The murder of Venus

The smell of death

It took 10 years to find Venus body. No one had seen a case like this before. The body was still intact, she almost seemed alive, whoever killed her, sure did their best job at keeping her appearance at its best. Her eyes were wide open, her skin was as white as snow but her skin was flawless, her hair healthy as could be and her finger nails shaped neatly into an almond shape.

I look around the room, try to collect more information. There is a letter, hidden between the books on the shelf.

You've been invited to play my game.
Venus is my present to you and your first clue.

That is all that was written on there. Invited to play your game? That sounds nothing but trouble.
I inform my colleagues about it, they tell me not to to give in and play along, ignore it and just solve this case the regular way.
I agreed of course, but my gut tells me that somehow that won't be an option.

We searched the entire place but nothing else came up as evidence, everything was cleaned, the person who did this made sure to not leave any traces of them behind.

A ringtone, it keeps ringing and ringing. "Whoever's cellphone that is, can you please turn it off, this is a crime scene" The ringing continues... "Uhm sir..." John asks with a tremble in his voice. "Yes, what would like to tell me" I reply. "I think the ringing is c- c- coming from... inside the body of Venus..."

The ringing continues... I step closer towards Venus her body and put my ear towards her stomach. The ringing is indeed coming from inside of the body. The ringing continues for a minute and then it goes over to a message, a distorted voice speaks: let's play. You have 3 minutes to find the evidence I have left on Venus and after those three minutes, the body will explode and everyone who is still inside the building will die. Let the fun begin! Then the message ends.
The phone starts the count down.
