People almost forgot. Until thirteen years later, when six envelopes land at the doorstep of six households in town: We cordially invite you to a celebration on the 31st of October this Saturday evening at the Amadeus household.

So begins the mystery of who was really responsible for the missing girl thirteen years ago. Was it Duchess von Pelt, whose face no one has ever seen? Mrs. Raven, the keeper of the local inn? Wormwood, the Amadeuses’ mysterious caretaker? Dr. Foozle, the town pharmacist? Count Baines, who seems to know when unlucky things are about to happen? Judge Ophelius, who presided over Beatrice’s case originally? Mr. and Mrs. H, a couple who no one can ever quite remember?

The guests must work together to identify the guilty party among them over the course of the evening—but beware the ticking clock, because at midnight, everything is going to change! Told from different perspectives, this is a sly, darkly funny mystery. Filled with strange characters and set in a mansion deep, deep in the woods.
