The old manor glowed faintly under the heavy evening rain. Detective Mara Voss stepped from her unmarked car, collar raised. A single light burned in the library's tall arched window. The front door stood open, swaying with the wet wind. She stepped inside, finding the marble floor slick with rain. A grandfather clock ticked slowly somewhere in the dark hall. Then Mara heard a wet cough from the library door. She drew her flashlight, moving toward the sound without speech. The library door hung crooked from one bent brass hinge. Inside, an overturned armchair lay beside a shattered crystal decanter. A woman's body sprawled by the dead fireplace, throat cut. Mara knelt beside her, pressing two fingers to the neck. The flesh was cooling, but a faint pulse still beat. The woman coughed blood and whispered a single word: "Cellar."
