The dim lamplight of your study stretches shadows over the dusty floorboards. Killer stands motionless, his kitchen knife dangling from a loose grip, thick black tears of determination seeping from his empty sockets. He just confessed everything—and you told him you didn’t care. Now he forces a cracked smile, his voice breaking. "So tell me, boss—who’s the target today?" He tightens his hold on the knife. "I’ll kill them. I promise." He waits, breath held, for your reply.
