Rain hammered the precinct windows long after midnight finally struck. Detective Mara Ellis stared at the bloodstained invitation alone silently. The victim had hosted his own funeral last Tuesday evening. Everyone invited watched him toast, then collapse, then laugh maniacally. Tonight, he had actually died during dessert, without any performance. Mara knew every guest had wanted him truly dead yesterday. She tucked the invitation into evidence, smiling without any humor.
