Wang Xingrui shook her head. "I think the woman was the deceased's best friend, and the murderer was the deceased's boyfriend. Maybe it was a murder of passion! Of course, it could also be the best friend who found out her boyfriend was cheating on her and killed the deceased in a rage!"

"It's all possible," Lin Xuan'er said, not denying their opinion. She then opened the small refrigerator in the kitchen and found a birthday cake inside. But to her horror, there was a knife stuck in the cake. "I've made a new discovery."

She brought out the birthday cake and then pulled out a kitchen knife.

The bloodstains on it were exactly the same color as those on the deceased's body.

"This must be the murder weapon." Lin Xuan'er exhaled, "I suspect this is the crime scene."

Su Yin also discovered at this time that there was blood stain on the floor drain that had not been cleaned up.

"This is found in many detective novels," Wang Xingrui said seriously, "and many people tend to overlook it."

There was another line of words on the cake, which was obviously written specially: "Baby, happy birthday to you!"

"In other words," Wang Xingrui continued to sort out the plot, "Today is the deceased's birthday. The heroine was at home cutting watermelon, and someone came into the kitchen and killed her."

"Then the heroine must have known this person," Su Yin continued, analyzing, "otherwise, a normal person would resist if they saw a stranger, but the heroine didn't show any signs of resistance. I think she might have eaten watermelon with the murderer before she died."

After finishing speaking, Su Yin complained to herself: "I suddenly don't want to eat watermelon anymore!"

Everyone laughed, and Lin Xuaner ran to the living room, where there was also a trash can.

The trash can was clean, with only one invoice, from the cake shop, dated October 10th.

"This should be the deceased's birthday and also her death anniversary." Lin Xuan'er sighed, feeling sorry for this fictional character.

They still have two rooms to check, the bathroom and the study.

"Let's go to the bathroom first!" Su Yin suggested.

No one else had any objections, as they only found a few pieces of clothing there, one of which had a noticeable red mark on it.

"That can't be blood!" Tang Yue said, looking at the skirt.

However, Lin Xuan'er had already taken a sniff and said calmly, "That's watermelon juice."

"Obviously," Wang Xingrui laughed, "this dress is misleading, making us guess wrong about the first scene."

After all, they saw a piece of paper in the bedroom, asking them to write down who the murderer was, the crime scene and the reason for the murder.

I guess many people would think that the dark red mark on the skirt was the blood of the deceased when they first saw it.

"Let's go to the study!" Tang Yue said.

When I walked into the study, I saw a computer and a bookcase.

"These books on the bookshelf," Tang Yue took a look and was surprised: "They are all medical books."

"It seems that the deceased's husband must be a doctor." Wang Xingrui suddenly thought of something: "So after he killed the heroine, he dug out her heart? Not everyone can do that!"

"Eh..." Tang Yue covered her mouth: "Ruirui, stop talking. It's a bit disgusting."

They decisively changed the subject and rummaged through the bookshelf for a while, but found nothing except that the deceased's boyfriend was a doctor.

Lin Xuan'er and Su Yin were already sitting in front of the computer at this time. They felt that the final clue should be in this computer.

When it came to the power-on password, the two of them entered the heroine's birthday without any hesitation.

After all, they only found this string of numbers.

However, the password was wrong.

"You're stupid," Tang Yue said immediately, "Aren't computer passwords always six digits or more? I think it should be the heroine's initials plus her birthday!"

"What's the heroine's name?" Lin Xuan'er asked back.

Tang Yue stopped talking immediately.

At this time, Wang Xingrui lowered her head and found a mobile phone in the corner of the bookcase.

"This should be the deceased's phone," Wang Xingrui said, looking at its pink phone case. "Once we open her phone, we'll definitely know her name!"

However, the phone still needs to be unlocked.

They entered 1010 again, but it was still wrong.

"Oh my God!" Tang Yue was furious: "It can't be 1234!"

They tried it and were told that if they entered the password incorrectly five times, the phone would automatically lock.

"what to do?"

The four of them fell silent. Actually, they felt the murderer must be the deceased's boyfriend. As for the reason? A woman's intuition...

"Don't give up yet," Lin Xuan'er fell silent. "The time limit for the secret room is two hours, and only one hour has passed."
