The door creaked slowly open. Rain poured outside the window. Detective Miller entered the room. Blood stained the white carpet. A body sprawled on floor. The victim wore yellow pajamas. His face contorted with fear. Miller knelt beside the corpse. Something glittered beneath the sofa. A knife with jeweled handle. No fingerprints would be found. Miller noted the crooked painting. The safe behind stood open. Family photos littered the desk. One frame remained face down. Miller carefully lifted it up. A woman smiled beside victim. Her face had been scratched. This murder was deeply personal.
