The holes and soles models that Luo Fei and Gu Yunfei found on the curtains of Yang Biao's bedroom helped them sort out their assumptions, and they were in a happy mood, but it was a great test to find the real murderer.

They left the Qingtan apartment, passed by the Jingjing flower shop, and the owner of the flower shop who delivered potted plants to Kuanna, stopped them, and accosted them, apparently wanting to inquire about the tragedy of the Qingtan apartment. He first looked at them with a smile and looked at them for a while, then stretched out his index fingers with both hands, made a gesture for the two of them together, and said with relief: "It's good, a man's rose chases the police girl he loves - in and out of the right pair." ”

Gu Yunfei defended: "Florist owner, you sell flowers well, don't guess, I won't be deceived by him because of a rose, and he is in and out of pairs, he is helping ......."

Luo Fei pulled her into his arms, covered her mouth, and said to the flower shop owner, "Yes...... Yes, we're just in pairs. ”

The owner of the flower shop muttered, "I'll just say, such a handsome young man will definitely please the girl." ”

When the owner of the flower shop was about to ask about the murder in Qingtan Apartment, a faltering silver-haired grandmother walked into the flower shop and walked straight to a pot of budding narcissus, and when she was about to ask the shopkeeper about the price, Gu Yunfei was wearing a police uniform, turned around and walked towards her, pulled her to the road in front of Qingtan Apartment, and asked in a low voice: "Girl, I see that you are wearing a police uniform, you should be here to investigate the murder case in Qingtan Apartment, right?" ”

Gu Yunfei nodded and said, "Yes!" Mother-in-law. ”

The silver-haired grandmother said, "I've been wanting to find you police for a long time - to reveal something to you. I've always had bad legs, and it's very inconvenient to go to your police station. ”

Gu Yunfei said: "Grandma, your legs are inconvenient, you can call 110 and tell the police directly." ”

The silver-haired grandmother shook her head and said, "This can't be done, I have to say in person in front of the police officer in charge of this case, girl, you should be the police officer in charge of this case?" ”

Gu Yunfei said: "Yes, grandma, I am in charge of this case." ”

The silver-haired grandmother said: "I am a resident of the peony garden next door to the Qingtan apartment, I am seventy-five years old, my wife left early, the two children have their own families, and I have bought a house to live in, and I live alone in the old house of the peony garden." I don't know if it's because I'm old and I always have insomnia at night. As long as I have insomnia, no matter how late it is, I will go out for a walk, there is no one to talk to at home, and I can come out to see the nightlife of young people, which can be regarded as relieving my boredom......"

Gu Yunfei said: "Grandma, you are so old, your children should be by your side more to accompany you!." ”

The silver-haired grandmother said unhappily: "Girl, I haven't finished my words yet, so don't interrupt me, it's rude." ”

Gu Yunfei nodded embarrassedly, and listened intently to Grandma continue to speak.

"On the night of the murder, around half past one in the morning, I came out of insomnia and was going to go to the nearby Luolin Night Market, where the young people were about the same age as my grandson......

Gu Yunfei saw that she was wordy for so long, and she hadn't said what she wanted to hear, so she couldn't help but be a little anxious, but it was not easy to urge, so she had to be patient and listen to her.

"To get to the Luolin Night Market – I have to go through the road in front of the Cheongdam apartment. As I pass this road, girl, guess what I see? ”
