Mr. Monk Joins a Cult

S6, E11: While out shopping, Natalie and Monk spot the parents of a recently murdered girl named Amanda Clark, and Monk begrudgingly takes the case -- before the Clarks even ask. Monk and Natalie visit the crime scene with Capt. Stottlemeyer and Lt. Disher and Monk speaks to Tom Donovan, the man who found Amanda Clark. Donovan says he saw Amanda being forced down and stabbed by a group of people -- one of whom was clearly the leader. When the killers spotted Donovan they took off in their silver van, leaving Amanda with ten stab wounds and a symbol of a sun carved into her chest. As he was driving Amanda to the hospital, Donovan heard her say, "He found me. Father found me." Then... she died.
