Prominent Australian actress Carmen Duncan, here billed as "Stephanie Blackmore", guest stars as Christina Le Masters, onetime flame of police detective Rick Hunter (Fred Dryer). Christina seeks out Hunter's help after she stumbles upon the body of a murdered woman in a hotel room rented by her husband Kerry LeMasters. Finding a napkin marked with a purple circle at the scene of the crime, Hunter instantly recognizes this as the trademark of the infamous international assassin Tommy Largo--meaning that Christina's husband and the elusive Largo are one and the same! ~ Hal Erickson, Rovi
