Lu Jinping was not in a hurry now, and said: "No problem, I can help the old lady find out the real murderer, and it will definitely not take more than an hour." - However, as you know, old lady, my family is now poor, and I am in debt, and I need money urgently. So I can help you solve this case, but I have to charge some fees. Of course, the fee I charge will not be very high, and you should be able to accept it. ”

Old Lady Gao frowned and said, "What? Do you still need to collect money to solve the case? ”

"Of course, you have to be paid for your work. If I were the arrester of the Yamen, or the criminal officer in charge of solving the case, then I would not dare to ask for money, because it was my job, but now I am just a doctor of medicine, I am not responsible for solving the case, solving the case is my extra labor, since the labor should be paid, why not? If you don't want to give up the money, you better ask another master, I don't want to bother with it. ”

Old lady Gao couldn't cry or laugh, but she couldn't refute his theory, thought about it and said, "Then how much do you want?" ”

"Not much, five hundred wen. Solving a case and collecting money mainly depends on the difficulty of the case. The higher the difficulty, the more money you collect. This case is easy to solve, so it only costs 500 yuan. Charge you 500 Wen, I promise to help you catch the murderer, and it is definitely the real murderer. In the future, your daughter will be safe, and you will no longer have to worry about the murderer poisoning. ”

These words made Mrs. Gao's heart move again, indeed, if you can buy her daughter's safety for 500 yuan, it is still worth a thousand dollars. Besides, 500 is really not much. Then he nodded and said, "Okay, if you solve this case and convince me, I will reward you with 500 yuan." ”

Lu Jinping smiled, if the idea of solving cases and making money makes sense, then he will see the hope of making a fortune in the future.

Lu Jinping said to Mrs. Gao: "Actually, I have already locked up the suspect, but now I need to look for evidence." He glanced at the maids and servants kneeling on the ground, as well as the three wives and concubines of the old lady Gao, "The chef and the cook lady stayed, and the rest of the people went to the courtyard, separated from each other, and no one was allowed to speak. Qingqing, you are in charge of supervision, whoever speaks, immediately arrest and send it to the yamen as a murderer! ”

Ye Qingqing hurriedly nodded in agreement.

These people saw that Old Lady Gao had authorized this doctor of medicine to solve this case, and of course no one dared to disobey his order, so they hurriedly got up, rushed out one by one, and went to the courtyard, seeing Ye Qingqing standing under the porch, staring at them fiercely, and they were all far away from each other, for fear of being suspected of whispering and being arrested as a suspect in the yamen.

There were still three chefs in the kitchen and a few cooks on the ground.

Lu Jinping didn't ask immediately, and said to the stout women: "You keep an eye on a few of them, don't let them talk." ”

Lu Jinping said to Mrs. Gao: "Old lady, please follow me to the kitchen." Then he said to the third aunt who was kneeling on the ground, "You also go to the kitchen with us, I have something to ask you." ”

The third aunt is now grateful to Lu Jinping, and she hurriedly agreed, got up and followed Lu Jinping and Mrs. Gao to the kitchen.

Lu Jinping entered the kitchen, first glanced at the kitchen, and asked the third aunt, "Where were you cooking just now?" ”

The third aunt pointed to a separate small stove in the corner of the kitchen and said, "Where is it, it is a small stove that specializes in cooking meals in the inner house." That's what I did just now. ”

"Do you often cook food in the kitchen?"

The third aunt nodded and said, "My daughter has a good taste, she likes to eat what I make, sometimes the chef is not satisfied with the food, I come to the kitchen to cook, so I often cook." ”

Lu Jinping walked to the small stove, looked up and down, left and right, and then asked, "When you were cooking just now, did anyone come to you?" Or help you stir-fry? Take something and give something or something? ”

The third aunt thought for a while and said, "No! When I was cooking, the big stove hadn't started cooking yet, and a few of the cooks who helped the kitchen were washing vegetables in the corner and didn't come. ”

"What about the three cooks?"

"I don't know where they are, not in the kitchen anyway."

"Have you ever left in the middle of cooking?"

The third aunt shook her head again and said, "No, I made a few dishes in one go, and then left, and I never left in between." ”

"Did you wash the meat and vegetables yourself?"

"No, the vegetables and meat to be used on the small stove are usually prepared by the chef in charge of the small stove first. I don't usually go to the kitchen, but I only go to the kitchen when my daughter wants to eat what I cook. Usually, the chef is in charge of the meals in the inner house. The other two cooks helped wash the vegetables or something, and the three of them were in charge. ”

"So, when you come to stir-fry, the cooks who want to stir-fry have already washed and prepared for you, right?"

"That's right."

"Has anyone else been in the kitchen?"

"I don't know exactly who has been here."

"Is there anyone in the kitchen on a regular basis?"

"Except for people when they cook three meals a day, there is generally no one."

Lu Jinping looked at a few jars of ingredients on the stove. Leaned up to take a closer look, especially the salt shaker, and nodded slowly.

When he saw that there were no small spoons in the jar, he asked the third aunt, "Don't these salt jars use spoons?" How do you add salt and condiments to a dish? ”

"It's all fingers, three fingers for three points, and five fingers for five points."

This is a method of traditional Chinese cooking, and it is often expressed in recipes. Lu Jinping has more research on cooking, so he also knows.

Then he walked around the stove, looking down, and suddenly, near the stove, in a small pile of garbage in the corner of the house, he saw a small ball of paper.

This pile of garbage is all kitchen waste such as vegetable leaves, and there is no other waste paper except for this paper ball.

Lu Jinping squatted down and looked at it, picked up the paper ball with two fingers, turned his head and said to Old Lady Gao: "Old lady, please hold this salt shaker with both hands, let's go to the main hall to talk-pay attention, the salt shaker is held steadily, don't move, don't shake it." ”

Old lady Gao was busy holding the salt shaker, and the third aunt wanted to help, but he glared at him fiercely, and quickly retracted her hand.

They came out of the kitchen and came to the courtyard, Lu Jinping asked the third aunt to wait in the courtyard, and then followed the old lady Gao into the main hall.

Lu Jinping put the paper ball on the coffee table, and asked Mrs. Gao to put the salt jar on it.

Lu Jinping instructed the senior executives waiting at the door to call in a few maids and mothers-in-law beside Mrs. Gao.

After these people came in, Lu Jinping said, "Raise your hands!" ”

Several people looked at each other, not knowing why. They all slowly raised their hands.

Lu Jinping walked past them and carefully examined their long nails, especially the cracks between their nails.

In ancient times, women's nails were relatively long, especially in large households. And the peasant women who need to keep short nails to do their work, because there were no special nail clippers in ancient times, they all use scissors to trim, so it is impossible to cut very iron, and a small piece of nails will be left.

When he walked in front of Mrs. Gao's personal maid Hanyu, he stopped, picked up her palm, carefully observed the gap between his fingernails, couldn't help sneering, stared at the maid Hanyu and said, "The person who poisoned you is you!" ”

"The slave is wronged!" Hanyu's face turned pale, and she knelt on the ground with a grunt, "The slave maid has been with the old lady all day, and the old lady can testify to this." The slave has never been to the kitchen, how can she poison it? ”

Lu Jinping sneered: "How do you know that the murderer poisoned the kitchen?" ”

Hanyu shuddered, and hurriedly said: "The slave maid is guessing, the slave maid really hasn't been to the kitchen, she really hasn't been poisoned, the slave and maid are wronged!" ”

"Wronged? You pour the arsenic into the salt jar and stir it with your fingers, because the color and particles of the arsenic are still different from the salt, and you are afraid that people will see through it, so you stir it with your fingers. Right? Lu Jinping turned to Old Lady Gao and said, "Old lady, look at the salt jar, is there any trace of agitation?" ”

Old lady Gao hurriedly stepped forward and lowered her head to take a closer look in the salt jar. This salt jar is relatively large, and it is a wide-mouth jar, so it can be seen really. Sure enough, there were scratches around the white salt in the jar, which proved that someone had stirred it, so he said, "Someone has indeed stirred!" ”

"Very good, please find another dog and a piece of meat for the old lady to test whether the salt in the salt shaker is poisonous!"
