Water Margin: The Snowy Night's Flying Letter

On a night when heavy snow seals the mountain, a secret edict stamped with an official seal suddenly flies in from outside Liangshan Marsh. It states that the court is willing to grant secret amnesty, but first requires the surrender of three "chief culprits" to show sincerity. Song Jiang feels this cannot be ignored. Lin Chong suspects this is a scheme to divide them. Wu Song, however, first detects the pine-smoke scent found only in taverns on the edge of the paper. Wu Song must trace the origin of the edict, navigating between brotherly righteousness, courtly traps, and the unspoken thoughts within Liangshan, to first discover who wants this mountain to tear itself apart.
