Yang Qiuchi asked Nangong Xiong to enter the warehouse and take out the replaced iron fence in the corner and put it on the ground. walked over and squatted down, beckoned to Kang Huai, Kang Huai also came over and squatted down, Yang Qiuchi pointed to the iron fence break on the iron frame: "My lord, please look, what does this break mean?" ”

Kang Huai carefully identified it, there were many thin saw marks in the front and back directions on the fracture, and he didn't see anything famous, so he shook his head.

"The saw mark on this fracture is from left to right," Yang Qiuchi pointed to the outside of the fracture again, "My lord, pay attention here, this last connection point is broken, that is to say, after sawing off the lower end, when the upper end of the saw was about to be sawed, the thief did not continue to saw, but broke it hard, which is enough to prove that the thief sawed from right to left." ”

Kang Huai looked at it carefully and nodded: "Yes, Lord Yang is right. ”

"But we are looking in the direction of the inside of the iron window, and from the inside, from right to left, but the thief came in from the outside, so from the outside of the window, the saw is from left to right."

Kang Huai lifted the window with difficulty, turned it over and looked at it, and nodded: "Yes, from left to right." ”

"If so, the person is left-handed."

"Yes," Kang Huai said excitedly, "only left-handers can do this." ”

"However, left-handers are very rare because they are often laughed at."

"Yes, I remember when I was a kid eating with chopsticks in my left hand, and I was beaten by my father." Kang Huai said with some embarrassment.

"Therefore, it is very likely that this person is not left-handed." Yang Qiuchi smiled.

"No, if you're using your right hand, you can't see from left to right."

"So, this man sawed from the inside!"

Yes! Kang Huai exclaimed in a low voice, thought about it, and his eyes lit up: "So you suspect that the guards and guards stole themselves and sawed off this fence from the inside?" ”

"That's right! The guards who are guarding the theft sawed from the inside, and stopped sawing the five railings when they were about to be sawn, so that if they didn't come up and look closely, they wouldn't find that the railings had been sawn and broken, and when they needed to, they would break it again. ”

"Makes sense!" Kang Huai said.

"After entering the Yunnan territory, I found that we have a lot of rain in winter, so these iron fractures are easy to corrode," Yang Qiuchi pointed to those fractures, "My lord, please see, these fractures are of different degrees of newness, some have rusted, and some are still relatively new, indicating that these fractures were not sawn at the same time." ”

Yang Qiuchi's analysis said that Kang Huai nodded again and again, but he thought about it, hesitated, and asked, "What if the thief is really left-handed?" ”

Yang Qiuchi nodded: "There is this possibility." Let's think about it from that perspective. There are two possibilities for thieves to come in from the outside, one is to come down from the roof and the other is to go up from below. ”

"The roof of the treasury is sloping, and the eaves stretch out very long, so it is very difficult for thieves to reach the windows if they want to come down from the roof, and it will be very troublesome to go up and down from the roof to avoid the night patrol, and at the same time, repeated up and down will leave traces of rope friction on the eaves, but I just noticed the eaves, and I found no traces of friction, so it can be ruled out that the thief sawed the windows from the roof."

"Then there was only one possibility left, grab the iron fence with your flying claws and climb up to saw. The adults said that they would inspect the area almost every half an hour on the night of the watch, and that it would take at least two hours to cut off the upper and lower sections of the five iron fences. Therefore, the thief needs to avoid the night patrol of the watch, that is to say, he can only saw for a while, the watchman comes, comes down to hide, and after the watchman is gone, he climbs up to saw, and so on many times, intermittently to saw. ”

"If that's the case, the thief should have left more footprints on the walls. But," Yang Qiuchi stood up, pointing to the few shallow shoe prints on the wall, "My lord, please see, judging from the movement route of the shoe prints left by stepping on the wall, it is obvious that they are only left up and down. ”

Kang Huai stepped forward to identify it carefully, and nodded again and again.

Yang Qiuchi pointed to the small air window again: "After the air window sawed five iron fences, it was just enough for one person to barely get in and out, and it was very difficult, if a fat person was a little heavier, I am afraid he would not be able to get in." Therefore, if the thief had stolen the silver from this window, it would have been impossible for him to carry it on his back, and the greatest possibility would have been to wrap the silver in one or several bags and throw it out, and then climb out on his own. ”

Yang Qiuchi pointed to the grass under the window and said, "Lord Kang, please look at this grass again," Yang Qiuchi jumped up on the spot and stomped on the ground with his heels, then got out of the way, pointed to the shallow footprints on the grass, and said: "Even if the two thousand taels of silver are divided into several bags, if they are thrown down from such a high air window, there will definitely be one or several pits left on the grass." ”

Kang Huai had already understood what Yang Qiuchi meant, squatted down and carefully inspected the grass under the air window, then stood up and shook his head: "The grass is very flat, there are no obvious pits. ”

"That's right! This further illustrates that it is not possible to steal the treasury silver from the gas window. ”

Hearing their analysis, the guard was already covered in chaff, and his face turned pale.

"Let's take a look inside the storeroom." Yang Qiuchi said to Kang Huai.

The two entered the warehouse, walked through a row of shelves with silver boxes, and came to the bottom of the air window, Yang Qiuchi pointed to the wall under the air window: "Have you noticed?" What marks are on this wall? ”

Kang Huai leaned in and took a closer look, and said, "I have also carefully observed before, there are two lines of footprints, which should be left by the thieves' upper and lower air windows." ”

"Except for these two rows of shoe prints?" Yang Qiuchi asked.

Kang Huai leaned in again to observe it carefully, took two steps back and looked at it, and shook his head: "There is no trace anymore." ”

"That's right!" Yang Qiuchi smiled and said, "Since the thief climbed in through the gas window and only left two lines of footprints, it means that the thief only went up and down once." However, he stole two thousand taels of silver, and if he wrapped it in a bag and carried it on his back and climbed up along the rope, the silver would be too heavy and very tiring, and it would be inconvenient to enter and exit. What would you do if it were you? ”

Kang Huai thought for a while and said, "Of course, put the silver on the ground, tie the bag of silver with a rope, and then climb up the air window first, turn it out and ride on it, drag the silver up, grab the remaining iron fence with one hand, and then throw the silver bag outside." ”

"That's right! These two thousand taels of silver are too heavy to wrap into one bag, and I am afraid that no fabric can withstand such a heavy weight, so the best way should be to weigh several bags of silver separately, prepare a few more ropes to tie them up, and pull them up separately, so that it is labor-saving and convenient. ”

Kang Huai nodded, Yang Qiuchi's analysis was very reasonable, but he didn't understand what Yang Qiuchi's analysis was trying to explain.

Yang Qiuchi pointed to the wall and said, "If this is the case, since these are saddle-shaped silver ingots with edges and corners, even if they are wrapped in the cloth, these silver wallets will leave drag marks on the wall." ”

Kang Huai suddenly realized: "There are no traces on the wall, which further shows that the silver was not stolen from the gas window at all, and these are all false impressions deliberately created by someone!" ”

Yang Qiuchi nodded: "If you want to steal the silver from this impregnable silver vault, if you don't steal it out of the air window, and there is no trace of digging holes and walls in the room, there is only one possibility, go out from the gate!" To deliberately forge these traces in the warehouse, outsiders can't do it, only the guards have this kind of opportunity! ”

"And the key is kept separately by two people, and it is impossible to open the silver vault without any one, and it will take a long time to cut the iron fence and falsify the scene, and it is impossible for one of the guards to hide from the other, so it is only possible for two guards to conspire to complete this conspiracy of the guards to steal themselves."

"Master Kang just said that the guards rotate once a day, and each time they have to count the treasury before they can hand over the shift, so they can only do it when they are on duty."

Yang Qiuchi walked back to the rotten window on the ground, looked at the sawn iron fences, picked one up, handed it to Kang Huai, and said, "There is blood on this iron railing, adults can smell it." ”

The iron railing was already rusty, and the blood had been covered by rust, so Kang Huai took a closer look and didn't find any blood on it, so he took it to his nose and smelled it, and sure enough, there was a faint smell of blood.

Yang Qiuchi said: "This should be when the guard faked the scene and broke the iron fence that was about to be sawn, a sharp break somewhere cut the palm of his hand, and the guard grabbed the iron railing with his injured hand, so the blood remained on it." I found that there was a lot of blood on the iron railing, and it was estimated that this person's wound should be relatively deep and would not heal in a short time, so I looked at their palms, and one of the guards did have a wound on the palm, so the suspect was identified. ”

After Yang Qiuchi finished speaking, he walked up to the two guards and asked, "How is it?" What else do you have to say? The two guards were already slumped to the ground.

Song Yun'er had been following behind and listening to them quietly, and finally couldn't help but praise at this moment: "Brother, you are so powerful, you can see it at a glance." ”

Yang Qiuchi smiled: "Didn't I say that any crime will leave traces, it depends on whether you can find it." ”

Kang Huaizan said: "Lord Yang said it well! He walked over and stared at the two guards, and asked hatefully, "Did you recruit yourself, or did the official punish you?" ”

The two knelt down and kowtowed: "We have recruited, my lord spares his life!" ”

Kang Huai asked, "What about the treasury silver?" Where are you hiding? ”
