This Two Thousand Year-Old Sorceress Had the Power to Turn People into Shadows! Here is A. Merritt's masterwork, our publisher's pick for the best of all his classic fantasies. Creep, Shadow! Is based on legends of Ys and an old Breton song. "Fisher, fisher, have you seen/White Dahut, the Shadow Queen/Riding on her stallion black/At her heels her shadow pack?"
