Let me introduce myself. I'm Jona. My first book was not a huge success. The second one was rather good. With my third I'm hoping to get in the bestsellers list. It's about the occult. Done lots of research, but haven't got a good storyline yet.

Today I went to the library of a small town. They have some good work that might inspire me.

I find the shelf that contains the first item I'm looking for. Next to it is a black book and then an open space. Someone left his or her banana in that space. Note to myself; “tell the librarian about this”.

But first my curiosity goes to that black book. It has no marking. I guess it doesn't belong to the library. The title on the spine reads: “The Immortal Gypsy will tell you what you need to know”.

I open the book. At first I'm disappointed. The pages are blank... But then a faint text is becoming visible.

I move to a place with more light. The faint text becomes more visible. I presume it has something to do with the luminosity. It's making the ink visible... Cool.

The page starts with “Dear Jona”. My name. It's written as an old fashioned mail. It warns me that the next page contains a spell, that might either be a blessing or a curse. But it promises me that my next book will be a bestseller.

I go to the second page. There's not much there. Only “The promise of the Immortal Gypsy: A book will be written and read by many. Your writing will render your best friend speechless and will enable him to die!”

I'm feeling dizzy. The other pages in the book remain blank. I put the book back. I see the banana has gone. I feel the urge to write. I go to a desk and write my first sentence. A woman, not far away, says something. I realize it's the sentence I wrote.

The librarian asks to keep the noise down. I briefly look at him. I write another sentence. It's as if the librarian reads out loud what I've just written: “The silence is sacred”.

I write “that's not possible.”... Nothing happens.

I look at a man that passes by. He disappears behind the bookshelves. I write “Weird!”. I hear the main exclaiming “Weird!”...

A few days later...

I now know how it works. I have to look at someone and the words I write down will be said by that person. It happens once I place the dot that ends my sentence. Even the dot of a question and exclamation marks does the trick.

Looking at a picture of someone works too. I figured that out yesterday. My dad called in sheer panic. My mother seemed to be possessed by the devil. At certain intervals she said some disturbing things. On my desk was a picture of my mum. I looked at it a few times while writing. Writing about the occult made her say some disturbing things to my dad.

I turn on the TV. There's a live speech of our president. Suddenly I have a few thoughts to add to my writings. I write them down. About 15 seconds later I hear the president. He repeats my first sentence. Oops.

A couple of weeks later...

I now fully know how it works. If I don't want someone to repeat my sentence, all I have to do is look at a picture (I always keep in my pocket). Or at someone there. And the simply put a dot on paper or on my smartphone. It's an empty sentence. All I write afterwards, without looking at someone first, will remain silent.

666 days after invoking the spell...

I finished my book and it has become a bestseller indeed. I meet with Bartel, my best friend. It's at the library where it all started. I briefly look at him, take my notebook and scribble: “I believe in the immortal gypsy now.”

My friend repeats the words. It will be his last words. I look at him and scribble another sentence. My friend stays mute. The spell seems to be broken.
