Leiber, what are you doing?! First you retconned Fafhrd into a selfish jerk, now you retcon the Gray Mouser into a cruel, abusive warlock! There'd better be some redemption coming.

The prequel story "The Snow Women," written years after the original stories were published, shows a very selfish, lying, cheating, and overall unlikable Fafhrd, very different from the jolly, companionable Fafhrd I knew and liked in the original stories.
