Model response

Rain hammered the old mansion while thunder rolled ominously overhead. Detective Hale stepped quickly inside, shaking water from his coat. The butler stood frozen, pale and clearly terrified of something. Behind him lay a body, sprawled across the marble floor. Blood pooled slowly, spreading beneath the victim's motionless outstretched hand. Hale knelt down carefully, examining the wound with practiced eyes. No weapon remained nearby, only silence and the storm's fury. Someone in this house, he thought, was hiding dark secrets.
