A Wealthy Family’s Battle With Drugs Laid Bare, but to What End?br “The bedroom contained the addiction; the rest of the house felt like a front for the recovery they, or we, had hoped for, the family life they, or we, had wanted — a Potemkin facade of affluencebr and stability,” Ms. Rausing writes in “Mayhem,” which comes out next month from Knopf.br Mr. Kemeny “denies that a drug relapse makes people bad parents, which he must know isbr an astonishing denial of the reality of drug addiction,” she wrote in a statement.br “It may have been another sibling thing between us,” she adds, “My depression,br his addiction; a similar emotional deficiency, or a similar emotional state.”br After the police discovered Eva’s body, Mr. Rausing pleaded guilty to preventing the lawful and decent burial of a body.br Eva’s father, Tom Kemeny, has accused Ms. Rausing, the editorbr and publisher of the literary magazine Granta, of excavating her family’s addiction for her own literary ends, raising the question of whether the lines between memoir and voyeurism, family catharsis and score-settling, have been blurred.
