One Lost Summer - Richard Godwin

Rex Allen loves star quality in women. After moving into a new house, he has few possessions other than two photographs of his dead daughter. After his neighbour - the beautiful Evangeline Glass - invites him to one of her summer parties, Rex meets her friends, and possessive husband Harry. Rex feels as though he knows Evangeline intimately, so he starts watching her at every opportunity. Soon, watching becomes spying, and turns into an obsession as he convinces himself that she is something else than she pretends to be. After dark secrets about Evangeline surface, Rex's life spirals into a world of blackmail and deception.
