Bitter cold November rain lashed Blackthorn Manor’s drafty leaded windows. Twelve shaken dinner guests huddled by the sputtering granite hearth. Mara, our sharp housekeeper, stumbled up from the wine cellar. She’d found our reclusive host, face down in crushed ice. The storm had severed every landline and cell tower signal. The local mayor claimed he spent all night playing bridge. Three quiet guests noted he’d left the lounge hours ago. His study safe hung ajar, its heavy iron lock forced. The host’s young niece twisted her engagement ring very tight. Outside, the gale wind shrieked, rattling every loose glass pane.
