The vault is hidden behind the painting. Below is a note with two flags: Sweden & Portugal.
The second part of the note is inside the cigar box with flags of Canada, Brazil and Australia.
The world map on the wall shows the numbers 2 8 7 4 1 for these countries – and that’s the code to open the vault.
The first letter inside the typewriter reads:
“I am a man of science,
No-one could deny that.
With glasses but no facial hair,
Say, have you met my cat?”
In second drawer on the right you find:
“No noblewoman, I
You’ll find me in the camp.
With my bonnet and my ribbon,
I’m the lady with the lamp.
I am a great researcher,
I won the Nobel Prize,
With a brush moustache (but not a beard!)
Have I saved countless lives.”
Inside the vault you’ll see a doodle of the antler on the wall top left, which points downwards.
There are also nine banknotes inside. The descriptions of the persons on the banknotes gives the code 5 8 3 – that’s the code of the padlock of the drawer on the left hand side of the desk. Inside is a key to the locked part of the shelf. There you find the UV-torchlight and a doodle of the antler top-center on the wall, pointing to the left.
Using the UV-torchlight you’ll see something below the carpet. The top-right antler points to the left.
Inside the left drawer you see a doodle of the wide antler (bottom on the wall), which points to the right.Turn all four antlers to the correct direction and you made it!
