So Wa Reirei No Yukini Mai其は怜々の雪に舞い; Dancing in the Swirling Snow; So wa Reirei no Yukini Mai

Set in the Taisho era (1912-1926). Two years after the famous author Uro vanishes, his last manuscript is found at the house of competing author Otogai, who seems obsessed with (or is it possessed by?) the dead man, even as Otogai's garden seems haunted by a mysterious cameilla bush.
