One murky night in Lankhmar, Fissif and Slevyas, members of the Thieves' Guild, steal some valuable jewels from Jengao the gem merchant. While returning to the Thieves' House, they are ambushed by both the Gray Mouser and Fafhrd simultaneously, who steal their gems. Recognizing kindred spirits, they agree to share the loot. They return to Mouser's lodgings, where Fafhrd is introduced to Mouser's woman Ivrian, while Ivrian meets Fafhrd's love interest, Vlana.
Somewhat drunk, Mouser persuades Fafhrd to join him in a quest to infiltrate the headquarters of the Thieves' Guild, in the guise of members of the Beggars' Guild. They are initially successful, but their disguise comes unstuck when the Mouser's glib story is seen through by Krovas, Grandmaster of the Thieves, and the Beggarmaster. Fleeing, they return to Mouser's hovel, only to find to their horror that both girls have been killed and partially eaten by giant rats, as well as by Slivikin, a fast-moving evil witch-beast conjured up by Krovas's warlock, Hristomilo.
In grief and anger, they return to the Thieves' House and charge in, causing panic and chaos. They kill Hristomilo, before fleeing from the city.
