The driving November rain crashed against Hollow Lodge’s frosted windows when the antique mantel clock struck eleven without a hesitation. A ragged bloodcurdling scream burst from the west wing’s third floor suite sending icy chills down every guest’s waiting spine. Marnie, the lodge’s part-time maid, fumbled with her flashlight as she bolted toward the source of that terrible unmistakable sound. The mahogany suite door swung open beneath her hurried touch revealing the tech billionaire slumped face-first across his four-poster bed. A single cracked silver letter opener protruded from his back; no other weapon, fingerprint or clue lay visible that night. Outside the wind howled louder, erasing any faint footstep that might have led the killer away from this grisly scene. Every guest gathered shivering in the hall, each hiding some small secret that could make them the killer’s next target.
