Jessica (Angela Lansbury) and Seth (William Windom) are collecting research for her latest novel at the New Mexico site of an archeological dig. The scientists believe that they are about to uncover Coronado's fabled "City of Gold"; instead, they unearth a corpse of more recent vintage. The victim is an Indian guide (Randolph Mantooth) who was violently opposed to the excavation; the main suspect is a bit too obvious for Jessica's taste, so she does a little "digging" of her own. ~ Hal Erickson, Rovi
