Tonight,Alex arrived home much later than usual.
I provoked the police station yesterday by posting a 'murder notice' letter on an online platform.The content was:
"I am the protagonist of the 127 murder case.Let's meet at the east gate of Starry Sea Park at 8 o'clock tomorrow night!N"

(The first case was discovered on January 27th, so the named "127 murder case".)
After posting the message yesterday, it became the top trending topic within just five minutes, causing a brief server crash with a 404 error.
Of course, the comments section was filled with skepticism. After all, the Internet is anonymous, and IP addresses can easily be faked.
"This is obviously a fake.Anyone could post something like this."
"Isn't this disrupting the online order?This is taking a joke too far."
"Are the primary school students on vacation?Parents,please keep an eye on your kids."

...
"Could this be real?I'm stunned!"
"This serial killer is quite intriguing."
I was scrolling through the netizens' comments on my computer and couldn't help but burst out laughing.

These netizens are really something else.
The netizens were having a heated discussion,while I remained silent behind the scenes.
Only the police knew that this post was undoubtedly genuine..
Because on the left wrist of each of my victims,there would be a mark of"N"carved.
But the police had never released any relevant information.Only the relevant personnel within the police station knew about it.
Because the police feared copycat crimes,they didn't disclose this information.
About half an hour after the post went up,I received a call from Alex.
"Amanda,there's been a new development in the 127 case,so I won't be coming home tonight."
"Okay,then don't be too tired.I'll miss you."
"Okay,remember to lock the door."
"Okay,good night."
Shortly afterward,the doorbell of my house rang.
It was already quite late.I opened the door.
And I saw my seventh"victim".
