Rain stitched the harbor black when Mara Venn found the lantern burning beside Doctor Vale's locked boathouse at cold midnight. Inside, the famous surgeon lay beneath his own compass, eyes open, one glove missing, salt glittering on his still lips. The door had been barred from within, yet wet footprints crossed the sill and vanished near the empty medicine cabinet. A telephone kept ringing in the study, though every wire had been cut and the exchange reported silence all night. Mara noticed ash shaped like a moth, a theater ticket for yesterday, and blood too bright to be called old. Then the lighthouse coughed once across the water, and somebody behind the stacked ropes began breathing like a careful animal.
