PERFECT WIFE. PERFECT KILLER? A masterly psychological web of people on the edge and the devils that lie beneath their apparent respectability. Engrossing Guardian Susie Harriot, a respected psychiatrist, has been convicted of the brutal murder of a serial killer in her care. It looks certain that she will be given a life sentence, depriving her of her home, her family and her two-year-old daughter. Susie s husband, Lachlan, is convinced she is innocent and is desperate to prove it. Each night, he climbs the stairs to her study and goes through her papers her case notes, her interviews, and the press cuttings from the trial. But the more Lachlan discovers, the more he suspects that his wife has been hiding a dark secret.
