Swords and Deviltry (Ace Books, 1970) by Fritz Leiber was originally published in paperback as part of Ace Books’ complete seven volume saga of Fafhrd and the Gray Mouser. Although Swords and Deviltry is first in the series chronology, it was actually the fourth book published.

Leiber and his lifelong friend Harry Otto Fischer created Fafhrd and the Gray Mouser in an exchange of letters in 1934, basing the pair loosely on their own friendship, with Fischer as the diminutive Mouser and Leiber as the towering Fafhrd. The first story featuring the Twain (as they are often called) to appear in print was “Two Sought Adventure” AKA “The Jewels in the Forest” in 1939 in Unknown magazine. A handful of further Fafhrd and the Gray Mouser stories trickled out over the next two decades until Cele Goldsmith commissioned brand-new stories for Fantastic magazine starting in 1959, which lead to the Ace paperback collections of the late 1960s.

Other than the continued interest in Robert E. Howard’s Conan stories, this new appreciation of Leiber’s fantasy fiction was one of the biggest contributors to the sword and sorcery renaissance of the 1960s. In fact, Leiber is credited with coining the term “sword and sorcery” in 1961 when Michael Moorcock called for a name for the type of fantasy fiction that Howard, Leiber and others were coming to exemplify.

By the time Swords and Deviltry was published Leiber had been writing tales of Fafhrd and the Gray Mouser for over 30 years, but it is only in this book that he revealed their full origins in the stories “Induction” (1957), “The Snow Women” (1970), “The Unholy Grail” (1962), and “Ill-Met in Lankhmar” (1970).

Swords and Deviltry featured a typically moody Jeffrey Catherine Jones cover, although the effect is compromised by the trade dress of later printings:

Fafhrd and the Gray Mouser’s gaming history actually predates their first publication, as Leiber and Fischer created a complex three-dimensional board game in 1937 to amuse themselves and help them visualize the Twain’s stomping grounds of the city of Lankhmar and the world of Nehwon. This game was later re-developed and published by TSR as Lankhmar in 1976.

Leiber and Fischer weren’t mere hands-off IP licensors, however. Leiber would contribute a witty conversation with Fafhrd and the Mouser about wargaming in the very first issue of The Dragon (1976), followed by the short story “Sea Magic” in issue 11 (1977). Fischer’s short story “The Childhood and Youth of The Gray Mouser” then appeared in issue 18 (1978).

Lawrence Shick and Tom Moldvay gave Fafhrd and the Gray Mouser their first Advanced Dungeons & Dragons write-up in issue 27 of The Dragon (1979). The Twain and various other denizens of Nehwon were given a whole chapter in James M. Ward’s and Robert J. Kuntz’s Deities & Demigods (1980), with memorably gritty illustrations by Jennell Jaquays.

Future notes on the Fafhrd and Gray Mouser series will cover later TSR Lankhmar publications, post-TSR licensees and other games that have been directly influenced by the city of Lankhmar. Stay tuned!
