A 'collected works' volume

[Stina]

I took this to mean a single-author collection of short pieces, not necessarily a "complete works" tome. I went with Swords and Deviltry which collects three Fafhrd and the Grey Mouser stories. They weren't the first three by original publication date, but the first is Fafhrd alone, the second is the Grey Mouser alone, and the third is their meeting, so it makes sense to call it the first in the series.
