The body lay there still. Blood pooled beneath the desk. Detective Chen knelt down slowly. Moonlight filtered through the window. A knife glinted on carpet. The victim wore red silk. No sign of forced entry. Someone knew this room well. Chen touched the cold hand. Rigor mortis had set in. Time of death was close. The clock struck midnight now. A shadow moved outside quickly. Chen drew his service weapon. Silence filled the empty house.
