The second door curtain was lifted - entering this door, inside was the bathroom, and out of it came a man about fifty years old, wearing only a short-sleeved shirt: "It's Director Gu!" Walk. Old Tang took out fifty yuan from the small door hole and stuffed it into Director Gu's pocket, "You are a rare guest, and I can't see you once a year to come to the 'guest often come', today is rare." ”

"No, it's because it's rare that I have to buy a bath chip."

After pushing each other for a while, Old Tang couldn't resist Director Gu - he had to give in.

After Director Gu took the bath chip, he followed Lao Tang into the second door and entered the No. 1 hall.

Old Tang settled everyone, muttered a few words to the running hall, and went to busy with his own affairs.

After a while, the runner put five cups of tea on the coffee table.

There is a wall clock on the wall, and the time is 6:35. The attendance rate of No. 1 has reached seven or eight, and everyone has greeted Director Gu. After that, they sat together in twos and threes and muttered quietly. From their eyes, they could guess that they were talking about the case at 157 Impermanence Lane.

Everyone enjoyed the look, undressed, took towels, and went out of Hall 1, opposite the bathroom. Comrades are busy working on cases all day long, and there is very little such leisure time.

The bathroom is divided into two parts, the outside is the shower area and the inside is the bath. There are three baths, the first is a slightly larger pool, the middle is a smaller pool, the innermost small pool is covered with wooden planks, there are some gaps between several wooden boards, some people with athlete's foot sit on the planks and burn their feet with towels, and a few elderly people lie on the planks to sleep, one of them snoring like thunder.

Three pools, the further inside, the higher the water temperature.

The whole bathroom was foggy.

The five people chose the first pool, just put their feet into the water, quickly lifted their feet up, because the water was too hot, but saw more than a dozen people lying in the pool, so, gritted their teeth, slowly went down to the water, first put the calves, and then enlarge the legs, and after slowly adapting, they submerged the whole body into the water, spit a few breaths, and the whole body became comfortable.

The body is completely relaxed, but the brain is still thinking about the case.

Left to the east slowly moved to Ouyang Ping's side.

Ouyang Ping sat up, he knew that there was a problem with Zuo Xiangdong: "Zuo Xiangdong, what do you want to say?" ”

"Captain, the first wall - it should be built at the back." Zuo Xiang Dong dialect only said one beginning.

"The purpose of building the first wall is obviously to hide the body," Liu Dayu moved to the front of Ouyang Ping and Zuo Xiangdong, he was also thinking about the case, "This wall is probably built by the murderer." Left to east, do you mean that? ”

"Yes, that's what I mean, the north side of the wing house is with doors and windows, and the tenants who live in it should know where the connection between the wall and the doors and windows is—a wall is at least as thick as a brick, and suddenly there is an extra wall, which should be visible, especially the people of Che Huating's family, who also lived at No. 157 for a while."

Ouyang Ping already knew what Zuo Xiangdong wanted to say next: "You want to find out when that wall was added, isn't that so?" ”

"Captain, you're thinking about this too! If we can figure out this question, we can know the approximate time when the deceased was killed, and then look for new clues based on this. ”
