I've been really pernickity this month, as to my mind the theme required more than simply one question in the text, and preferably for the whole story to provoke questions of its own. I also thought some stories failed the genre test, even using a wide definition of historical speculative. Added to which, as ever, there were a few stories I simply didn't understand.
So, a shorter short list this month, but all the more select and special for it!
AnRoinnUltra -- Ah sure nobody'll ever know the difference
Cat's Cradle -- Herstory
BigJ -- Empathy; Doubt; Defiance
Elckerlyc -- Delphi (occupied Greece), 20 June 1941
Phyrebrat -- A Question of Faith
Stable -- Quiet Evil
And my vote goes to
Stable, for his take on the witchfinder's questions, and coming a close second
Elckerlyc, with his oracle questioning and ready to be questioned.
Many mirror-voiced thanks for the lovely mentions and shortlistings BTJ, Phyrebrat and CC, and hallucinatory thanks for the wonderful vote ARU! And for the stealth vote, reiver!
