"I ...... It arrived the day before yesterday. ”

The man pulled out a train ticket stub from his pocket. Yan Ruyu took a look, and sure enough, he arrived in Jingbei City the afternoon before yesterday.

"And what did you do with both?"

"Looking for their mother and son, the mother-in-law answered my call, but she refused to see me, and said something for her to consider.

Damn, Lao Tzu has dozens of dollars on me, and I don't have enough to live, so I slept on a park bench for two nights, and she played a temper with me......"

"And how did you find here?"

"I vaguely remember knowing that her sister's family opened a shop near here, selling mutton noodle soup, so I inquired all the way to find it, and I happened to walk here this morning, and I saw a lot of people around, just to come and have a good time, who would want to ......" The man lowered his head and wiped his eyes, "Why is my baby gone?" ”

He didn't have any logic in his speech, a hammer in the east and a stick in the west, but fortunately, Yan Ruyu was experienced and had a clear way of thinking, and he was not led by his nose.

Yan Ruyu continued to ask, "Which park did you spend the night in these two days?" Can someone see that you can prove it for you? ”

"There's a homeless man, I've talked to him for a while, and I don't know if he's still there."

Xiaobai volunteered: "I'll take him to confirm his whereabouts first!" ”

"Done!" Yan Ruyu nodded, and said to Minghui: "Let's start visiting the periphery, focus on people who have conflicts with the proprietress's family, pay attention to debt transactions, as well as nearby restaurants and peers, I think her business is good." ”

"Understood! Isn't there a saying that only between peers is naked hatred. Feel relieved! I'll keep an eye out! ”

After solving these extraneous matters, Yan Ruyu returned to the back kitchen again, but saw Wu Cuo poking his head out of the skylight, not knowing what he was looking at.

"Did you find anything?" Yan Ruyu asked.

"Don't say it, footprints! Fresh footprints! ”

As soon as he heard this, Yan Ruyu also came to his senses, and hurriedly asked, "What kind of footprints?" ”

"Man, the shoe size should be 40, judging by the sole pattern, he is wearing a pair of leather shoes that are badly worn."

Yan Ruyu shook his head, "It's not the child's father, I just saw it, he is wearing cloth shoes, and the decoding is at least at No. 42." ”

In this way, it should be an outsider who left the shoe prints, not the cooks and waiters who live in the backyard. Because if they enter the back kitchen, they can go directly to the back door instead of climbing the wall and climbing the skylight. ”

"That's right." Wu Cuo simply climbed onto the roof from the skylight and followed the footprints on the roof.

This is a row of one-storey façade houses, the façade is uniformly decorated in an antique style, and the roofs are connected, which is 50 meters long.

The footprints stretched to the end of the roof, and traces of climbing were found on the side walls of the house.

Yan Ruyu also climbed onto the roof, following Wu Cuo's pace.

Looking at the side wall that left traces of climbing, Wu Cuo said, "It seems that someone has climbed up from here." ”

"But why is there only a row of footprints when you go?" Yan Ruyu asked, "Someone climbed up from here, walked to the skylight, climbed down the skylight, and entered the mutton noodle soup shop, but did not return along the road, how did the murderer get out?" ”

Wu Cuo frowned and thought for a while, "But...... There are no traces of climbing at the skylight, could it be ...... This person on the roof is ...... with this case It doesn't matter at all, it's just that someone is bored and scared of the roof......"

"Impossible! You have also seen the footprints along the way, and there was no hesitation in the middle, this person's goal is very clear, that is, the skylight of Shen Ji mutton noodle soup shop.

Moreover, if you go to the room casually, you always have to leave footprints on the return trip, but these footprints come to an abrupt end when they reach the skylight of Shen Kee Mutton Noodles Soup Shop, and people must have entered the skylight. ”

Yan Ruyu returned to the back kitchen the same way, while Wu Cuo stayed on the roof to take pictures and collect evidence.

As soon as he returned to the back kitchen, Yan Ruyu took a closer look at the plates and jars on the stove table. After reading it, he pointed to a few of the large enamel jars and asked Master Wu, "These oily things are usually placed here?" ”

"That's right, the clear oil and spicy oil have been here all along. And ......" Master Wu hesitated for a moment and pointed to the bottom of the desk, "and that inside, it's also full of oil, and it's usually fried oil cakes...... That's the oil. ”

Yan Ruyu looked at the white plastic bucket under the table.

I didn't see the contents of the bucket, but I asked about a bad smell first.

Yan Ruyu dragged the white bucket out a little, and the smell became stronger. It's like something fried and then sour, with a burnt and rancid smell.

"It's ...... Damn it! Gutter oil! Yan Ruyu scolded a rare foul word.

He was accustomed to the smell of rotting corpses, but at this time he was very sick to his stomach, and he had to resist the feeling of retching.

"You guys!" He pointed to the master's nose and wanted to scold, but he held back, and finally just sighed.

Yan Ruyu looked the white oil drum up and down. The oil drum is cylindrical, about one meter high, and has a radius of seventy or eighty centimeters.

There is a circular opening on the top with a radius of about 30 centimeters, and there is no lid.

The barrels around the round mouth have a lot of dry oil spots, which seem to have been dripped when the oil was scooped outward.

There was also a large mark left by the spilled oil on one side.

Yan Ruyu carefully looked at the trace, and then touched it, and found that the oil that had been spilled had not yet completely solidified.

"So it seems that leaving shoe prints is the right time to do so

This is a row of one-storey façade houses, the façade is uniformly decorated in an antique style, and the roofs are connected, which is 50 meters long.

The footprints stretched to the end of the roof, and traces of climbing were found on the side walls of the house.

Yan Ruyu also climbed onto the roof, following Wu Cuo's pace.

"But why is there only a row of footprints when you go?" Yan Ruyu asked, "Someone climbed up from here, walked to the skylight, climbed down the skylight, and entered the mutton noodle soup shop, but did not return along the road, how did the murderer get out?" ”

Yan Ruyu returned to the back kitchen the same way, while Wu Cuo stayed on the roof to take pictures and collect evidence.

As soon as he returned to the back kitchen, Yan Ruyu took a look at it first
