The Riddle Maker

In the long history of the T.E.A. - the Think Escape Agency - there is only one case that has never been solved and that still leaves the agents puzzled to this day. Sixty years ago, one of the agency's founding members, Agent Magni, disappeared when he was about to solve the mentioned case. He was on the trail of the so-called "Puzzle Maker", one of the greatest adversaries the T.E.A. has ever faced. Nobody could access Magni's files and findings - until now! His security system, which is still state-of-the-art even today, has to perform a security update after all these years, which opens up a 60-minute window for us to finally inspect his office and all documents and to finally be able to close the case. Can you still solve the almost forgotten case?
