"Oh, why?" Officer Charlie frowned unconvinced. At this time, Chiko noticed that even Ms. Brienne, who was immersed in grief, showed a look of confusion and surprise.

"That's right, my husband and I are both chemistry teachers at Meate University, and we do have a certain amount of benzene in our lab. Before Eric could explain, Ms. Brienne confessed her identity.

"If that's the case, Lady Brienne, though you're still in a hundred thousand grief, you can't escape suspicion. Officer Charlie looked at Britney condescendingly, with eager suspicion in his eyes.

"I, I didn't. Lady Brienne's tears were streaming down again, "How could I have killed my own husband." ”

"That benzene ......," Charlie continued to ask.

"The laboratory has a very strict chemical management system, and the amount and concentration of benzene storage are very carefully calculated. Even if I were a chemistry teacher, I couldn't just take the benzide out of the lab. With that, Brienne began to hide her face and weep.

Chiko angrily stood between Charlie and Britney, and used her body to block Officer Charlie's aggressive suspicions: "Mr. Officer, I hope you can understand that it is not a secret that Ms. Brienne and her husband can freely enter and exit the laboratory, and if she uses the benzene stored in the laboratory to attract attention too easily, only a fool would do that." ”

"Oh—I'm just asking. Charlie's flirtatious explanation made Chiko feel very unhappy, "So, Eric, how do you know that they have relatively easy access to benzene?" ”

Eric touched his nose and explained, "It's actually quite simple, I smell a faint smell of disinfectant on Ms. Brienne's body, and there is a thin strangulation mark on the wrist of her hands, probably because she always wears a pair of gloves. Imagine working with gloves and disinfectant on your body, and being either a medical teacher or a chemistry student at this university, and the medical school at Meate University is located in the central hospital of Lenkenshire, not in the university headquarters. And these traits are also present in Mr. Born, so it is likely that the work of the two of you will require long-term exposure to chemical agents. ”

Hearing Eric's reasoning, Ms. Brienne nodded incredulously: "That's right, my husband and I are in the same lab, and we both did chemistry experiments in the lab this morning. ”

Officer Charlie pursed his lips and snorted, "Actually, it's not that complicated, anyway, this information will appear in the transcript." ”

"Either way, Ms. Britney's suspicions are cleared. "Chiko is very unaccustomed to Officer Charlie's aggressive attitude towards Brienne, doesn't he know that this is a wife who has just lost his beloved?

"Not necessarily. Eric unwittingly withdrew the "steps" of the thousand sons.

"What!" Chiko glared at Eric angrily, why could this detective always go against her? Hearing Eric's "not necessarily", even Charlie showed a strange expression, and Brienne bit her lip even more, looking even more pitiful.

"First of all, Ms. Brienne, how does the lab manage highly toxic chemicals like benzide?" said Eric, who was very calm in response to Brienne's questioning.

"Teachers and students in the laboratory must declare and register in advance if they want to use these highly toxic chemical reagents, and there will be administrators to test these reagents every night. Brienne turned her head slightly, and continued to explain, seemingly reluctantly, "My husband used * powder this morning. ”

"Well, then, you are in the same laboratory, and even if you do not register, you may have come into contact with the powder of benzide at Mr. Beaune. Eric smiled slightly, "After all, you're husband and wife, not ordinary colleagues, right?"

"But, but, how did I poison me, waiter Walter, he ......" Miss Britney was momentarily unable to utter a complete sentence when asked by Eric.

The restaurant manager twisted the waiter Walter's back. It was then that Walter realized how important his testimony was to Ms. Britney.

"Yes, I can attest to this, I've been at this table. Walter swore an oath.

"Really, all the time?" Erik turned, pushing in Walter, "Are you sure you've been there from the time they sat down until Mr. Born died?"

"This, this ......"

As Eric approached him, Walter began to hesitate, and when Eric walked up to him, Walter said bitterly, "I just had two minutes in the middle to get a bottle of red wine." ”

"Can you be more exact? What time is it?" Officer Charlie thought he had seized his chance.

"This, I, I really can't remember. The muscles in Walter's face began to contort.

"I suppose, exactly, before Mr. Born and Ms. Brienne have their first bite of food after all the meals have been served, right?" Eric reached out and patted the waiter, Walter, on the shoulder.

"Yes. Walter nodded gratefully at Eric, "It was Ms. Brienne who added another bottle of wine, and at first Mr. Born disagreed, but Ms. Brienne insisted on drinking it, and finally Mr. Born agreed, so I went to the wine cellar to get the wine." ”

"But it's only about two minutes. Britney was like a cat that had been stepped on by its tail, and asked loudly, "May I ask Mr. Detective, how did I unknowingly poison my husband in 2 or two minutes, even if my husband didn't notice, but there is a camera in this restaurant, and the police will definitely call up the surveillance at that time, how can I guarantee that the police will not find out about my poisoning!"

Eric didn't immediately respond to Britney's question, he turned and paced back and forth in front of a messy table, muttering, "yes, how can you guarantee that?"

Officer Charlie said impatiently, "Hey, detective, who are you asking, you have a fart to let go, don't talk about it." ”

Eric ignored Charlie, he crouched down, picked up a fork from the ground, and used the fork to pick and choose in front of the pile of overturned meals, and said jokingly, "Charlie, you should really change your temper and calm down and look at these sumptuous dishes." ”

Charlie frowned and did not speak. On the contrary, it was Qianzi, she couldn't hold her breath anymore, grabbed Eric's shoulder, and said in a suppressed voice: "You'd better tell the reason immediately, otherwise ......"

Under the threat of a thousand sons, Eric's fork was twitched even more quickly. Suddenly, Eric's fork came to rest on a cucumber.

"This is it!" said Eric, with a hint of excitement in his voice.

"What is it?" all eyes were fixed on Eric's fork

"It's actually very simple, as long as you poison yourself in advance, even if there are ten cameras around you to shoot, no one will find out. ”
