A sharp scream burst from the locked wine cellar below stairs sending wealthy guests scrambling to find what had happened. They kicked in the wooden door to find their host, Hugh Voss, slumped over a crate of 1982 Bordeaux wine. A crystal stalactite paperweight lay beside his bleeding temple, its surface wiped almost completely clear of any trace of fingerprints. The flickering overhead lights cut out suddenly, leaving the group trapped in total darkness that stretched beyond the cellar’s threshold. Someone in the hushed crowd breathed that the missing maid had warned of ghosts hunting the manor’s guilty secret keepers.
