Female on the beach (1955)

Lynn Markham moves into her late husband's beach house the morning after former tenant Eloise Crandall fell from the cliff. To her annoyance, Lynn finds both her real estate agent and Drummond Hall, her beachcomber neighbor, making themselves quite at home. Lynn soon has no doubts of what her scheming neighbors are up to, but she finds Drummond's physical charms hard to resist. And she still doesn't know what really happened to Eloise.
