Swords and Deviltry by Fritz Leiber
Called a short story collection but that's not really true. Follows Fafhrd and the Grey Mouser before they meet. Skips very slighty over when they first reach Lankhmar then continues with the two hero's together. Good book.

Has a torture scene. (Why are those always the best books?) The Grey Mouser being tortured by the duke. Through black magic he survives/escapes. The two hero's are basically interesting. Fafhrd escaping a barbaric upbringing through some intelligence. Both though are slighty stupid but in a fun way. Almost just fun and lighthearted, except that main characters do actually die gruesome deaths.

Eh. Think I'll continue with the 7 book series.

Not in first person. (But how could that work anyway with two equally prominent main characters whom are together?) The Grey Mouser at least sort of has an ace up his sleeve. Or at least one hopes/expects. Ultimately though they just get lucky in book one. One would like to think the Grey Mouser will become a great wizard. And that Fafhrd will develop some ninjawhatever abilities. They do suffer injustice. The Grey Mouser more so, but both to an extent.

Not entirely devoid of deeper thoughts. The particulars of Fafhrd's dystopian upbringing are somewhat interesting.
