Detective Mara Quinn arrived at midnight despite relentless cold rain. The victim lay sprawled beneath the shattered ancient Fresnel lens. Blood pooled darkly around his still clenched pale left hand. She noticed footprints leading toward the locked narrow service door. Outside, wind howled through cliffs masking any desperate screams tonight. Someone had wanted this tragic murder to resemble an accident. Mara knew immediately that the killer remained inside the lighthouse.
