Embankment Mutsu River, river bank.

An iron bridge crosses the river, and vehicles pass over it, and there are many iron bridges that connect the two sides of the river, just as Mito Moon does not know how many murders in Tokyo are related to the Tsutsutsu River.

If the holy place of suicide in Japan is the Aokigahara Forest, then the holy place of murder should be the Timatsu River.

"Click, click."

A hatchback used by the robbers collapsed on the bank of the river, and the billions in cash in the open trunk had long disappeared without a trace.

The police officer of the forensic division took a camera and took pictures around the light-faced car, and I didn't know which car was shooting the scene in the field.

"It's hard work, what's the result of the identification?"

Officer Twilight, who had arrived from the bank, walked down the riverbank.

"Dusk Police, we've seen it all roughly, but all fingerprints have been wiped clean." The bespectacled uncle in the forensic class got out of the car.

He also wears an armband with the word "Literacy" on his left shoulder.

"Is there anything else left?"

"Ah, there are five aluminum alloy boxes in the trunk for storing cash, needless to say, the cash has all been taken away, but the fingerprints on it are also zero, and in addition, there are two accidental discoveries......"

"The prisoner left out a face shield and gloves on the seat in the car."

"But because of the material, these two things can't be fingerprinted."

Just as a few adults were talking about the situation at the scene, Edogawa Conan poked his head out: "Hello Uncle Identification, there is something stained in that mask." ”

"In the mask?"

Officer Twilight and the others looked curiously at the black mask, and underneath the mask was a death Barbie pink lip print.

"There are lip prints? Why didn't we find out just now? Looking at the lip prints on the mask, the police officers in the forensic division were a little suspicious, they had obviously carefully checked the mask when they collected it just now.

Why did you ignore this lip print at the time?

It's weird.

"Lend me a look."

Conan Edogawa snatched the mask from Officer Twilight's hand and sniffed it.

His innocent and childish face flashed with an adult-like realization.

"Sure enough...... It's weird. Mito squatted down next to Conan and sniffed the mask as well, "There are lip prints used by women, but there is no scent of cosmetics, isn't it?" ”

"Big Brother Mito......" Edogawa Conan looked up at Mito Moon in astonishment.

This is clearly what he thinks in his heart, how was it said by Mito Yue.

Could it be that he can read minds?

No, it's interesting, it seems that this lifelong enemy (pseudo) also thought of it with him.

Is this the thinking of the same kind of people?!

"What's wrong, Mito-sama?"

“……”

"Conan, explain."

Subconsciously clutching the back of his neck, Mito Moon left the opportunity to explain to Edogawa Conan, and he himself was thinking about the bank robbery on the sidelines.

There have been two high-impact and unsolved bank robberies in Japan's history, one being the 300 million yen robbery nearly 30 years ago, when 300 million yen was worth more than today's billion yen.

In the other case, shortly after the end of World War II, the prisoners 'sneaked' into the bank, poisoned 12 people, and swaggered to take 164,000 yen in cash and 17,000 yen in checks, and the poison used by the prisoners was almond-flavored cyanide.

But if today's billion-yen robbery is carried out, it is estimated that it will be talked about for decades, and the Tokyo Metropolitan Police Department will also be under unprecedented pressure.

"Conan, is there anything strange about this mask?"

Glancing at Mito Tsuki, who was contemplative, Conan Edogawa explained, "It's just very strange, if it was a female robber who could wear lipstick and wear a face mask, the mask would probably leave the smell of cosmetics, but the mask doesn't smell like that." ”

"Indeed, there is no taste, which is abnormal."

"But what's the matter?" Kogoro Mori hammered Conan's head, "It doesn't matter if the prisoner is male or female, what matters is how to recover the one billion yen that was robbed." ”

Edogawa Conan rubbed his head and looked at Mori Kogoro helplessly.

If it weren't for the anesthetic needle himself, he really wouldn't be able to take Kogoro.

I can't bring it, I really can't bring it.

"Officer Twilight, please investigate the long-haired guard, the one who was forced to carry the money by the robbers on the cash truck."

"Okay." Officer Twilight instructed the police to the west, "Brother Mito, do you suspect that there is something wrong with that guard?" ”

"It's just speculation."

But it didn't take a few minutes for Mitotsuki's guess to come true.

"No one connected to the other party's mobile phone, and according to his colleague, he went to the bathhouse after leaving the bank, saying that he wanted to take a bath to relieve his tension today."

"Lianlian got in touch, but the guard ...... It has been ...... Killed. ”

"What?"

By the time everyone arrived at the scene in a police car, the long-haired guard had already fallen to the ground and could not die again.

"Damn it! We're one step slower! ”

"He was really the bank robber's guilt, and now he was shot dead on the spot...... Is it the other two robbers who want to eat black? ”

The death of the long-haired guard was almost like a stone hammer for his involvement in a bank robbery.

Otherwise, why would an ordinary guard be assassinated with a gun after taking a bath? It's not Hirobumi Ito.

"Check! To the end, find out the life history of the deceased, credit card consumption, mobile phone text messages, and the pink lip print on the mask. ”

"Lip prints don't need to be traced, Officer Twilight."

Mito looked at the corpse lying on the ground, the long-haired guard was still pleading his innocence in front of the police in the afternoon, but now he has become a cold corpse, and things are really capricious.

"Do you already have a clue, Brother Mito?" Officer Twilight basically has to say every word with the title of brother.

"Can you send the police to investigate Miss Masami Hirota?"

"Do you suspect that Ms. Masami Hirota, a bank clerk, is a prisoner? Yes, since even the guards may be internal ghosts, it is normal for the teller at the front desk to become internal ghosts. ”

Officer Twilight has already obtained the information of the various people in the bank, and has some impressions of Masami Hirota.

Hearing Mito Tsuki's analysis, Edogawa Conan felt a little uneasy in his heart, Mito Tsuki's analysis was the same as him, and he also suspected Masami Hirota, who worked in the bank.

It's just that no matter what he says, he doesn't want to see Masami Hirota involved in this bank robbery.

Out of selfishness, this is also the reason why Conan Edogawa has never told Officer Twilight about his guess.

Seeing that Mito Moon has spoken out, Conan can only hope that things are not as he thinks.

Moreover, there was another mystery on the mask used by the prisoner.
