One of the hardest keys to get had belonged to an old Faery Queen who had 
seen through every trick that Nell could think up and fought off every assault.

Queen and told her the sad story of Harv locked up in
the Dark Castle. The Queen had fed Nell a nice bowl of chicken soup and handed 
over the key with a smile.
