Yan looked at James Jim quietly.

This time it was definitely James Jim.

Because this person was brought back from the airport by Chen Yan.

Chen Yan was lucky, because if Chen Yan and the others had been half an hour later, the plane would have taken off.

Although the person can be recovered by then, the seven-day deadline for solving the case may not be enough.

This man has James Jim's passport on him.

And that familiar perfume smell.

"We meet again."

Jim nodded: "Mr. Chen, how did you find out?"

Jim was a little confused: "We two brothers look exactly the same."

"Except for flying, we can't exchange each other when verifying our identity. We can do it at other times."

Chen Yan nodded.

Hulu City is not close to the capital.

Flying is actually a better choice, but Zhao Danyang chose the train to travel back and forth.

Maybe that's the reason.

The airport security system is very strict.

The security machine scans the face and compares not the appearance, but the data.

For example, the distance between pupils, such as the intersection ratio of nose and face, etc.

In adults, due to the fixed shape of the skull, this data does not change easily.

And James Jim and Zhao Danyang, even in the eyes of others, are exactly the same.

However, there are still differences in the precise data of the two faces.
