Complete story — includes the ending
Devout Christian father, Paul Devildis ( David Harbour ), is aroused by his daughter Katherine's ( Britt Robertson ) performance in a low-cut period costume during a school production of "Cyrano de Bergerac". Later that night, he murders his liberal sister-in-law and her husband with a hammer at their home. Eames and Goren are called to investigate the apparently random murders, but when the school drama teacher Vilma ( Karen Ziemba ) is also found killed with a hammer, they look for a connection through the school. They focus on Paul Devildis, and when his wife Mary ( Susan Misner ) is found shot dead in their home and he goes missing, they fear for the life of his daughter. The police track him down to a remote cabin and arrest him for the murders, then Goren engages him in a religious debate and convinces him to revealing the location of his daughter before she dies of exposure. The case is based loosely on the case of John List.
