Detective Mara Stone arrived at the old Blackwood estate precisely as the last amber sunlight faded behind the distant hills. A body lay crumpled at the foot of the grand staircase, surrounded by shattered glass and scattered crimson rose petals. The victim's wide eyes remained open, frozen in an expression of absolute terror that no living face could ever replicate. Rain suddenly began to fall, drumming against the windows like impatient fingers tapping on a table during an awkward silence. Someone in this house had committed an unforgivable crime, and every single shadow now seemed to conceal a dangerous secret. Stone knelt beside the body, carefully studying the strange symbol carved deliberately into the pale skin of the victim's wrist. It was a circle crossed by a line, an old mark she had encountered only once before in her career. She quickly turned to the gathered suspects, their drawn faces pale and guilty beneath the flickering chandelier's uncertain golden light. None of them would leave this estate tonight until she uncovered the terrible truth carefully hidden behind their trembling lips. The old clock struck midnight, and somewhere deep within the dark house, a door closed with a soft deliberate click.
