On the wall behind the chair, there was originally a landscape map hanging upright, but at this time, the landscape map had moved its position for no reason, and the whole was moved to the left, and a space as large as the landscape map on the exposed wall was exposed in front of Mo Chen and others.

Mo Chen stretched out his hand and touched it in the hidden space, a few gold bars and some papers were placed in it, Mo Chen took out those papers and looked at them carefully, and vaguely saw some handwriting, which said XX Qianzhuang, it turned out to be some silver tickets.

"She's here to steal money? Unfortunately, he was found by the owner's family, brutally killed, and his body was hidden here? Wang Lei analyzed.

Mo Chen touched the female corpse, the female corpse was dressed simply, although it was a little stronger than Sun Ma's coarse linen clothes, but judging from the feel of the clothing, it should probably be the identity of a maid.

"Even if she came to steal something and was caught by the master's family, the Qian family could choose to send it to the official, or wait for the family law, there is no need to hide the body." Mo Chen said.

Wang Lei was very surprised when he said about the family law, "What are you kidding, it's not that there is no royal law, how can you decide a person's life and death casually!" ”

"Have you forgotten what the shopkeeper said when he asked us?" Mo Chen continued, "I signed a deed of sale with the master's family, and my life is in the master's family. ”

Zhang Zili added, "Even if the bitter master's family comes to ask for an explanation, it is just to ask for some silver to go back, and the officials and gentry collude, if the trouble continues, the bitter master's family will not be able to get any benefits, so they can only give up." ”

Wang Lei still couldn't understand this era, how could people's thoughts be so sick, he sighed secretly and stopped making a sound. Zhang Zili asked, "What do you think about this, sir?" ”

"Since I know that there is a secret compartment in the study, it must be done by the Qian family, maybe this girl spied on the secrets of the master's family and was killed, and for a while, the murderer could not place the body, so he had to hide here temporarily." Mo Chen said.

"Sir has already guessed who the murderer is?" Zhang Zili suddenly came to his senses, and Mo Chen hesitated a little, "Mrs. Qian!" However, it is only speculation, and it is not certain for the time being. ”

"Dignified mother, why can't you get along with a little girl." Zhang Zili muttered to himself.

Mo Chen touched the corpse, and from the stiffness of the corpse, it should not be long before the time of death, but when Mo Chen approached the corpse, he vaguely smelled some sour rot, because there was no light, he could not see the condition on the skin of the corpse clearly, but from the taste, Mo Chen guessed that she should die before her grandmother. Time cannot be determined, the candidate for the murderer has naturally expanded a little, it can be the so-called before the death of Master Qian, after all, this is his study, if he was alive by this maid snooped on the secret, so the murder and hiding the corpse are also said here in the past. However, thinking of Zheng Yi saying that the strange thing that someone disappeared only started after the second aunt was martyred with the master, Mo Chen felt that the suspicion of the old man was not great. As for the killer in a dispute between the subordinates due to the uneven distribution of spoils, there should be no need to deliberately hide the corpse in the master's study, after a long time, the corpse will stink sooner or later, this is not waiting to be discovered by the master's family! So compared to the above, Mo Chen felt that the suspicion of the Qian family's housewife was relatively big, the master had passed away, and generally the subordinates came to the study to clean up when they left the master's house, and no one would deliberately enter the study the rest of the time, but the housewife was different, the Qian family was up and down her decision, and no one doubted where she was going.

"What are you going to do with her?" Zhang Zili pushed down his glasses, Mo Chen thought for a while and said, "Return to the original position, lest the murderer find out that someone has broken in here." ”

Mo Chen and Zhang Zili worked together to carry the corpse back into the dark grid, Wang Lei hid far away, he stayed in a room with a dead corpse, which already made him feel unlucky, not to mention that he had to touch the hard body. It's very easy to put the body back, but the landscape painting in front of it can't be moved back.

After carefully looking at the clues of the landscape painting, Mo Chen saw that the back of the original landscape painting was connected to a wall similar to a cabinet door, and no one would find the existence of this secret door if he didn't look carefully. Mo Chen tugged on the secret door a little harder, and found that it seemed to be fixed in the wall, it seemed that there should be an internal mechanism here, and if it was not activated, the secret door could not be moved by external forces.

"What the hell did you just touch?" Mo Chen asked.

Wang Lei was originally playing with it unintentionally on the desk, and he was frightened by the sudden ejection of the dead body, so the memory of the other party was naturally not very clear. He prevaricated and recalled: "I seem to have touched these pen, ink, paper, and inkstones. ”

Mo Chen stared at the furnishings on the desk carefully, the inkstone seemed to have been fixed on the desktop and could not be moved, Mo Chen tentatively twisted the inkstone in place, Zhang Zili stared at the inkstone with wide eyes, waiting to see that after the inkstone twisted, the mechanism of the secret door would be triggered. Mo Chen sighed and let go of the inkstone, it seemed that it was simply fixed, and it was not the secret door mechanism he guessed, Zhang Zili was also a little disappointed.

Zhang Zili learned from Mo Chen's appearance, and moved the things on the desktop one by one, but they were all things in the study, and there was no mysterious mechanism.

Mo Chen squatted down, got under the desk, his hand lightly tapped under the tabletop, and on the inside of the table leg that rushed out, Mo Chen touched the small wooden block that seemed to be supporting inside, and shook slightly as Mo Chen's fingers strained it. Mo Chen got up in his heart, and puzzledly drilled out the position corresponding to the corner of the table from under the table, and on the table was a fixed pen holder.

"Where's the brush you took out to play with?" Mo Chen asked.

Wang Lei took out a brush from his trouser pocket and handed it to Mo Chen, and said embarrassedly, "Here!" He was afraid that Mo Chen would misunderstand, so he hurriedly explained that he was just scared, so he put the brush in his pocket, but he didn't deliberately want to take the brush away.

Mo Chen was not interested in whether he was going to steal the brush, the tip of the brush was not stained with ink, and Wang Lei was just playing, and he didn't really want to draw on the paper. Mo Chen lifted the brush and drew in the palm of his hand, the original soft bristle brush head was actually hard, Mo Chen inserted the brush back into the pen holder vertically, and with a faint sound, the secret door that fixed the landscape painting slowly closed, returning to the original appearance when they came in.

Mo Chen and the three of them stayed in the study for a while, but apart from the roster that recorded everyone in the Qian family, they didn't gain anything else.

"Let's go! Check out the other rooms! Mo Chen said, gently closed the window where they jumped in, and glanced at the room roughly, fortunately this place did not change because of their visit.

Zhang Zili took off his coat and threw it on the ground, let Mo Chen and Wang Lei stand at the door first, and carefully wiped the ground in their range of activities with his coat. Mo Chen approvingly, "I didn't expect that you are quite careful." ”

"Leave these footprints, you don't need to check whether anyone has touched the book, and you find that someone has broken in, let's be careful!" Zhang Zili said.
