Going wrong - Ruth Rendell

TILL DEATH DO US JOIN...Ever since they ran with the same London teenage gang Guy Curran has loved Leonora Chisholm passionately. He was a slum kid, and her parents lived in tasteful Kensington; she went to university while he made his jet-set fortune dealing drugs and sentimental, mass-produced art--but he's always been good enough for her, and once they were lovers. Of course she'll marry him in the end--he's been calling her every day for years and buying her lunch every Saturday. Then Leonora tells him she's engaged to some pasty-faced intellectual. But Guy knows she's being brainwashed by her family and friends--from her snobbish brother and her mother with pointy silver fingernails to her so-superior feminist roommate. Leonora and he belong together...If he can't have her, he'll die--or someone else will.
