Rain hammered the cobblestone alley. A lantern flickered, casting shadows. Detective Marlowe arrived, trenchcoat dripping. Footsteps echoed from the courtyard. A scream shattered the night. Police tape fluttered around doorway. Inside, a body lay motionless. A silver letter opener glistened. Blood spattered the polished floor. Who killed the wealthy philanthropist?
