You are the head of a mental hospital, taking over a patient who is a hand maniac, Riffer. Before, he had killed many people and only used beautiful hands to display. 

Not long at the hospital, Riffer used her beauty to seduce a nurse, then used her bones to make dolls and put her hands on display. 

You witnessed it all, then tied him up and locked him in the room. 

You kept questioning him but to no avail, he just stared at your hand, muttering 

"Your hand... is mine"
