After a successful examination of the office the players will have to solve sudoku, resolve puzzles and interpret charades. If they are able to arrive at the final code-phrase and act according to its specifications, the investigator will get a phone call and the kidnappers will declare, that they have released their captive, since they were only interested, if the collective is able to work as one for a common goal.
