Exit Room Helsinki: Holiday in the Caribbean

It is the last day of your dream holiday in the Caribbean. You just ordered a taxi that will pick you up within 66 minutes to bring you to the airport. Under no circumstances you can may miss your flight. Your visa will expire today. Your luggage is still unpacked. On the way back to your luxury hotel suite, you somehow mix up the room numbers and end up in somebody else’s suite. Some strange notes and sketches gain your attention. The room’s owner obviously was trying to find a German submarine that sank during World War II somewhere offshore, somewhere really close to this hotel. According to his notes the submarine was loaded with tons of gold and diamonds. Is this story true? Will you find out about the submarine and the treasure? Anyway, you have to hurry. You got only 66 minutes left and the owner of the hotel suite could come back any time.
