The straw (hint 3)
Did you have a close look at the red envelope?

The victim's friend (solution)
On the straw, the first name "Emma" is written in morse code. A small piece of paper is hidden inside the red enveloppe. The first four dashes seem to match the 4 letters of the name "Emma". Her name must then have 5 letters (5 dashes), and can be found on the guest list. Only one guest has a first name starting with an "E":

The coded document (hint 2)
How can you use the holes and arrows in the coaster?
The coaster works as a tool to decode the series of letters on the other document. Put the coaster over the document, then turn it in the direction indicated by the arrows. If you write down the letters that appear in the holes of the coaster, you will get: "WITH MASK".

The entrance ticket (hint 1)
What symbol can you spot on the ticket? YOu may need to download an app on your phone to read it.

Le "code spécial" (hint 3)
Search online for the meaning of "rectangular transposition", for example on the website: http://practicalcryptography.com/ciphers/columnar-transposition-cipher/.
The web grid (hint 4)
What can be the cipher key? Listen carefully to the music clip.
The web grid (hint 5)
Isn't there a word in the music clip lyrics that stands out thanks to a weird sound? If necessary, identify this word by looking at the song's lyrics.
The web grid (hint 6)
You must now transpose each column of letters using the alphabetical order given by the key.
On the web page found by reading the QR code, an encrypted message can be found. To decode it, one must use the technique of "rectangular transposition" (the "special code" indicated on the ticket). In the song "By the Rivers of Babylon" (music clip), the horn sound covers the word "wicked": it is the keyword that must be used to decode the message. After ordering the letters of the key WICKED by alphabetical order(WICKED => 6.4.1.5.3.2), the columns are to be reordered in the same order.

What is the country of the flag found in the envelope? Can it help you identify Abaddon's future victim on the guest list?
On Emma Fornan's Facebook page, you will find a picture showing her friends who were at the Babylon party. The clues left by Abaddon allow to guess who his future victim is:
According to the picture caption, it is Matilda. On the guest list, several guests have a first name starting with the letter "M", but the Swedish flag helps you guess that it is "M. Eriksson": Matilda Eriksson is Abaddon's future victim.
