Two large doors come together, held closed by a simple latch.  Beyond the
doors is the home of a man held in high regards by those who choose
"alternative" careers.  It is said that he has trained the very best thieves
in the world.  The lack of a lock on the door brings a proverb to mind,
"Locks only protect you from honest people."  However, you worry that such
an experienced pilferer might have other means of discouraging unwanted
entry.
