Frost bit the leaded panes of old Blackthorn Manor tonight. Eleven strange guests gathered for the baron’s belated birthday feast. Wax chandeliers flickered once then plunged all to total black. A sharp scream split the hush before matches flared slow. Aging butler Hale found the baron slumped at his desk. A silver letter opener jutted from his cold still throat. The front oak doors stayed locked, no guest had left. A young guest whispered the killer sits right among us.
