No-one wept for Billington Smith, nor mourned his passing. Over the weekend, he'd given everyone cause to wish he was dead: violently disinheriting his son, humiliating his wife most publicly, refused to help his nephew out of money troubles and made it clear he loathed his son's fiancee. And his sister in law made him the most furious - she's not scared of him at all. Quite a cast of suspects.
