Set in the fantasy world of Nehwon, the so-called Swords series follows the adventures of these two "larcenous but likeable" anti-heroes. Fafhrd is a tall and brawny Northern barbarian, who originally trained as a singer. He has a romantic view of the world, but mostly gets by through his practical nature. The Grey Mouser is a skilled thief and former wizard's apprentice, who retains some magical ability. He's a lot more cynical than Fafhrd, but is still prone to sentimental moments.
The stories frequently have the characters getting into bar fights and seducing women, but some stories have them on opposite sides of a conflict. But their friendship nonetheless wins through. At the time of writing, I'm working my way through the third collection, Swords in the Mist. But I figured I'd look at stories in the first collection, Swords and Deviltry, which establishes the pair.
- The Snow Women follows Fafhrd chafing under the authority of his overbearing mother. While visiting the Northerners' trading post at Cold Corner, he meets an acrobat named Vlana and elopes with her.
- The Unholy Grail follows The Grey Mouser as he returns from a quest to find that the wizard he apprenticed to has been executed by a Duke who has outlawed magic. He enacts a plot in revenge, with the aid of the Duke's daughter Ivrian, a fellow apprentice.
- Ill-Met in Lankhmar brings the duo together when they meet while ambushing the same party of thieves. They recognise each other as kindred spirits, introduce their respective girlfriends, and embark on a drunken dare to infiltrate the Thieves' Guild.
