Synopsis by Hal Erickson
Jose Ferrer guest stars in this episode--but not for long!--as a famed hypnotist known as The Amazing Cagliostro. As a publicity stunt, Cagliostro shepherds a group of six journalists behind locked doors, then hypnotizes them en masse. The act comes to an abrupt conclusion when Cagliostro is stabbed to death in full view of the journalists--who, being hypnotized, can remember nothing about the crime! Jessica (Angela Lansbury) of course figures that at least one person in the room was sufficiently conscious to commit the murder, and she's determined to find out which one.
