Heavy rain drummed against the cracked window glass with a relentless rhythm that filled the silence of the old house. A crimson stain bloomed across the velvet carpet like a dark flower spreading its deadly petals everywhere in the room. Detective Miller stepped forward with trembling hands and a heavy heart as the truth began to reveal itself so slowly. The lifeless body lay sprawled near the fireplace with eyes wide open staring at the ceiling in terror and shock. A silver dagger lay resting upon the wooden floor beside the victim while its blade gleamed cold in the light. Someone had entered this locked room and left no trace of their presence behind except for blood on the wall.
