The House-Sitter — Lee Karr

Lori Martin thought she would spend a quiet summer housesitting for Dr. Philip Brandon, a wealthy Denver physician. Without warning, the young school teacher is plunged into a terrifying plot that stretches from Denver's glittering heights to the steamy jungles of Vietnam, where her lover is missing in action...or is he?

Suddenly she is forced to impersonate the doctor's wife, playing a part in a treacherous game that includes a P.O.W., an absent wife, a pair of oriental children, and a mysterious smuggled cargo, adding up to a deadly mix of mistaken identities, international intrigue -- and unexpected romance.
