Temporarily shaken by the fact that Laura Murdock Stockbridge's coffin is empty, Joe (Joel Crothers) and Dr. Guthrie (John Lasell) pry open the coffin of Laura Murdock Radcliffe, only to find it empty as well. Still, sufficient evidence exists to connect the two missing corpses with the present Laura Murdock, the estranged wife of Roger Collins. This episode first aired on March 3, 1967. ~ Hal Erickson, Rovi
