THE MISSING PROFESSOR

A team of researchers has been working on a formula for something highly secret. The matter is so confidential that, apart from Professor Dr. Rüdiger Bärenklau, no one knows what this formula can be used for. However, the work seems to have been successfully completed, because the professor has disappeared with the formula, presumably to sell it abroad for a lot of money. This formula must, of course, be recovered. Interpol, the international police organization, has already been asked for assistance. You now have one hour to determine the whereabouts of the professor and report it to Interpol. There are certainly enough clues in this laboratory, which you now have to find and piece together correctly. The professor’s assistant may be able to provide some useful information, so you should occasionally question him. Even though each puzzle you solve may raise new questions, the task can be accomplished with some detective work and, above all, teamwork.
