A Clearing in the Fog: Daria Macomber

This book reminded me of Rebecca. The tone is similar and they are both about women who get involved with men, not knowing their past. In this book, a girl meets an older mysterious man through a friend and jumps at the chance to visit him in his home in the south after he invites her. Once she gets there she learns he is married. She also learns his wife mysteriously disappeared and the rumors vary between he killed her and that she ran off with another man. As the story progresses she learns that the wife- Adele- was pregnant right when she vanished. The protagonist spies on a friend of Adele who she believes is black mailing someone. While she is hiding in the hotel bathroom he ends up getting shot. Everyone becomes a suspect until she goes to the beach on an island with one of Adele's girlfriends and it is all revealed. This friend thought Adele was pregnant with her husband's child and shot her, then hid her on the island.
