You find yourself in a blue room with very little scope for hidden objects. There are only four to collect and they are fairly easy to find.
There is a pen in the drawer beneath the telephone; a piece of paper under the seat cushion; a capsule in the tube on the wall; and a bank note behind the picture on the wall.
To get behind the picture, click on the top right corner to tilt it, then click on the top left corner to tilt it some more, then click on the bottom edge to pull it off the wall. A bank note will be revealed.
Use the paper and pen to write a message ("help me") and then place it in the capsule. Put the capsule in the tube and hit the red button.
A few seconds later the capsule will return and you will get the message back with a skull and crossbones drawn on it.
Now, the trick to escaping which you might work out eventually, but more likely you won't. You need to dial "help me" on the phone by pressing "4357*63".
The other end will ring then be answered and a voice will say "okay".
Now send the bank note up the tube and you will receive a key in return. The key will open the door and you are done.
Alternatively you can draw on the bank note first. It makes no difference, but y'know, it's something to do.
