Rain hammered the ancient manor. Lightning stitched across the clouds. Detective Mara Quinn arrived late. Patrol cars crowded the driveway. Glass glittered like frost underfoot. The front door yawned crooked. Inside, voices tangled with static. A radio crackled on standby. Uniforms parted as Mara entered. The living room smelled metallic. Blood varnished the Persian rug. A body lay beside fireplace. Eyes stared upward, glassy, surprised. Someone had arranged the hands. Fingers pointed toward the mantelpiece. There, a single photograph remained. Every other frame lay shattered. Mara studied the intact picture. Bride and groom smiled forever. Tonight, only one survived marriage. Behind Mara, someone quietly sobbed. She turned toward the sound. A man clutched a handkerchief. Blood spotted its monogrammed corner. He whispered, barely above thunder. I only locked the door. Someone was already screaming inside.
