"Hamster is the general term for hamster subfamily animals. There are seven genera and eighteen species in total. They are mainly distributed in Asia, and a few are distributed in Europe. Except for the small hamsters distributed in Central Asia, other types of hamsters have cheek pouches on both cheeks, starting from the molars. The side extends to the shoulder, which can be used for temporary storage or transporting food back to the cave for storage, hence the name hamster, also known as gill mouse, moving hamster. Hamster was first introduced by Japan for the study of teeth, and was later raised as a pet, and then extended to The whole world. The hamster raised in your residence is a Syrian hamster, also called a golden mouse."

Enomoto didn't directly answer Shimazaki Kawasuke's question, but said a long paragraph of explanation that seemed to be taken from an encyclopedia. In addition, Enomoto's speech was extremely fast, and everyone listened unconsciously The mouth gaped.

Although Junko has long been used to Enomoto speaking those jerky and difficult technical terms in long paragraphs, she was still a little surprised when she heard Enomoto say this. How did Enomoto-san remember this long paragraph? ?

Ashida Saori frowned and thought for a while, and suddenly had a flash of inspiration: "Could it be because of the property of hamsters that can store food?"

After hearing Saori Ashida's words, Junko was stunned immediately: "Could it be that the hamster's cheek pouch is used to put the key into the hamster's cheek pouch, and then find a way to transport the hamster to the drawer?"

"Think of a way? Think of a way? A hamster is not a human being. If you let it do something, it can do it?" Shimazaki Kawasuke said with a slight sarcasm.

"Maybe it's after training. Hamsters are used to finding food outside and bringing it back to the cave for storage through their cheek pouches. If the hamster thinks that the drawer is its own cave, it is possible for the hamster to go back to the drawer and spit out the key by itself. Come out?" For Shimazaki Kawasuke's sarcasm, Junko was obviously a little uncomfortable, but she ignored it, thought about it, and expressed her opinion.

"I don't think that's possible!" Enomoto vetoed.

Junko was taken aback: "Why?"

“黄金鼠的身长雄性一般是15到18厘米，雌性是15到20厘米，颊囊的长度一般是3到4厘米，而这间房间的钥匙长度是5厘米左右。”榎本解释道。

"That is to say, the key cannot be put in the cheek pouch?" Ashida Saori said.

Enomoto nodded.

"So, how do you use the hamster to put the key back in the drawer?"

"It's very simple, use alfalfa grass."

"Clover? How?"

"Just tie the key to the hamster's back with alfalfa."

"But if it is tied up, how does the key get into the drawer? Can it fall in by itself?" Ashida Saori still didn't understand.

Enomoto slowed down a bit, and said to Shimazaki Sosuke, "This is the cleverness of Mr. Sousuke's design. I think Mr. Sousuke started preparing for this method after he failed to steal the company's safe three months ago." Right? You keep feeding the hamster something, like laxatives or diet pills, or simply take away the hamster’s food secretly after Deacon Akagi feeds the hamster, reduce the hamster’s food intake, and let the hamster Slowly lose weight without being noticed..."

"Why do you want the hamster to lose weight?" Junko was a little puzzled.

"Because hamsters can only get in and out of the cage freely when they lose weight."

Junko and Ashida Saori thought about what they saw that day, the hamster got out of the cage by itself, and then got into the cage by itself, they both looked at each other subconsciously in a daze.

"Get in and out of the cage freely? Does this have something to do with the key?" This time it was Kawasuke Shimazaki who asked the question.

"Of course it has something to do with it. First, Mr. Zongjie fed the hamster laxatives or diet pills, or didn't give the hamster food at all. After the hamster lost weight, he began to secretly train the hamster so that it could get in and out of the cage by itself. Wait until the hamster knows how to After getting in and out of the cage on its own, the next round of training will be carried out so that it can follow a certain route back to the cage."

"A certain route?"

"Yes, it's similar to the route from the pipe hole of the air conditioner's internal and external units in this room to the desk. I checked your rooms and found that the layout of Mr. Zongsuke's room is very similar to that of this study, and they all face the east. There is a row of bookshelves on the wall, and in front of the bookshelves is a desk. I think Mr. Zongjie probably used this similar arrangement to train the hamster countless times in his room to get used to it from inside and outside the air conditioner. As for the training method, I think that as long as some food is placed in the cage to lure the hamster, and the hamster is likely to be hungry all the time, the training should not be too difficult."

"But, with this kind of training, you can put the key in the drawer?" Deacon Akagi was a little puzzled.

"That's right. Next, let me tell you in chronological order. First, one month before the incident, Mr. Zongsuke destroyed the air conditioner in the study and the anti-theft camera at the gate. On the morning of the incident, Mr. Zongsuke took advantage of Deacon Akagi and Kotani The maid didn't pay attention, sneaked into the kitchen, and mixed sleeping pills into the chestnut honey. So, after lunch, Mr. Keisuke, who ate the honey mousse cake made of chestnut honey, felt sleepy and went back to his room to sleep as the murderer expected..."

"But, Enomoto-san, didn't you say that, except for Deacon Akagi, it is impossible for others to predict that the dessert at noon that day will be a honey mousse cake." Junko couldn't help interrupting Enomoto.
