Spirited Murder

Stage Five Parlor

Summary
During a mysterious séance at 6 PM, Mrs. Spooked died — seemingly killed by the ghost of her ex-husband, as the medium Mr. Voyant claims. You do not have access to the autopsy report.

Solution
The table was rigged to shoot out a knife instead of making the sound of a spirit knocking. A weight resting on the bottom shelf of a hidden bookshelf door to the cellar, tied to Mrs. Spooked's chair, pulled her closer toward the knife to stab her with it.
