Detective Vance pushed the heavy oak door open without hesitation. Rain splashed against the cracked windows of the dark mansion. He stepped inside the silent hallway and grabbed his flashlight. A horrible metallic smell lingered undisturbed in the damp air. Someone had completely destroyed the grand chandelier above the stairs. Pieces of expensive glass lay scattered across the polished floor. An elderly gentleman bled profusely upon the torn Persian rug. The victim stared blindly toward the carefully painted ceiling vault. Vance noticed a silver dagger protruding from his velvet coat. Footsteps suddenly echoed from the shadows upstairs near the bedroom. The mysterious killer remained trapped inside this thoroughly isolated house. Vance pulled out his loaded revolver and slowly walked forward. Another loud noise crashed somewhere beyond the second floor landing. The very first clue waited patiently in the looming darkness. This complicated murder case was finally ready to be solved.
