Two classic solo adventures from TSR.  Snow Pearls is a Companion Level adventure.  Recover the four stolen magical snow pearls before your beautiful village is destroyed by a mad wizard.  Dagger Alley is an AD&D adventure.  Roam the shadowed alleys of Goldstar, avoiding trouble, solving riddles, and overcoming obstacles to achieve your goal.  Both adventures use pre-generated characters and the adventure unfolds bit by bit by use of the Magic Viewer to shepherd you through.  Own a piece of classic D&D nostalgia and see how solo adventures were done before the advent of the internet!  Can be combined with other D&D listings, just ask.
