"in late 2013 Google Books digitized an anthology which included 'Flowering Dagger', a story that Sutcliff’s estate, not to mention fandom, was not previously aware of."

I knew of it! I ran across it and photocopied it in the 1990s (from its 1994 reprint, I think). But I didn't find the Sutcliff fandom till you folks had already rediscovered it. :)

Thank you so much for another treat!
