The Other Side of Midnight by Sidney Sheldon

The Other Side of Midnight is Sidney Sheldon at his best. This page-turner is full of tortured romantic entanglements, reverses of fortune, thrilling suspense, and ultimate justice. In Paris, Washington, and a fabulous villa in Greece, an innocent American becomes a bewildered, horror-stricken pawn in a game of vengeance and betrayal. She is Catherine Douglas, a woman caught in a web of four lives intertwined by passion as her handsome husband pursues an incredibly beautiful film star . . . and as Constantin Demeris, a legendary Greek tycoon, tightens the strands that control them all.
