Spellbound

S6, E19: During a "reading" with two young women, a psychic begins to see visions of her own murder instead of information pertaining to her clients. When she is later found dead in her occult shop, it is up to the team to determine her true cause of death. While Greg suspects greater forces may be responsible for the woman's demise, Grissom steadfastly maintains that science will always crack the case in the end.
