Laura discovers Katy and Tom's affair, resulting in Katy's husband Liam leaving her. Meanwhile Vanessa Harmon is unwise enough to accept a drink from Andrew, leading to a trip to hospital whilst Andrew hides a bag in his mother's shed. Laura then turns the tables on Andrew by drugging him and tying him up, threatening castration until he admits his infidelity caused Mary's suicide. However he breaks free and goes after her, pointing out to her how Vanessa, now in the same position as Laura, cannot arrest him.
