The lighthouse lamp swung, but nobody tended it tonight anymore. Detective Mara Quinn arrived soaked, clutching her dead father's badge. The body lay beneath the Fresnel lens, still glowing faintly. Blood pooled strangely, spelling nothing, yet suggesting everything terrible somehow. "He was supposed to meet me," whispered the keeper's widow. Quinn noticed fresh footprints leading outward, but none returning inside. Then the light died completely, leaving them in accusatory darkness.
