Rain hammered the glass roof of Bellwether Manor while its guests waited for dinner and someone upstairs quietly stopped breathing. At eight precisely, the conservatory lights failed, and a single silver dessert spoon chimed once against the black marble floor. Inspector Mara Venn found him beneath the cedar stairs, one hand cupped around a key that fit no known door. The dead man was their host, though his dinner plate remained untouched beside a single rose and an unsigned confession. Every guest denied writing it, yet each recognized the paper, torn from the household Bible before the storm finally began. Then a telephone rang inside the locked library, and Mara heard her own voice whisper the name of another victim.
