The Da Vinci Room

Dr John Albright has studied the workings of Da Vinci in great detail. He has amassed a considerable collection over the years, including what many believe to be the Holy Grail. Having gained his trust by helping him "acquire" items over the years, you have access to areas of his home and knowledge of his security that no-one else does. You've been paid well for your services over the years, but you've always felt that an item of the importance of the Holy Grail should be on display for everyone. The professor is away and now is your chance. Get in the room, grab the grail and get out. It should be easy!
