After Xiao Su left, Di Renjie did not leave the tea shop, still staring at the small courtyard, and even for lunch, he just asked the guys in the tea shop to buy a butter cake, and just made do with the tea.

But it's a pity that during the time that Di Renjie was staring, no one came out of the small courtyard. The only time the door was opened, and the little maid who had left before returned to the courtyard.

It wasn't until the courtyard gate was closed again that Xiao Su left the alley and entered the tea shop.

"Drink saliva first, don't be in a hurry." Seeing Xiao Su's sweat, Di Renjie first poured a bowl of tea for Xiao Su, and after he drank it all in one gulp, he said, "Went to Li's house?" ”

Xiao Su was stunned for a moment, nodded, and said, "The little maid didn't take a detour, and went to Li's house along the main road, but I don't know what he did when he went to Li's house." Fearing being recognized, I didn't get too close. ”

"It's okay, as long as you know that she went to the Li family, that's enough." After pondering for a moment, Di Renjie continued, "Inform Huiyue and let him choose a few shrewd and capable ones, two staring at this side, and two staring at the yamen. ”

Xiao Su answered, and was about to get up to leave, but was stopped by Di Renjie.

"Don't be busy, Li Siwei is busy keeping filial piety, even if there is any movement, it is impossible to move so quickly. You've just made a run, now might as well sit down and have lunch before you go back to them. ”

"Yes, join the army." Xiao Su responded, took the oil cake from Di Renjie's hand, and swallowed it in a few gulps.

"What, what else don't you understand?" Seeing that Xiao Su wanted to speak and stopped, Di Renjie said softly.

Xiao Su really didn't understand. He couldn't figure out how Di Renjie could guess that the little maid had gone to the Li family at once.

"Have you noticed that the little maid was carrying a food box when she went out?"

"It's as simple as that?"

"It's that simple. Why, don't understand? ”

For a while, Xiao Su really didn't figure it out. But immediately after, Di Renjie said a word, and Xiao Su understood.

"Think about it, what does a food box do?"

After thinking about it, Xiao Su suddenly said, "To put it this way, this little lady is still quite knowledgeable." ”

Di Renjie is a little close to his opinion, in his opinion, there are two possibilities for Xiao Niang to arrange the maid to deliver the food box at this time.

One is purely out of concern, worried that Li Siwei will not eat well at home, so he sent some food over.

The other is tempting. Let's see if the woman's attitude towards her will improve at such a time.

Of course, no matter what the little lady has in mind, she will definitely have a message in the food box, that is, there is someone snooping near the house today.

In fact, Di Renjie only guessed part of it.

The little lady did tell Li Siwei that there might be someone snooping near the house, but it was not mixed in the food box, but the little maid told Li Siwei directly.

Li Siwei was saddened by his mother's sudden death, and when he heard someone peeping near his private house, he was suddenly a little angry.

However, in front of the little maid, he didn't show it, but only comforted the little maid softly, saying that they had thought too much, and asked them not to worry, and he would arrange for someone to go over later and protect them nearby.

But after the little maid left, Li Siwei immediately called the eldest woman Zhao into the back room.

No one knew what the two of them said inside, but when the eldest woman came out of the back room, her cheeks were flushed, and her eyes were full of tears, as if she had been beaten......

Of course, Di Renjie didn't know what happened in the Li family.

At this time, he had already left the tea shop and went to Yizhuang alone.

When Di Renjie arrived, Song Mian was sleeping boredly under the big tree in front of Yizhuang. After being woken up by Di Renjie, Song Mian told Di Renjie everything he had found.

It can be said that this case is very clear.

The old lady was poisoned by arsenic, and the eldest lady Zhao just happened to buy arsenic.

But there is another thing in the whole thing that Di Renjie can't figure out, that is, why the eldest woman did it.

If you can't find the motive of the eldest woman, it is basically impossible to rely on arsenic alone, let alone make the eldest woman confess her guilt and surrender to the law, or even open a court trial.

Fortunately, there are still a few days to go, so Di Renjie is not too anxious.

Since it has been proved that it was the eldest woman who did it, the rest of the things will be much easier.

However, just when Di Renjie was just about to arrange for someone to inquire about the eldest woman's news, Xiao Su came back, and he also brought back a somewhat strange news......

After receiving Di Renjie's order, Huiyue immediately arranged four shrewd and capable people, two followed Xiao Su to Dashixiang, and two went to Yamen.

Xiao Su had just taken people to Dashi Alley when he found that the door of the house was open again.

This time, the person who came out became that Zhang's mother again. It just so happened that Xiao Su was about to return to the yamen, so he asked Huiyue's people to stay at the mouth of the alley and continue to star, while he followed Zhang's mother from a distance.

Zhang's mother was carrying a small bamboo basket, looking like she was going to buy vegetables.

However, this time, Zhang's mother did not go out to buy vegetables, but bought a basket of wild apricots. Seeing that Zhang's mother was struggling to leave with a basket of apricots, Xiao Su did not rush to catch up, but also went to buy a few apricots, and chatted with the vendor selling apricots by the way.

This chat, Xiao Su is even more strange.

Because, according to the peddler, Zhang's mother bought such a basket of apricots from him a few days ago......

After Di Renjie heard this, although he also felt a little strange, he couldn't say what the blame was.

However, Song Mian was stunned for a moment and asked, "That Zhang Ma, where is she from?" ”

Di Renjie was stunned for a moment, and said, "I said two words to her before, and the accent should be from the state." What's wrong? ”

"What about the other two?" Song Mian frowned and continued to ask.

Regarding this, Di Renjie and Xiao Su are not clear.

Di Renjie only knew that the origin of that little lady was brought back from Linxian by Li Siwei, and as for where it was, he really didn't know. And the origin of the little maid, a few people don't know anything.

"Important?" Seeing Song Mian frowning, Di Renjie couldn't help but ask.

Song Mian nodded and said, "Very important." ”。

Although it is very important, as for why it is important, Song Mian did not say it, only said that he asked where those people were, and he said why it was important.

For Song Mian to suddenly sell Guanzi at such a time, Di Renjie was still a little unhappy......
