"There are more people fishing in the big pond of Gujia, there are seven or eight people in the town alone, and there are even more people in Guli Village, when it rains, especially in spring and autumn, when the people in the village are idle, they will come to the big pond to fish, and I sometimes fish on the pier for a while."

"Who are the people who often fish on the north bank of the pond - the west side of the school? I'm talking about the people in the village. ”

"I'm one, Teacher Huo, and Principal Xu, there are just three of us in the school, and we all fish for a while after school in the afternoon. In the village, Peng Laosi - that is, Peng Datou's youngest brother, he works in the town health center, he is a dentist, and only on Sundays, he comes to fish. The one who came the most was Rong Gaotang. He likes to fish in the bend the most, which is where Director Wang often fishes. ”

"Where's the best place to catch fish?"

"That's right! The depth of the water there is just right, and the fish in the big pond come and go, all passing through the waist of the gourd. ”

In the end, Tang Erhu led the comrades to the place where he saw the "murderer" - let's set this person as the murderer.

The location is about fifty or sixty meters from the intersection of the west and north walls of the school. In the middle of a bush, there was a pile of excrement, and there were a dozen leaves above and next to it.

Tang Erhu walked sixty or seventy steps to the west, and then stopped: "When I saw him, he had already walked here. ”

The place Tang Erhu pointed to had no roads, only wild grass and leaves. According to common sense, the "murderer" should go the normal way.

"Tang Erhu, what direction are you looking at him?"

"All the way north."

"Did he see you?"

"He can't see me."

What Tang Erhu said was the truth, the bushes covered Tang Erhu's body, at that time, Tang Erhu was squatting on the ground, Ouyang Ping looked back at the bushes where Tang Erhu was, and he really couldn't see it.

Everyone followed the place pointed out by Tang Erhu to the south, and after walking more than 100 meters, there was a potato field, and the potato had already been finished, leaving only piles of withered potato vines.

The potato field is surrounded by a forest in the shape of a horseshoe, and the other side of the potato field, about a hundred meters away, is also a forest.

Ouyang Ping, Liu Dayu and Chen Jie walked into the potato field, and they wanted to see if there were any footprints.

"Uncle policeman, yesterday afternoon, a few old ladies were looking for potatoes in this field, and they dug up all the land." Tang Erhu said.

The three of them returned to the ridge and looked eastward, more than 100 meters away was the road where Tang Erhu went to school and left school, and the east side of the road was the school wall. Looking west, about two hundred meters away is a forest.

The murderer either crossed the potato field into the woods or followed the ridge west into the woods.

Everyone headed west, into the woods.

"The north is the village, Tang Erhu's family lives in the Zhuangzi in the north, and Peng Datou's family is in the west." Old Zhang Tou said.

"Is there Peng Datou's family in the west?" In Liu Dayu's impression, there seemed to be a few families there.

"There are three more families not far north of Peng Datou's house."

"What three families are they?"

"It was Peng Datou's three brothers, at first, Peng Datou lived with his brothers, and after he got married, he set up his own door and gave the original house to the three brothers."

Everyone followed behind Lao Zhangtou, all the way to the west, and after a while, they saw the house of Peng Datou's family.

The courtyard door of Peng Datou's house was locked, and when everyone walked in front of the door, a dog in the yard snorted a few low-key times.
