"Paris Green."

Zhou Erya carefully removed the core of the cherry with a silver spoon, and then mixed the fresh cream and put it in her mouth, only then did she give Han Yu a reply.

"What?" The second monk Han Yu was puzzled and didn't touch the dessert in front of him.

Unlike Zhou Gongzi, who loves sweets, Han Yu doesn't like desserts very much, and even if he eats desserts, he will not be as elegant as the handsome young master in front of him.

"Aren't you wondering where the poison is? The siren's hair is algae green, a vivid green color that is probably the 'Paris green' favored by current painters, and the pigment of Paris green contains arsenic trioxide, which is the ingredient of arsenic. ”

Zhou Erya tasted the sweet fruity aroma brought by the tip of her tongue and explained lightly.

"So, the question of the source of the poison has been solved?" Han Yu was a little discouraged, thinking of those artists who committed suicide due to depression, "Is it really suicide?" This...... It's a shame. ”

"Nope."

Zhou Erya put down the spoon, and her long white fingers gently tapped the rosewood tabletop, and only after a long time did she frown and mutter: "This matter is still strange, if the mystery of the kraken is not solved, it is impossible to see the real truth." ”

"Kraken?" Han Yu was excited, he felt that this was not a problem at all, and he was only immersed in the pity of the talented girl's suicide, "No matter how you look at it, it is difficult to think that there really is a surreal kraken, it should just be sea blues." ”

At this time, Europe was the most popular time for Professor Freud's psychoanalysis, and it was found that many of the problems of evil or demonic possession in the past could be explained by psychological diseases.

When Han Yu was studying in Germany, he also audited several psychoanalysis courses, and he cannot be called an expert, at least he has his own experience.

"Using psychoanalysis to characterize this case as a suicide is not illogical, it's just a lot less interesting."

Zhou Erya spoke slowly and methodically, and there was always an invisible light hidden in those deep eyes.

"Fun?" Han Yu glared at Zhou Erya with disapproval.

He liked this new friend very much - not so much liking as worshipping, but it was undeniable that Zhou Erya was very indifferent to the emotions of others, and only this made it difficult for the sincere and frank Han Yu to accept.

Just like now, this noble son thinks that the case of the girl's suicide is not interesting.

"Behind this Siren's story, there should be a more exciting plot." Zhou Erya knew Han Yu's dissatisfaction, but he didn't care about other people's opinions, his interest was raised by the case, and he wanted to find the dark truth behind it.

"That's not a scientific attitude." Han Yu muttered.

In the past few days of getting along, Han Yu knew that Zhou Erya was a strange person.

Zhou Erya studied in Europe, but instead of mathematics, chemistry or mechanics, which are leading things in the West, she studied occultism and folklore, and got a double doctorate.

This person's knowledge is so extensive that it can be described as an encyclopedia, so Han Yu didn't feel strange at all that he broke the fact that the paint contained arsenic.

No matter what he talks about with Zhou Erya, he can pick it up, and his views are unique and deafening, so Han Yu especially likes to communicate with him.

It is precisely because the thoughts are too deep that sometimes the speech is mysterious and unpredictable, and it is difficult for people to keep up with the train of thought.

Han Yu always believes that "this is not a scientific attitude".

The way of working in science should be to continue to ask the relevant person, and after getting more information, then analyze and reason.

So the next morning, when Di Wei recovered a little, Han Yu asked him again about the Kraken case.

Because Di Wei was not feeling well, the only Chinese doctor in the second class was accompanying her.

She was half-leaning on the bed, Xing Zhili waiting, taking a pillow to cushion her.

"Can you tell me more about the Kraken?" Han Yu asked straightforwardly.

Hearing the word "Siren", Di Wei's face turned pale, her eyes turned red, and she began to tremble again.

"Would you like some water?" Seeing her reaction, Han Yu felt a little cruel and discussed with her something she didn't want to recall.

Devie shook her head, "No, thank you." ”

"That'...... Mr. Chen had something to do with me yesterday about the Kraken, and he said that Miss Rong seemed to have a nightmare the night before. Although Han Yu couldn't bear to let the lady talk about topics that she didn't want to talk about, in order to find the truth, she continued to ask, "Can you tell me what happened that night?" ”

Hearing Han Yu's question, Di Wei held on to her spirits and replied with tears: "Not bad." I should have noticed that Jiafan hadn't been normal since the night before. After lunch, we were in the room to rest, and suddenly I heard a hazy and beautiful singing, at that time I thought it was a performance on the ship, saying that this vocal range is so high and bright, not ordinary people can do it. ”

Later, Jia Fan didn't know why she thought of the Siren, she became very frightened, and couldn't sleep in the middle of the night, so she pulled me to chat, and told me some terrible legends on the sea, and then I fell asleep because I was too sleepy, and I woke up in the middle of the night and found that she was in a daze at the picture she had drawn, and the moonlight shone in through the porthole, and I saw ...... Seeing that her face turned pale. ”

Speaking of this, Devi's face turned even paler, and the scene seemed terrible, and she tried her best to calm her mood, and after a while she continued:

"Jiafan said to me that the Siren was calling her, and that she was about to go to the New World, and her expression was very terrifying. I was frightened and persuaded her, but she just smiled coldly and picked at the picture with her fingers, because it was stained with paint, and the fingers were all green......"

Di Wei's spirit seemed to be greatly traumatized, her voice became more and more trembling, and she looked at Han Yu with tears: "I don't know what happened, it's more like I had a nightmare......"

"I'm sorry for making you remember such a sad thing." Han Yu would not comfort people, and said to her dryly.

He regretted that he couldn't drag Zhou Erya over, and always felt that Zhou Erya was very good at handling women's emotions.

But when she woke up the next morning, she was much better. I thought she was just in bad spirits for a while, so I didn't care. Didn't expect ......"

Di Wei didn't finish speaking, lowered her head, pulled the thin quilt to cover her face, and couldn't cry.

On the other hand, Xing Zhili took out a handkerchief from his pocket and handed it to her, and said comfortingly: "Miss Di, the mourning is smooth, you also have to take care of your body, this hurts your body, and it is really difficult to recuperate on the boat." ”

When Han Yu saw the handkerchief, he suddenly thought of the girl whose handkerchief was blown away.

He shook his head, hurriedly wrote down everything Di Wei said in a small notebook, thought about it and asked, "What time did you two hear the song at that time?" ”

"What time is it?" Di Wei's expression was a little dazed, and she thought about it for a while before she said, "It was probably two or three o'clock in the afternoon the day before yesterday." ”

Stamp. Duyang's afternoon was particularly lazy, the passengers were resting a lot during that time, most of them were taking naps and recuperating, and the ship should be quiet, but no one had heard the singing except for Di Wei and Rong Jiafan.

The investigation was at an impasse, Han Yu sighed, closed the notebook, and asked again, "In addition to these, what other unusual things happened around Miss Rong?" ”

Di Wei thought for a while and hesitated: "A few days ago on the deck, I seemed to see Mr. Zhang pestering Jiafan to talk, but when I walked over, Mr. Zhang left immediately, and Jiafan didn't say anything. I can't think of anything else abnormal, Jiafan's life is very regular and simple, except for eating, walking, blowing the wind, most of the time in the cabin painting. ”

Han Yu frowned, "Mr. Zhang? Is that Zhang Houde? ”

Di Wei nodded tiredly: "Yes." ”

This can be regarded as a clue, although Han Yu doesn't think that the lustful fat man Zhang Houde has the courage to kill, but he has to ask about it.

"Don't disturb your rest, if you think of anything, come back to me." Han Yu put away the notebook, finished speaking to Di Wei, and turned his head to look at the criminal doctor, "It's also hard for the criminal doctor to take care of it, if there is anything that needs to be done by me, just call me." ”

The criminal doctor's face was also full of exhaustion, obviously not resting well, he nodded: "Leave it to me here." ”

Han Yu didn't say much, and after leaving Di Wei, he went to Zhang Houde to understand the situation.

Zhang Houde frowned, but he didn't dare to deny it: "I did meet Miss Rong on the deck on Tuesday, and I just wanted to invite Miss Rong to dance at night, but she was not interested, so I touched my nose and left." ”

Han Yu felt that he was very slippery, and said deliberately: "Someone has seen that you have been pestering Miss Rong for a long time. ”

Zhang Houde was frightened, looked around with a sad face, for fear of being heard, and begged in a low voice: "Mr. Han, you whisper, what else should I do if this is going to get out?" I admit that Miss Rong is so beautiful, I have some crooked thoughts, and when I go out, even if I am a dewy couple for a few days, what can I do? It is not easy for a single lady to go out alone, and I am willing to sponsor one or two travel expenses. It's just that Miss Rong is thin-skinned, and she was annoyed at the time, and everyone is watching, where do I have the courage to entangle? ”

He lowered his voice and shouted, "As for Miss Rong's accident later, it has nothing to do with me. You can ask my companion if I haven't spoken to Miss Rong since then. ”

As soon as Rong Jiafan died, Zhang Houde was in a panic, for fear that others would suspect him. When Han Yu asked at this time, of course he hurriedly confessed.

Han Yu asked Zhang Houde's companion Fang Zhongzhi, as well as a few people on the same boat, and sure enough, Zhang Houde did not look for Rong Jiafan again, with his character, he did not dare to poison, not to mention that he lacked the opportunity to do it.

This clue seems to be of little use.

Han Yu showed the record of the interrogation to Zhou Erya, and Zhou Erya shook his head and said: "The day before yesterday was Friday, and two or three o'clock in the afternoon was the rest time, and there was no performance on the boat. It seems that if they didn't hallucinate at the same time, they really encountered a kraken in broad daylight. ”

"I think it's because they have heard too many horror stories about John Chen, and there are psychological hints." Han Yu is an intellectual who has received progressive science, so he doesn't believe in ghosts and gods, "In the world of science, there can't be anything like a kraken, can I understand it as an auditory halluciation caused by mass psychosis?" ”

The artist is somewhat neurotic and falls into the category of completely understandable.

Also as a painter, Mr. Van Gogh pierced himself in the abdomen with a pistol more than 20 years ago.

"She was by no means suicidal."

Zhou Erya objected to Han Yu's conclusion.

Under the bright light, his eyes reflected a cold glow, and his white jade-like side face was carved out of marble, and for a moment, Han Yu felt that he was not like a fresh and hot human being, but more like a god, or ...... Ghosts.

Zhou Erya finally took the initiative to make a request: "I want to see her paintings." ”
