In the lounge hall of the Ligon Annex, Yang Douxin, a business owner from Singapore, suddenly covered his neck in front of everyone, and died on the sofa with a hideous and painful face.

Just when everyone in the hall was shocked by this scene and stayed motionless, Bai Heqing calmly put on the white gloves that had been prepared, stepped forward and pressed the side of Yang Douxin's neck.

It's just a dead man, and he's seen a lot.

"There is no pulse, the person is dead."

Then, he looked at the blood slowly flowing from the corner of Yang Douxin's mouth, pinched his mouth hard, and leaned in to smell it gently.

"There is an almond-like taste in the mouth, possibly cyanide poisoning."

Letting go of his hand, Bai Heqing stood up, turned to look at the people behind him, and said:

"At present, Mr. Yang should have been poisoned and killed, and everyone in this hall was suspicious before, so before the police arrived, please don't leave this hall, so as not to increase your suspicion."

Mary immediately repeated his words in English, while Bai Heqing turned his head to look at the helpless old butler standing aside, and said:

"Steward Kurahashi, please go and call the police."

"Okay, okay, I got it! There's a radiophone at the end of the hallway, and I'll be right back! Kurahashi nodded and quickly turned to leave.

"How could this be, how could this ......"

On the opposite side of Yang Douxin, the retired Navy Lieutenant Clyde looked at his corpse in a daze, took two steps back, and muttered to himself and fell to the sofa with a shocked and frightened expression.

Of course, the expressions on the faces of everyone in the hall at this time were similar to him, but his reaction was the most prominent.

Bai Heqing glanced at him, and then set his eyes on the cup of coffee that had been knocked over by Yang Douxin before.

If he remembered correctly, when he and Mary first entered this hall, Yang Douxin was already holding this cup of coffee.

And Yang Douxin did drink this cup of coffee before he died of poisoning, so was it poisoned in the coffee?

"Did Mr. Yang brew this cup of coffee himself?" Picking up the coffee cup, the people of the Baihe Qing Dynasty asked.

"No, it's not, I brewed ......"

Kita-Uehiko, a university lecturer who is also one of the heirs of the inheritance, raised his hand and said with a somewhat flustered expression:

"Not only that, but I brewed the coffee of everyone in the hall...... But、But it's not me who poisons the coffee!

It's the coffee I brewed, and if I poison it, I'm sure I'll be the first to be suspected, how could I do such a thing?!

And the coffee is taken from the tray by everyone, and I take the last remaining cup! ”

Well, the logic is clear, and the key points are also stated.

Bai Heqing was very relieved to hear this, he hadn't met such a cooperative suspect for a long time, and it seemed that he should be able to solve the case quickly this time.

According to Kita-Kamihiko, although he brewed the coffee, the coffee that went to the hands of everyone was chosen by the people themselves, and he took the last remaining cup.

So unless there is a difference in each cup of coffee that can be chosen by a specific person to choose a specific cup of coffee, it is difficult to poison the coffee by poisoning it.

But unfortunately, Bai Heqing had just paid attention to observing, and the coffee cups used by everyone in the hall were all exactly the same set, and there was no difference in appearance.

Therefore, the murderer must have poisoned him through other methods.

"Humph! Who knows exactly how you poisoned it? ”

At this moment, Clyde, who was still a little distracted by Yang Douxin's death, seemed to have finally come back to his senses at this time, and he turned his head and looked at Kita-Imihiko with sharp and cold eyes.

"Mr. Clyde!" Questioned by Clyde like this, Kita-Uehiko shouted with some excitement: "Please don't doubt me for no reason!" What incentive do I have to do something like this?! ”

"Motivation? Of course, for the legacy left by Eijiro Tone. Clyde sneered and said, "There are already three heirs to that batch of inheritance, and now that Yang is dead, will it be my turn next?"

When we both die, you'll be able to claim this inheritance alone......"

"I've said it before! I wouldn't do such a thing for the sake of those legacies! ”

didn't care about the quarrel between the two, Bai Heqing on the side stretched out his hand and touched the cup of coffee that was knocked over by Yang Douxin and splashed on the carpet.

[The color is light, there should be something added to the coffee, is it milk...... Well? 】

Bending down, Bai Heqing picked up two small plastic bags from the carpet.

These two packaging bags are one long, look at the outside packaging, the long one is used to hold milk, and the square one is used to hold sugar.

It is estimated that when Yang Douxin spilled the coffee before he died, they also fell on the carpet.

[Ah, I see......]

"Ladies and gentlemen, apart from Mr. Yang, who else drank the coffee brewed by Mr. Kitaichima before?" A speculation suddenly flashed through his mind, and Bai Heqing asked.

"There are me, Young Master Hangsuke, Miss Mei Ling, and Mr. Kevin." The answer to Shirakawa Kiyoshi was Kita-Kamihiko, who was eager to clear his suspicions.

The young master of Hangsuke in his mouth refers to the second young master of the Tone family, Tone Hangsuke.

Miss Mei Ling and Mr. Kevin were the only two of the seven people in the hall who did not know Bai Heqing and Mary, the sturdy white male, and the East Asian woman in a purple cheongsam.

Five of the seven drank coffee, and the rest of Clyde and Tone's eldest young master, Tone, drank red wine.

"And who has added milk and sugar?" Bai Heqing gestured to the two plastic packaging bags in his hand and asked again.

"I added milk!" The first to answer was still Kita-Kamihiko.

"Like Kevin, I drank pure coffee and didn't add anything." The second young master, Tone Kosuke, opened his mouth and replied, and the sturdy man named Kevin nodded his head towards Shirakawa.

"I added both milk and sugar."

In the end, the cheongsam woman named Mei Ling was lying on the back of the sofa and said with a smile:

"The boss is the same as me, he also added milk and sugar, it's really amazing, obviously I and the boss added the same thing, why was only the boss poisoned in the end......

By the way, detective brother, like coffee, whether it is milk or sugar, we take it ourselves. ”

Saying this, Mei Ling also stretched out her finger and pointed to the coffee table placed against the wall not far away, and in the two plates on it, there were sealed and packaged milk and sugar stacked respectively.

The coffee is chosen by everyone themselves, the milk and sugar are uniformly sealed and packaged, and everyone takes it by themselves, and it is extremely difficult for the murderer to accurately poison and kill through these three things.

If you rule out the possibility that the murderer killed people randomly, that is, there must be something that Yang Douxin did and several others did not......

"Spoon."

Suddenly, Mary, who was standing next to Bai Heqing, touched her chin and spoke.
