Rain taps the window softly. Thunder growls beyond the glass. A scream splits midnight air. Detective Mara Vale arrives alone. Her coat drips cold rain. The mansion looms before her. Inside, a body waits silently. Blood pools on marble tiles. A knife glints beside him. No witnesses speak a word. Mara kneels near the corpse. She whispers, "Who killed you?" The clock ticks too loudly. Then footsteps echo upstairs suddenly. Someone else is inside now. Mara draws her service weapon. The mystery begins right here.
