The Butterfly in the Deadly Storm by Robert P. Fitton

Kathryn is plagued by reoccurring nightmares of a murder committed over forty years in the past by Conrad Ridder, a present day TV talk show guru. She returns to Plymouth, Massachusetts, where the Pilgrims landed- also the scene of the murders. There she meets Tucker, a truck driving cowboy from Arizona, who has dreamed the same dreams. When her free spirited friend Roz arrives in Plymouth they are all spirited back to 1958. Their mission: Confront the young talk show host and bring justice for the dead.
