The rain hammered Inspector Davies' lonely coat that cold night. Yellow tape fluttered violently outside the abandoned riverside antique bookstore. Inside, Eleanor Vance lay perfectly still beneath shattered crystal chandeliers. Her outstretched hand clutched a single bloodstained silver pocket watch. Davies knelt carefully, noting the watch had stopped at midnight. "Nobody touched anything," whispered the nervous young constable beside him. Davies frowned, noticing muddy footprints leading toward the back door. Yet the victim's elegant shoes remained completely dry and spotless. Someone else had been present when Eleanor Vance died tonight.
