Koshchei: The Deathless #4
An encounter at a witches' Sabbath leads Koshchei down a road of betrayal, and in his revenge he comes face to face with the enemy he least expects. Mignola returns to Hell and to the bizarre folklore that's filled some of his greatest books, reuniting with one of his favorite collaborators, Ben Stenbeck (Frankenstein Underground, Witchfinder: In The Service of Angels, Baltimore).
