Even the niece of the dead man, when she is told by Donovan that there is a double indemnity clause for murder in his policy says that she does not want it. Lovely Barbara Britton plays Anita Weatherby the oldest daughter of the town's banker. She arrives on a bus in to and gets acquainted with Donovan,not knowing who he is or why he has come. She is very attracted to him but when she learns his assignment she becomes apprehensive that the town, her family, and feelings for Donovan will be negatively affected . Cover Up is relatively non violent. You never see the victim and the murder is really only speculation. It even has a hard to swallow morality ending. Nobody gets beat up,or threatened, and the pleas for Sam to just let the investigation go are more passive aggressive then raw anger.

Cover Upis a watchable film. with some dependable actors who give solid performances . A worthwhile way to pass an hour and 15 minutes
