There is this no longer in use massive industrial chimney. It is easy to get down! You use it to get to the bottom floor. No one is around when you emerge covered in dust. You are standing in front of Gerald Ellon's office! A massive oaken door. His name plate is a thick bar of solid gold and his name is made of diamonds! The raw materials of this name plate must be worth about two hundred thousand dollars! It comes off easily! You stuff it in your pocket. You leave the way you came in. You chip out the diamonds and sell them one by one, the gold you melt down and sell in for fourteen hundred bucks! Good times. You have enough stolen money to live fat and lazy for a few really good years.
You could have doubled the easy time but that itch in the back of your mind craves the thrill of a steal.
