Bloody Novel(C)

I was relaxing on the porch of the house after completing my homework my parents gave me before going to Uncle Wiko's house. Aunt Nur came with a cup of hot coffee and put it next to me.
"Here, Non, the coffee," said Aunt Nur.
I was shocked. Since when do I like coffee and when do I order it? Not yet to protest, a postman stopped in front of my porch. Pressing the bell and forcing me to get up and approach him. When I got there, the postman disappeared without a trace. I came back in shock. I looked around but I couldn't find anything.

Disappointingly, I set foot in the yard. And I found a plate of fried rice on the table on the porch.
"It looks like Aunt Nur is going." I said and went inside, to the second floor where my room is. I opened the door of the room but something strange happened, the door was locked! I was shocked again. It was clear this morning that the door was open. Then I went to the kitchen to get a backup key. I smelled fresh and slightly sweet when I entered the kitchen. I thought Aunt Nur just cut fish or meat and forgot to clean the leftovers. Yeah ... I don't think about it anymore. I took the back-up lock of the room hanging on the wall next to the fridge.
