16-18. Three Fafhrd and the Gray Mouser books by Fritz Leiber

These are the first three in the Fafhrd And The Gray Mouser series by Fritz Leiber:

1. Swords And Devilty
   
2. Swords Against Death
   
3. Swords In the Mist

These are fluff, pure and simple, though they are somewhat fun fluff. After reading all three of these books none of the characters except Fafhrd and the Mouser themselves are at all memorable, but that's OK. Each has a magical advisor/nemesis as well - one with seven eyes, I recall - but I can't tell you their names nor which goes with which main character.

I found the plots somewhat thin and the resolutions somewhat weak, but that really didn't bother me. I think reading these books is about the atmospherics. Many of the tropes of fantasy are present in them - a thieves guild, mysterious mages of unspeakable power, strange events, etc.

The most disappointing thing about these books is how much action takes place off stage. It seems that Leiber is always telling us that there were other adventures that the heroes have been on that set the stage for what they're seeing and doing now, but we never hear about those adventures except for the sentence telling us they happened.

These are not great literature, but they are kind of fun. I might read more - there are seven or eight, at least, in the series - or I might not. Time will tell.
