Rain polished the cemetery gates. Detective Mara Vale arrived alone. Her headlights swept the chapel. A single window glowed upstairs. The caretaker waited beneath it. His hands trembled around keys. “Nobody heard the gunshot, detective.” “But everybody heard her scream.” Upstairs, a woman lay dead. Snowdrops filled her open mouth. Beside her lay a photograph. It showed Mara’s entire family. Every face bore black ink. Except the child beside Mara. That child vanished decades earlier.
