The Quest for the Holy Grail

Thieves! Yes, but for the greater good!
For years you have been helping Professor Miller to gather a considerable collection of Leonardo The Holy Grail's work. Among these treasures there is what many believe to be the Holy Grail. The Professor has been paying you well over the years, but you feel that an item as important as the Holy Grail should be on display for everyone. While the Professor is away you have access to his home and knowledge of the security systems in it. Now is your chance, to steal the Holy Grail and get out! You have 70 minutes to do it!
