Escape Extraordinary Jan Van Tilborg

In the 'old' workshop of the Volt Complex, Jan van Tilburg worked daily on repairs of TVs, radios and other consumer electronics. Jan was a genius and really knew no end, he was the first one at work, the last one to leave. He died a lonely death in the workshop in the winter of 1976.. the police think it was murder, the case still remains unresolved, due to strange circumstances and the silence of the management his workshop has been closed until the case is resolved.. Can you solve all the puzzles? Maybe then you'll able to open the door... escape is not possible without the use of your brains. Teamwork and collaboration are the key to freedom.
