Who killed the Archmage? Was it Tordek in the Dungeon with the Flaming Battle Axe or Mialee in the Magical Armory with the Mace of Disruption? A group of heroic adventurers has been called to the Archmage's castle. But one of those heroes isn't who he or she appears to be.

One of the heroes is a doppelganger, a monster that can look like anyone! In the darkest part of the night, the doppelganger kills the Archmage, triggering a spell that seals the castle until the monster is caught. Now, in the grand tradition of CLUE, the six suspects must determine who among them is the murderous doppelganger: Regdar the Fighter, Tordek the Dwarf, Lidda the Rogue, Mialee the Wizard, Ember the Monk or Nebin the Gnome. The heroes try to figure out Who killed the Archmage, Where the crime occurred, and What magical weapon was used.
