In the morning, because he got up very early, there were not many diners in the restaurant, so he entered the restaurant smoothly without queuing, and then handed the meal ticket in his hand to the waiter at the door, walked into the pick-up area and began to take the food.

He walked through the crowd, aimlessly selecting dishes, during which he did not contact the waiter, and no one took the initiative to provide him with utensils, towels and other supplies, and the restaurant staff kept a long distance from the tourists, and did not make contact.

The plate is taken randomly, the food is also taken randomly, there is no selectivity or special preference during this period, if the murderer chooses to poison the food then the risk is extremely high, this is almost an impossible task, not only will not ensure that the target will take the poisoned food, but also may accidentally injure other people, so the possibility of poisoning the food can be basically ruled out.

The possibility of poisoning the dishes is also very small. Since this is not a kneeling service, it would be very strange if someone came over and handed over the dishes.

But judging from the scene, the deceased did die of cyanide poisoning, so where is the place where the poisoning was applied?

Isn't it that this restaurant has made a mistake in the direction of its own investigation?

But the deceased was indeed poisoned in the restaurant, so how do you determine who entered the restaurant to listen...... Wait a minute!

A flash of light flashed through his mind, and Lin Yuhan noticed a detail.

The restaurant is only open to the top customers on the cruise ship, in order to maintain normal order and prevent others from mixing in the restaurant to eat, the buffet restaurant is admitted with a breakfast ticket. Each diner must provide a breakfast voucher for their room upon entry, which is sent with a cabin ticket, one per person per day.

Each breakfast voucher has a corresponding room number on it, so just look at these vouchers to know which guests have entered the restaurant, so it's much easier to investigate.

Then filter out the people who have intersections with the deceased, and the murderer can be locked.

Finally got some direction, Lin Yuhan became excited.

He came to the reception at the entrance of the restaurant and asked the waiter, "Hello, miss, do you still have breakfast coupons?" ”

"Sir, breakfast has been discontinued, there has been a murder here." The waiter replied politely.

"No, no, I'm referring to the used breakfast voucher." Lin Yuhan took out his documents, "I'm a detective and want to investigate the murder inside, can you show me the breakfast coupon I used this morning?" ”

"Oh, that's it, wait a minute!"

The waiter turned around and opened the desk drawer at the door, took out many receipts from it, and said: "We have a record of breakfast, don't worry, the management of the restaurant is very strict, and the receipts used by those who have entered are here." ”

"Thank you." Lin Yuhan picked up the breakfast coupons and checked them one by one.

There are no names in it, only room numbers. However, with the room number, you can find the user based on the ticket purchase history.

After reading it, Lin Yuhan had already memorized them. Breakfast began at five o'clock in the morning, and a total of 200 people were received, and the murderer was among these 200 people.

Sergeant Bell came over from a distance, probably in a melancholy mood, he began to hold a pipe in his mouth again, looked at Lin Yuhan and asked, "What is Mr. Detective doing?" ”

"Mark the room number." Lin Yuhan threw the breakfast coupon in his hand on the table.

"Look at this thing." Bell picked one up casually and said with a smile, "Come with me." ”

Sheriff Bell stretched out his hand to greet a police officer: "Come here, find out who the owners of these tickets are, and whether they have anything to do with the deceased." ”

Bell found a place in the dining room and sat down, holding his cane with both hands, resting his chin on the back of his hand, and staring out the window.

His mind began to wander.

He has been handling cases in the realm for many years and is about to retire. But before he was about to leave office, there were so many murders in a row, which seemed to be a joke played by God.

He thought that this trip to sea was a vacation.

It's troublesome enough, and there's a detective who gets in the way. Why is this young man surnamed Lin so nosy......

"Mr. Sheriff?" Lin Yuhan's voice came from the side, and Bell frowned.

"Ahem...... "Ahem just thought of a curse in his head when he heard this out-of-tune voice, Bell was very displeased, turned his head and asked, "What's the matter?" ”

"After the investigation is over, can you give me a copy of the list of users of the 200 breakfast coupons?" Lin Yuhan forced a smile, after all, he was asking for others, and he couldn't always keep a cold face.

However, he remained polite, polite without losing an embarrassed smile.

Flattery is not Lin Yuhan's character.

Bell squeezed his eyes, his facial muscles compressed together, he stared at Lin Yuhan and said in a helpless and angry tone: "Why are you so nosy? ”

"Because ......," Lin Yuhan thought for a while and replied, "I am a detective, and a detective must pursue justice and truth." Well, yes. ”

After saying this, he felt that he was suddenly much taller.

"Didn't you tell you not to meddle?" Sheriff Bell's mouth opened into an O-shape, and he almost scolded "It's your business".

However, he finally held back and said, "Do you know how Shinichi Kudo became Conan? Do you know how Conan died? Let me tell you, if it weren't for the halo of the protagonist, I'm afraid you wouldn't have watched this drama for ten years. Do you want to be Conan? ”

The threat of the red fruit.

"You can't say that about that...... How do you know I can't be the main character? Although Lin Yuhan didn't want to be the protagonist, he wanted to know the truth, so he could only reply to Bell with this sentence.

"Everyone wants to be the protagonist of this world, to live in the spotlight," Bell sighed heavily, slamming his pipe, and he looked out the window intently, continuing, "There is a price to pay to be the protagonist." First of all, do you have parents? ”

"This, yes, is still alive." Lin Yuhan didn't hide anything.

"Then why are you so the protagonist!" Bell stood suddenly, his eyes glaring.

Lin Yuhan took a step back, looked the short man up and down, and said lightly: "I want to create an era." We grew up under the protection of our parents, and now that we have grown up, we should be taller than them and be their protection, shouldn't we? We should have the opportunity to be grateful, not to squeeze the last shred of their value. ”

Bell didn't say anything, he didn't intend Lin Yuhan to discuss this topic, his mind seemed to be thinking about something, and he sat back on the chair in the dining room.

A police officer came over and said, "Report to the sheriff, the identity of the deceased has been clarified!" ”
