I picked the call.

"I left my phone, could you return it to me?" She screamed.

I headed towards the entrance, and let her in.
She walked straight to the storeroom.

But I never met her, how could she know my house, when did she left her phone?

And what for she went, when her phone is in my hand?

I followed her after she was out of my sight, "Who are you?"

But never got the answer.

Instead at the storeroom, she was lying dead with a smile, on the pile of clothes with blood all over.
