Swords of Deceit (1986)

From the Back of the Book:
In the dead of the night, a ghastly fog shrouds the deserted streets. Doors are locked, windows shuttered, as a deathly silence haunts the shadows. Almost all of Lankhmar's citizens cower in their homes. Tonight the streets and alleys of Lankhmar belong to the ancient gods--this is the Night of Fear.

Whose life will be lost this night--a lonely wench abandoned in the street? Perhaps a young noblewoman betrayed by her family? You can find out, as you venture into the dark and winding streets of Lankhmar. But beware, eyes are already watching you.

In addition to the book, the module includes an unattached foldout cover (containing a map, tables, and pre-rolled characters) and a 32"x21" color map of the Lankhmar sewer system.
