Detective : [Detective tells Everett about Dr. Cotton death] We confirmed that he was most definitely poisoned. And we now know who did it. You might want to prepare yourself. It was his sons who did him. They both were studying ar Princeton and were slowly adding arsenic to their father's meals over time.
Dr. Everett Gallinger : You positive about this?
Detective : They confessed it. They were surprised that he died so quickly since as they sad, they had only been adding the arsenic a short while. Must have given him more then they realized. Not that I blame them. From what i gather, the old man was a nut. You know that crazy man pulled their teeth out of their head. His own children's teeth. Why the hell do you do something like that?
Dr. Everett Gallinger : He thought it would keep them sane. Have the boys been arrested?
Detective : They killed themselves before we could. So I guess Daddy's treatment didn't work out so great.
